[20:04] <elder> Impossible.
[20:05] <elder> Maybe you're drowning, but you couldn't write that if you had already drowned.
[20:05] <elder> Please don't drown though.
[20:05] <nhm> elder: I could be drowning while writing this.
[20:05] <nhm> elder: and this too.
[20:05] <elder> But you didn't drown (yet).
[20:07] <nhm> elder: present tense vs past tense?
[20:07] <elder> Versus infinitive.
[20:07] <elder> Or wait, gerund?
[20:07] <josef> argh gerunds
[20:08] <josef> latin has come back to haunt me
[20:09] <elder> If you had said "latin is now haunting me" that would be using a gerund.
[20:09] <elder> I.e., gerunding.
[20:09] <josef> haha
[20:09] <josef> this is still more fun than enospc
[20:10] <Tv_> that just reminds me of "The major problem is simply one of grammar, and the main work to consult in this matter is Dr. Dan Streetmentioner's Time Traveler's Handbook of 1001 Tense Formations. It will tell you, for instance, how to describe something that was about to happen to you in the past before you avoided it by time-jumping forward two days in order to avoid it."
[20:10] <elder> You still can't avoid gerunds.
[20:11] <elder> But you might have subjunctive gerunds or something.
[20:11] <nhm> josef: Oh, I have about 450 new seekwatcher movies to look at. :S
[20:11] <josef> haha
[20:13] <nhm> elder: ext4 is beating xfs... Are you going to take that kind of abuse? :P
[20:14] <elder> You must be doing it wrong. :)
[20:14] <josef> i get that feeling all the time
[20:14] <josef> i run tests on ext4/btrfs/xfs and xfs gets stomped
[20:15] <josef> first thought is always that i did something wrong
[20:15] <elder> Well, you have to run your tests on Dave Chinner's machine. Then you're doing it right.
[20:15] <nhm> elder: actually, I was kind of hoping I was doing it wrong.
[20:15] <gregaf> Not if you aren't using the right configuration!
[20:15] <gregaf> isn't xfs approximately 17 different filesystems? :p
[20:16] <elder> Give or take 16.
[20:16] <nhm> josef: btrfs and ext4 are trading places a lot for me depending on the test config.
[20:16] <nhm> josef: (these are ceph rados bench tests)
[20:16] <gregaf> I'm just saying, with the number of allocation and logging strategies available...
[20:17] <nhm> gregaf: There's definitely a lot to tweak. But some random page on the internet told me the xfs devs know better than I do so I should just ignore all of that. ;)
[20:17] <josef> elder: rofl
[20:17] <josef> chris and i have had that exact conversation
[20:17] <josef> "you know if we ran this same test on daves box xfs would ruin us all"
[20:19] <nhm> btw, anyone here want to look at pages of graphs? It's only slightly less entertaining than looking at pages of blktrace output.

[21:39] <sjust> jmlowe: actually, it might be, one sec
[21:40] <sjust> it likely means out-of-order commits
[21:40] <sjust> was there any recovery happening on the cluster at the time?
[21:40] <jmlowe> I don't think so
[21:40] <sjust> hmm
[21:46] <sjust> did the client print any other logging?
[21:46] <nhm> josef: so late last week I took a look at the blktrace output from Sage's tests. btrfs-submit-1 seems to be jumping around a lot.
[21:46] <josef> it would, its the one that does all the bio submission
[21:47] <josef> theres an easy way to turn that off
[21:47] * josef lookds
[21:49] <jmlowe> not that I can find, just that in the /var/log/libvirt/qemu logs
[21:49] <sjust> ok
[21:50] <jmlowe> kind of a fluke, first time I've seen this
[21:50] <sjust> jmlowe: yeah, that's why I was excited :P
[21:51] <sjust> it means that the osd sent the commits out of order, and that's not supposed to happen. particularly without recovery happening
[21:52] <josef> nhm: actually it's not that easy
[21:52] <josef> nhm: if you want to do it yourself you can find everybody who does btrfs_wq_submit_bio() for writes and make them do the checksumming inline and then call btrfs_map_bio() with async_submit set to 0
[21:53] <josef> if you don't want to do it yourself i can write it up tomorrow for you to test with
[21:53] <josef> it will make some things slower but you'll be able to see where the ios are coming from
[21:55] <nhm> josef: Don't worry about it for now. Lets see what Sage has to say first since this has kind of been his project.

[21:56] <nhm> josef: I think he's out today or something.
[21:56] <josef> i have this handy dandy script that puts together a local ceph cluster for me now so if you have a script that reproduces the problem send it my way and i can look at it myself when i get free time (ha!(
[21:58] <nhm> josef: I think that test Sage ran was a workload generator Joao (and Sage?) wrote to try to mimic ceph IO.
[22:01] <nhm> josef: the actual writes I'm seeing during a rados bench run look like: http://nhm.ceph.com/movies/mailinglist-tests/btrfs-osd0-precise-3.4.mpg
[22:02] * maarten (~maarten@office.siteworkers.nl) has joined #ceph
[22:02] <nhm> precise + ceph 0.47.2 really improved things.
[22:02] <nhm> (and btrfs in 3.4 with -l 64k -n 64k)
[22:03] <josef> oh you are writing data right?
[22:03] <nhm> josef: yep
[22:03] <josef> this whole time i've been thinking it was a metadata only load
[22:03] <josef> ok well duh that makes sense
[22:03] * maarten (~maarten@office.siteworkers.nl) has left #ceph
[22:03] <josef> you have the metadata mirroring on
[22:04] <josef> so you are going to seek to write copy1 of metadata
[22:04] <josef> and then seek a short bit (couple hundred megs) and write copy 2
[22:04] <josef> and then seek up to hte data spot to write that
[22:04] <josef> the longer the test goes teh further the data area gets from the metadata
[22:04] * maje (~anonymous@office.siteworkers.nl) has joined #ceph
[22:05] <maje> hi
[22:05] <maje> i'm currently working with a test rados cluster
[22:05] <maje> and wondering what the best way would be to add metadata to the objects in the store
[22:05] <josef> hrm but then you start writing to earlier parts of the data range
[22:06] <josef> i'd be curious to figure out why that is happening
[22:06] <maje> i've seen tmap and xattr methods in the librados api
[22:06] <maje> xattr have size limitations of course based on the underlying filesystem
[22:06] <maje> are there any limitations on the tmaps?
[22:06] <nhm> josef: Well, I've got 150 sets of blktrace output from btrfs alone from this weekend to look at. ;)
[22:07] <nhm> josef: along with the corresponding seekwatcher movies. I'll try to get the movies at least posted.
[22:07] <gregaf> maje: no limitations on the use of tmaps
[22:08] <gregaf> but if you specify the right options, xattrs actually don't require the underlying FS either ??? sjust will know them
[22:10] <maje> gregaf: ok, any thoughts on what the use cases are for the xattr of tmaps?
[22:11] <maje> i presume tmaps are stored with the objects and also replicated?
[22:12] <gregaf> the original tmap interface was a way of using a single object as a key-value database, but that's what you used the whole object for
[22:12] * cattelan is now known as cattelan_away
[22:12] <gregaf> these days they're actually using a new "omap" interface, which sticks the keys and values into an integrated LevelDB store, and lets you keep using the object as well (and yes, the LevelDB stuff is replicated and moves with the object)
[22:13] <gregaf> since many filesystems have trouble with xattrs, we've also moved a lot of the use of "xattrs" to live inside that LevelDB
[22:13] <gregaf> so I'd use xattrs if you want a couple keys and values, or "tmap" if you want large lists of them
[22:13] <gregaf> *shrug*
[22:15] <sjust> gregaf,maje: you don't want to use tmap, use omap
[22:15] <maje> gregaf: excellent, that clarifies it a lot
[22:15] <gregaf> I thought it got automagically translated for librados users?
[22:16] <sjust> maje: as far as xattrs go, if you want to not store them as a fs xattr, it's better to use omap directly, it's implemented pretty much the same way
[22:16] <sjust> gregaf: only sort of, and only if you set the right flag in the config file
[22:16] <sjust> it's *much* easier to use the omap interface directly
[22:19] <maje> sjust: i'm looking at the api now, it does look a lot easier to use than the older tmap api
[22:20] <maje> thank you both, i'm going to look into it
[22:23] <Tv_> maje: just to say it explicitly: some fine day, both the "tmap" and the "xattr" stuff will probably go away, in favor of the omap style
[22:23] <Tv_> maje: because we have too many similar apis..
