[1:10] <Kdecherf> I spotted a strange behavior on MDS/ceph-fuse: some folders disappear (but still exist, a restart of the active mds is enough)
[1:10] <slang1> Kdecherf: what's your application workload?
[1:11] <slang1> Kdecherf: its not something you see with the cephfs kernel client?
[1:12] <Kdecherf> slang1: a "lot" of IO, some cp/rm, a global chmod and a ls
[1:12] <Kdecherf> slang1: the pool is small (7GB data, 340k objects)
[1:12] <Kdecherf> I didn't see it on the kernel client atm
[1:13] <slang1> Kdecherf: bobtail?
[1:14] <slang1> Kdecherf: did you try remounting the ceph fuse mountpoint (without the active mds restart) and still saw the same behavior?
[1:15] <slang1> Kdecherf: I can understand not wanting to do that (restarting the mds can sometimes be easier)

[3:46] <xiaoxi> Hi, my ceph cannot push my disk to 100% utils, since I have enough clients(128~480 rbds), i suppose the disk should be 100% busy..
[3:54] * sjustlaptop (~sam@71-83-191-116.dhcp.gldl.ca.charter.com) has joined #ceph
[3:54] <phantomcircuit> xiaoxi, how many disks and how are you measuring disk utilization
[3:55] * Cube (~Cube@cpe-76-95-223-199.socal.res.rr.com) has joined #ceph
[4:02] <dmick> xiaoxi: there are many places for bottlenecks; without discussing the configuration in detail it's difficult to discuss performance
[4:28] <paravoid> sagelap: hey
[4:29] <paravoid> so, any tips for optimizing ceph for small object sizes?
[4:29] <paravoid> performance is quite sucky
[4:34] <paravoid> rados bench for 4MB files is ~107MB/s, for 1MB ~60MB/s, for 512K ~30MB/s, for 256K ~20MB/s for 64K ~5MB/s, for 4K ~0.3MB/s
[4:35] <dmick> paravoid: do lots of them at the same time? :)
[4:36] <phantomcircuit> dmick, actually that doesn't seem to help
[4:37] <phantomcircuit> paravoid, put flashcache in writeback mode in between the journal and filestore...
[4:37] <paravoid> erm
[4:37] <paravoid> journal is raid0 SSDs and disks are behind a BBU
[4:38] <phantomcircuit> paravoid, try increasing the number of disk threads
[4:38] <paravoid> osd op threads?
[4:39] <phantomcircuit> yeah
[4:39] * nhm (~nh@184-97-251-146.mpls.qwest.net) Quit (Read error: Connection reset by peer)
[4:39] <paravoid> to what is your suggestion?
[4:39] * nhm (~nh@184-97-251-146.mpls.qwest.net) has joined #ceph
[4:39] <phantomcircuit> paravoid, it's hard to know what the limiting factor is without having statistics for resource usage underload
[4:40] <phantomcircuit> so without them im basically just guessing
[4:42] <xiaoxi> phantomcircuit:120 disks, I measure disk utilization by iostat

[5:04] <dmick> elder: if you mean tracker, It Works For Me; I can reset passwords if that'll help
[5:04] <dmick> xiaoxi: so between 3 and 4 disks per node
[5:05] <xiaoxi> no,20disk per node
[5:05] <dmick> oh
[5:05] <xiaoxi> 120 in total
[5:05] <dmick> 1 10Gb NIC per node?
[5:05] <xiaoxi> yes
[5:06] <xiaoxi> 10Gb for data traffic and an 1Gb for monitor and management
[5:07] <phantomcircuit> xiaoxi, small io or large io?
[5:08] <xiaoxi> I have tested both, for 4K random io ontop of RBD, the backend disks ultilization are significant higher than that of 64K sequential io
[5:12] <dmick> so theoretical max for the NIC is, say, 1.25GB/s? let's say the disks could do 130MB/s sustained (I'm assuming they're 7200RPM)? For 20, that's slightly less than double what you can feed them with the NIC, right? Are my numbers working?

[5:13] <dmick> (I suck at these sorts of estimations)
[5:14] <xiaoxi> dmick:yes,your numbers working,but the disks cannot be 130MB/s for RBD load, the typical bandwidth is ~ 30MB or less

[5:17] <xiaoxi> it's far away from 100% ultilized.

[8:38] <ctrl> Hello everyone
[8:38] <nz_monkey> In my learning the ins and outs of CEPH I have managed to do something stupid. I wanted to move a bunch of OSD's from spinners to ssd's, instead of marking the OSD's as down and removing them, I marked them as out and stopped the OSD process, I then put the new devices to the same mountpoint and pushed the OSD key on to them and then brought started the OSD process. As you can imagine, I now have a huge amount of stuck unclean and
[8:38] <nz_monkey> quite few stuck stale PG's. What is the best way to go about fixing this up ?

[12:17] <joao> ctrl, here now
[12:17] <joao> overslept for 2 hours
[12:18] <joao> topro, think so
[12:19] <joao> actually, no
[12:20] <joao> the default crushmap sets the osd bucket as the placement rule, iirc
[12:20] <joao> so you'd have your data replicated across osds, not hosts
[12:21] <joao> that could mean that one given pg could end up being replicated on only two hosts
[12:22] <madk> Hello
[12:22] <joao> hi
[12:22] * loicd (~loic@3.46-14-84.ripe.coltfrance.com) has joined #ceph
[12:23] <madk> im trying to get phprados to speak to my rados cluster using cephx authentication. the examples from phprados state a configuration option for the keyring to use, but i am unsure on how to tell phprados which username to use.
[12:24] <ctrl> hi
[12:25] <ctrl> after change replica to 2 and restart ceph
[12:25] <ctrl> now health is ok
[12:25] <joao> ctrl, yeah, I'd figured changing the replica would fix it, but I don't see why you'd have to restart ceph
[12:38] <ctrl> joao: when default crushmap generates?
[12:40] <joao> it is not so much generated, afaiu, but it is more like the default settings plus whatever you specify when you add an osd to the cluster
[12:40] * xiaoxi (~xiaoxiche@134.134.139.76) Quit (Remote host closed the connection)
[12:41] <joao> I'd have to go digging for the code that handles that, but I don't think that is what you want, is it?
[12:44] <joao> anyway, if no map is fed to the cluster, it has a set of implicit rules (data, metadata and rbd) with a set of default assumptions (such as steps), and a root; as you are adding osds to the cluster, the crushmap adapts to reflect where you're placing your osds (say, rack, row, w/e)
[12:50] <gucki> joao: do you know why ceph mon tell \* injectargs '--mon-osd-nearfull-ratio 86' does not work? the full osd is at 85%, so it should work?
[12:52] <joao> gucki, the default value for that option is '.85'
[12:52] <joao> so I'm assuming you should specify it as .86?
[12:52] <joao> or 0.86
[12:52] <joao> ?
[12:52] <gucki> joao: ok, i'll try that... :)
[12:53] <joao> let me know how it works out

[12:57] <topro> joao: ok that describes what I see. so how would I have to change my crushmap to achive replications across seperate hosts?
[12:57] <joao> topro, http://ceph.com/docs/master/rados/operations/crush-map/
[12:58] <joao> in a nutshell, obtain crushmap from cluster; decompile it; edit it; compile it; feed it to the cluster
[12:58] <joao> ah, you mean what you'd have to change in the crushmap
[12:58] <topro> joao: yea
[12:59] <joao> on the placement rules, setting 'host' as the bucket type on 'step chooseleaf ...' instead of osd should do the trick
[13:00] <topro> joao: thanks a lot. i'll give it a try
[13:00] <joao> topro, I advise you reading that doc
[13:00] <joao> it's insightful in many ways
[13:00] <joao> :)
[13:00] <topro> i will, promised ;)
[13:01] <Gugge-47527> my default non changed crushmap has "step chooseleaf firstn 0 type host", so it should be good right?
[13:03] <joao> should be right, yes
[13:03] <joao> I assumed the default was always 'osd' as it is what I see on my test cluster
[13:04] <joao> I'll try to remember to dig for it when I have the time, to put this question out of its misery
[13:04] <Gugge-47527> im not sure i understand the firstn 0 part

[13:15] <joao> gucki, quoting sjust from earlier this month
[13:15] <joao> [1:32] <sjust> ceph mon tell \* -- injectargs '--mon-osd-full-ratio=0.98'
[13:15] <joao> [1:33] <sjust> that'll bump it to 0.98
[13:15] <joao> [1:33] <sjust> you really don't want to leave it like that
[13:16] <joao> s/0.96/0.86
[13:16] <gucki> joao: ah, probably i missed the =
[13:16] <joao> yep, and so did I ;)
[13:16] <gucki> joao: i also want to change the *near* full, not the full ratio :)
[13:16] <joao> same goes for that one
[13:17] <joao> didn't even noticed that though
[13:17] <topro> joao: i you don't mind, thats my crushmap http://paste.debian.net/230052/
[13:17] <joao> I clearly need more coffee before my reading skills are back to normal
[13:18] <gucki> joao: does not work for me ceph mon tell \* injectargs '--mon-osd-nearfull-ratio=0.86'
[13:18] <topro> joao: if i get it correctly, "step choose firstn 0 type osd" doesn't mind on howw to distribute replicas, it selects by random choice?
[13:18] <joao> topro, 'type osd' will choose from osds
[13:19] <joao> as in, if you have 12 osds distributed across 3 hosts, replication 3 will ensure 3 osds will get the same pg, but will disregard where said osds are
[13:19] <gucki> also this does not work: ceph mon tell \* -- injectargs '--mon-osd-nearfull-ratio=0.86'
[13:19] <topro> joao; but to choose from type host i would have to replace "step choose firstn..." with chooseleaf, right?
[13:19] <joao> topro, ah, that I don't know :x
[13:19] <joao> let me get back to you on that one
[13:19] <topro> nevermind, I will find out the hard way ;)
[13:20] <topro> is there a chance to kill my data by stuffing around with crushmap?
[13:21] <joao> don't think so
[13:21] <joao> it will shift data around for sure though
[13:21] <topro> ok, i'll just go and see :|
[13:22] <joao> gucki, do you have debugging on the monitors?
[13:22] <joao> you should be able to see what's going on
[13:22] <joao> when that command is received
[13:23] <gucki> joao: is this enough? http://pastie.org/pastes/5929856/text
[13:24] <joao> gucki, well, it is applying the configuration change
[13:24] <joao> it says so in the log
[13:24] <gucki> joao: it's always telling so, no matter what you pass to injectargs ;)
[13:24] <gucki> joao: but it doesn't change anything..
[13:24] <joao> ah
[13:24] <joao> let me go check that
[13:25] <gucki> joao: using argonaut 0.48.2
[13:25] <joao> oh
[13:25] <joao> I don't really recall how this used to work on argonaut
[13:25] <joao> but I'm going on a limb and assume there's the possibility of this not being supported or something
[13:26] <joao> checking it though
[13:28] <topro> joao: fyi replaced "step choose firstn 0 type osd" with "step chooseleaf firstn 0 type host" as "...choose... type host" would do as it says, choose a host, not an osd. chooseleaf instead chooses a random leaf below the host
[13:29] <topro> its rebalancing now and pg dump looks promising, so far
[13:29] <joao> topro, thanks for letting me know :)
[13:30] <topro> nevermind, i think I just got how crushmap basics work, thanks ;)
[13:31] <topro> another question, is tunables something i want to know about?

[15:53] <Kioob`Taff> (I have only 1 network card per host)
[15:53] <Kioob`Taff> is it possible that the problem came from the fact that there is only one monitor, hosted on one of this hosts ?
[15:53] <Kioob`Taff> (OSD hosts)
[15:55] <Kioob`Taff> I had 15 minutes of downtime of the entire cluster :/

[19:34] <wer> with rest-bench "seq" option, is one expected to throw the --no-cleanup flag in oder to have sequential objects to read? Also is there any provision to specify a new write starting point to add additional objects instead of overwriting them?

[19:36] <wer> heh. hmm. I see some gets also from performing a write yesterday.... hmm.
[19:37] <wer> oooh. nm. that was me getting all the objects. So in order to put 1M objects in the test bucket I must let it run for 60k seconds with 20 concurrency or something to that effect?

[19:38] * dosaboy (~gizmo@faun.canonical.com) Quit (Quit: Leaving.)
[19:38] <yehudasa> 60k seconds? that's like 20 hours
[19:39] <wer> yup :)
[19:39] <yehudasa> I don't think so, unless your performance is really bad
[19:39] <yehudasa> ah, 1M objects
[19:39] <wer> I am limited now by 1gig links.
[19:39] <yehudasa> so you basically want to transfer a terabyte

[19:48] <noob2> is there code in the python library to create rados gateway users?
[19:48] <noob2> if not i'll just use subprocess :)
[19:49] <pja> sorry yehudasa, im back
[19:49] <pja> yeah i make a cname entry in our dns
[19:50] <pja> are you still there?
[19:52] <wer> might be nice to add some object naming features (start seq and or naming) to rest-bench for use cases such as continuing... using existing objects..., and or using it to populate a lot of objects in a bucket. block size randomness would also be nice to some degree.
[19:53] <yehudasa> pja: yeah
[19:53] <yehudasa> wer: right
[19:54] <yehudasa> wer: rest-bench is basically doing whatever 'rados bench' is doing
[19:54] <pja> is it possible to write email?
[19:54] <wer> yehudasa: oh ok. Maybe I should be digging into rados bench :)
[19:55] <yehudasa> pja: if you can't do it here, you can try sending mail to ceph-devel, but chances are that I'll be the one to pick it up
[19:55] <yehudasa> wer: both share a common infrastructure

[20:08] <pja> can i write to the mail address without subsribing or sthg like this?
[20:08] <pja> can i ask from which country you are

[20:09] <dmick> it's not super-high-volume, and a lot of it can be useful information about Ceph, though

[20:16] <pja> and configure it like this:
[20:16] <pja> http://ceph.com/docs/master/radosgw/config/
[20:17] <pja> can you open the 2nd link please?

[20:17] * LeaChim (~LeaChim@b01bd420.bb.sky.com) Quit (Ping timeout: 480 seconds)
[20:17] <pja> i read on some pages there have to be the fqdn
[20:18] <pja> is it right?
[20:18] <pja> because in the ceph conf it was always only the hostname, not the full domain name
[20:19] <pja> next part: "CREATE RGW.CONF"
[20:19] <yehudasa> pja: yeah
[20:19] <pja> so fqdn or only hostname?
[20:19] <yehudasa> oh, not sure .. whichever works to start up the daemon
[20:19] <yehudasa> if the daemon runs then it's ok
[20:19] <yehudasa> it's used in /etc/init.d/radosgw
[20:20] <pja> that is another point, radosgw not running
[20:20] <pja> i thought its startet from the fastcgi script
[20:20] <dmick> it needs to match $(hostname)

[20:21] <yehudasa> it's not recommended to let fastcgi control its lifecycle
[20:22] <dmick> pja: yes I think so too. hostname takes -f for fqdn

[20:31] <dmick> not after (11:22:14 AM) dmick: pja: yes I think so too. hostname takes -f for fqdn
[20:31] <dmick> seems like task one is to get radosgw running
[20:31] <pja> when i type "/etc/init.d/radosgw start" i get no output
[20:31] <pja> on the console
[20:31] <pja> ps ax says no radosgw running
[20:32] <dmick> perhaps reading radosgw and looking at the things it checks would be fruitful
[20:32] <pja> pardon?
[20:32] <pja> dont understand
[20:33] <dmick> less /etc/init.d/radosgw
[20:33] <dmick> look for start)
[20:33] <dmick> see what it does
[20:33] <dmick> and what's going wrong
[20:35] <pja> for name in `ceph-conf --list-sections $PREFIX`; do.....
[20:36] <dmick> yes, looking for client.radosgw. sections
[20:38] <pja> PREFIX='client.radosgw.'
[20:39] <pja> at the beginning
[20:39] <dmick> right
[20:39] <pja> sorry, its the standard init script, i install rados gw via apt-get
[20:39] <pja> nothing changed in the init script
[20:39] <dmick> we're debugging your problem
[20:39] <pja> im sorry
[20:40] <dmick> so first it checks that you have not set 'auto start = no" or "false" or "0" in that section of ceph.conf
[20:40] <dmick> which I assume you have not
[20:40] <pja> no
[20:40] <dmick> then it checks for "rgw socket path", which you must have for auto startup
[20:40] <pja> its the standard ceph.conf of the website
[20:40] <xmltok> i dont think i ever had the init script work during my testing, i was running it like this manually: /usr/bin/radosgw -c /etc/ceph/ceph.conf -n client.radosgw.gateway
[20:40] <dmick> then it checks that "host" matches $(hostname)
[20:41] <dmick> if all those are true, it should proceed to "Starting..."
[20:41] <pja> yeah this is was the fcgi script does
[20:41] <dmick> so clearly one of those must not be true
[20:41] <pja> what is not true?
[20:41] <dmick> one of those three tests
[20:42] <pja> ive no knowledge in scripting
[20:42] <pja> but when i look in the init script
[20:42] <dmick> but this isn't scripting, this is just basic decision making
[20:42] <pja> i cannot find the dir of ceph or something, so who does it know the correct path
[20:42] <pja> who=how
[20:43] <dmick> RADOSGW=`which radosgw`
[20:43] <dmick> start-stop-daemon --start -u $user -x $RADOSGW -- -n $name
[20:43] <dmick> is how it finds the executable
[20:43] <dmick> why don't you pastebin your ceph.conf and I'll look at those three conditions for you
[20:43] <pja> wonderful
[20:45] <pja> http://pastebin.com/ynAUNhqy
[20:46] <dmick> that's not ceph.conf
[20:46] <pja> ahh sorry i thought you mean the init script
[20:47] <dmick> then I would have said /etc/init.d/ceph
[20:47] <dmick> and as we know, you're using the default one, so I have that
[20:48] <pja> [global]
[20:48] <pja> http://pastebin.com/BR24JaaD
[20:48] <dmick> please don't paste it here
[20:49] <pja> copy paste fault
[20:49] <dmick> so that looks like an FQDN in the hostname
[20:49] <dmick> which we established above was not correct
[20:50] <dmick> that's condition 3 of the conditions I enumerated above
[20:50] * ScOut3R (~ScOut3R@rock.adverticum.com) has joined #ceph

[20:50] <pja> at the bottom?
[20:50] <dmick> I think maybe you misunderstand the overall intent of the process here
[20:50] <dmick> you're adding things to ceph.conf

[20:51] * ctrl (~ctrl@128-72-212-31.broadband.corbina.ru) Quit (Ping timeout: 480 seconds)
[20:51] <dmick> ceph.conf has several sections, as you can see
[20:51] <dmick> one of them is the radosgw section
[20:51] <dmick> that's the one you've added things to
[20:51] <dmick> (missing the leading tabs, but I think that's accepted)
[20:51] <dmick> in that section are all the things that affect radosgw
[20:51] <dmick> there is one hostname in that section
[20:51] <pja> yeah your right
[20:52] <pja> "Starting client.radosgw.gateway..." ;)
[20:52] <pja> i had this before
[20:52] <pja> as you can see this dns entry is also from another article

[20:53] <pja> thank you :)
[20:53] <pja> the problem is
[20:53] <pja> therefore i asked for the timezone
[20:53] <pja> we have 9 o clock in the evening here
[20:53] <pja> so theres no deeloper
[20:53] <pja> i dont think that this solves my problem
[20:54] <dmick> no developer where?
[20:54] <dmick> the email list is worldwide, as is IRC
[20:54] <pja> i mean on our site
[20:54] <pja> who can test our environment
[20:54] <pja> im not a programmer
[20:54] <pja> sysadmin for setting up this system i dont know
[20:55] <pja> so i cannot test if it solves my problem
[20:55] <dmick> ok, I can't help you there
[20:55] <pja> but thank you for that first step ;)
[20:55] <dmick> but I will note that email is less synchronous than IRC, and handles timezone differences better
[20:55] <dmick> but, use whatever support channel you feel is best
[20:55] <pja> yeah with pastebin its okay
[20:55] <pja> its directly
[20:56] <pja> has radosgw a webinterface?
[20:56] <pja> because i dont understand
[20:56] <pja> that i created ssl certificates and so on
[20:56] <pja> - how does the rados know where i put them?
[20:57] <pja> 1. the virtualhostconf says *:80
[20:57] <dmick> What do you believe radosgw is for?
[20:57] <pja> i think you need it to interact with the s3 api
[20:58] <dmick> and the s3 api uses HTTP as a transport
[20:58] <pja> not https?
[20:58] <dmick> whichever
[20:58] <pja> yeah but theres my question
[20:58] <pja> i create the ssl certificates
[20:59] <pja> but i dont have to put the path to them or activate the sslengine in the apache conf
[20:59] <pja> so how does rados know where they are
[20:59] <dmick> http://ceph.com/docs/master/radosgw/manual-install/#enable-ssl does that help?
[20:59] <dmick> rados doesn't do SSL, Apache does
[20:59] <pja> right
[20:59] <pja> theres my big question
[20:59] <dmick> so why would rados have to know where they are?
[21:00] <pja> when rados does not know it
[21:00] <pja> how does it apache?
[21:00] <dmick> I don't know what that question means
[21:00] <pja> ssl module activated - okay
[21:01] <pja> but you have to say a vhost where the certificates are
[21:01] <pja> .
[21:01] <pja> when you host a website
[21:01] <pja> you say in the virtualhost
[21:01] <pja> *:443
[21:01] <pja> sslengineon
[21:01] <pja> sslcertificatefile /var/www/ssl/apache.key
[21:01] <pja> apache.crt, sorry
[21:02] <pja> and also sslcertificatekeyfile ....apache.crt
[21:02] <pja> ------
[21:02] <pja> but here is nothing like that
[21:02] <dmick> I don't know. This sounds like an Apache configuration question, though, and nothing to do with RADOS or radosgw

[21:04] <pja> yes it has
[21:04] <pja> that is my big question
[21:05] <pja> you said before "rados doesn't do SSL, Apache does "
[21:05] <pja> so it has to be configured in apache
[21:05] <pja> when you look here:
[21:05] <pja> http://ceph.com/docs/master/radosgw/config/
[21:06] <pja> theres only a virtualhost for port 80
[21:06] <pja> no word about adding something like ssl engine
[21:06] <pja> dont you use ssl?
[21:06] <dmick> I'm missing the point about how this has anything to do with configuring radosgw
[21:06] <dmick> again: this is Apache configuration
[21:07] <pja> yeah but it has to do with rados
[21:07] <dmick> yes, the sample Apache config on Ceph's page is for http
[21:07] <pja> because i need apache for rados
[21:07] <dmick> not https
[21:07] <dmick> pja: yes, everyone understands that
[21:07] <pja> ahh ok, so i have to edit it
[21:07] <dmick> I suggest you read up on, or find help with, Apache configuration
[21:07] <pja> no sample config from you?
[21:08] <dmick> not that I know of
[21:08] <pja> the ceph/rados page is written detailed... and then no word about you have to edit the vhost

[21:09] <pja> for me its all a big question mark

[21:09] <pja> the connection point
[21:12] <pja> do you know boto?
[21:12] <pja> its a test programm for s3 api
[21:12] <dmick> I would suggest you could start testing this with http, but it seems like that would be obvious
[21:12] <pja> i installed it know
[21:12] <dmick> and yes, we use boto

[21:13] <pja> there is a test script

[23:15] <loicd> I'm trying to figure out how to run https://github.com/ceph/ceph/blob/master/src/test/filestore/store_test.cc
[23:17] <nwat> I'm looking a bit at watch/notify/linger subsystem. I'm curious about how a watch is reestablished after a client loses connection. What identifier ties a watch to a client?
[23:17] <joshd> nwat: the cookie
[23:18] <joshd> nwat: and the connection state
[23:18] <loicd> when I run ./test_filestore it hangs ( the output is http://paste.debian.net/230258/ )

[23:21] <nwat> joshd: so connection failures are OK, but would a client crash then not be able to recover its watches?
[23:27] <gregaf> nwat: it wouldn't make any sense for it to do so
[23:28] <nwat> Well, I can see value in attaching a name to a set of watches and restablishing that watch by name.
[23:28] <gregaf> watch/notify just tells you that the object changed, but you have to read it on initial setup anyway so you'd get any previous changes

[23:28] <gregaf> huhwhat?
[23:28] <nwat> If a client doesn't need to see all operations
[23:31] <joshd> loicd: joao or sjust would know
[23:32] <gregaf> nwat: I'm not understanding your statements; I'm not sure if it's because you don't know how watch-notify works or if we're just on different wavelengths
[23:33] <nwat> my understanding of watch/notify.. a watch registers an interest in an object. a notify will synchronously broadcast a messages to watchers on an object. correct?
[23:34] <gregaf> right
[23:34] <loicd> joshd: ok. I'm investigating :-) Although it's gtest based and could probably run standalone, it belongs to bin_DEBUGPROGRAMS += test_filestore and should probably be called with arguments or a pre-defined context
[23:34] <gregaf> nwat: but there's no "set" of watches that the cluster can keep an eye on; a watch is attached to the object being watched
[23:35] <nwat> gregaf: got it, i was thinking a watch was more general than a single object. ok, i think that answers my question.
[23:35] <dmick> loicd: I don't know test_filestore, but I note the existence of test/filestore/run_seed_to.sh
[23:37] <nwat> gregaf: presumably this might be would be doable within a pg for users with custom locator keys
[23:37] <loicd> dmick: yes, and it relies on test_filestore_idempotent_sequence but I don't see that it calls test_filestore. Am I missing something ?
[23:38] * verwilst (~verwilst@dD5769628.access.telenet.be) Quit (Quit: Ex-Chat)
[23:38] <dmick> so it does, sorry about that. hum.
[23:38] <gregaf> nwat: not with any of our current implementation, although I guess if we really wanted to (but we really don't want to)
[23:39] <nwat> gregaf: ya.. but i've been staring at the ceiling a lot today
[23:39] <gregaf> heh

[23:53] <dmick> loicd: I can reproduce the hang, indeed
[23:53] <loicd> dmick: I'm glad it's not something from my environment, thanks for the confirmation ;-)
[23:56] <dmick> and running it again coredumps. wee.
[23:59] <loicd> dmick: yes but it's just because of the stale store_test_temp_dir and store_test_temp_journal if you remove them it will run and block again
