[17:03] <darkfader> *smile* during the ceph lab exercise one of the students ran a bonnie... that did not go too well :)
[17:03] <darkfader> but our slow network might have been an extra hurdle
[17:04] <darkfader> seems $boss has bought some 100mbit switches because they were cheaper...
[17:05] <elder> Hubs may be cheaper still.
[17:06] * fred__ (~fred@80-219-180-134.dclient.hispeed.ch) has joined #ceph
[17:06] <darkfader> oh well, some student gave a "D" rank for the equipment
[17:07] <darkfader> i think that'll get the message over lol
[17:07] <darkfader> and gceph constantly segfaults :(
[17:07] <darkfader> it would be really nice if it weren't broken
[17:11] <stxShadow> hmmm .... two crashes of ceph osd nodes today :S
[17:11] <darkfader> stxShadow: hehe, 3/7 went down on us after that bonnie run
[17:12] <darkfader> but i had warned them and explained why/how
[17:12] <stxShadow> i had something like this:
[17:12] <stxShadow> 2012-02-29 11:53:28.329296 7f8c4ed1d700 FileStore: sync_entry timed out after 120 seconds.

[17:12] <stxShadow> os/FileStore.cc: 2996: FAILED assert(0)
[17:13] <stxShadow> -> i could not end the osd process .... had to reboot the node twice
[17:14] <stxShadow> could someone explain, why hdparm is invoked at every restart ?
[17:14] <iggy> gceph?
[17:15] <stxShadow> no ...restart ceph with /etc/init.d/ceph restart ......
[17:15] <stxShadow> i get:
[17:15] <stxShadow> hdparm: sending ioctl 31f to a partition!
[17:15] <stxShadow> hdparm: sending ioctl 31f to a partition!
[17:15] <stxShadow> hdparm: sending ioctl 2285 to a partition!
[17:15] <stxShadow> hdparm: sending ioctl 2285 to a partition!
[17:15] <stxShadow> -> i use 3ware controllers
[17:16] <stxShadow> their answer to the request is:
[17:16] <stxShadow> 3w-sas: scsi0: ERROR: (0x03:0x0101): Invalid command opcode:opcode=0x85.

[17:16] <stxShadow> 3w-sas: scsi0: ERROR: (0x03:0x0101): Invalid command opcode:opcode=0x85.
[17:16] <iggy> that's a new debug thing after the fallout from someone figuring out guests with direct access to devices could do bad things
[17:16] <iggy> it's fairly safe to ignore if you are doing something where you expect that
[17:17] <stxShadow> ok ;) ....
[17:19] <darkfader> iggy: just a funny gui for end-users from what i saw
[17:19] <darkfader> but it is good at showing status
[17:20] <iggy> it's abandon ware from what I've seen
[17:37] <stxShadow> how can i get rid of the following inconsisteny:
[17:37] <stxShadow> 2012-02-29 16:08:52.586939 log 2012-02-29 16:08:42.608578 osd.2 10.10.10.14:6802/30882 4012 : [ERR] 18.5 osd.3: soid 8a5e37ad/rb.0.0.000000002b99/headextra attr _, extra attr snapset

[18:03] <fred__> sagewk, I don't know who is in charge with your tracker, but I used to be able to sign in using openid which doesn't work anymore, is it a known problem ?
[18:04] <sagewk> fred__: nope. let me check the settings
[18:05] <fred__> sagewk, got an "internal error" page displayed when being redirected back to your tracker from myopenid.com
[18:05] <sagewk> fred__: hrm
[18:13] <stxShadow> sagewk: any hint to the inconsistency above ?
[18:15] * stxShadow (~jens@p4FD060E4.dip.t-dialin.net) Quit (Quit: Ex-Chat)
[18:25] <fred__> sagewk, gotta go... if I can sign into your tracker tomorrow I'll create an issue to request a /etc/init.d/radosgw reload command that reopens new log file after log rotation
[18:26] <sagewk> fred__: k. i'm not anticipating spending time debugging redmine issues, but will ask around
[18:27] <fred__> sagewk, I understand, will look for reload command in future git commits and come back if it does not appear. Thanks!

[19:02] <Tv|work> whoa alex just carpet bombed us
[19:10] <joshd> sagewk: looks like the json_spirit stuff is causing problems with the deb gitbuilder

[19:42] <Tv|work> joshd: so it's not finding the header
[19:47] <Tv|work> i don't see anything putting the src/json_spirit in the include search path...
[19:47] <Tv|work> oh but the #include has json_spirit/ in it
[19:47] <Tv|work> so just src in search path should be enough...
[19:50] <Tv|work> so i'm guessing src/ is never in -I explicitly
[19:50] <Tv|work> and tends to work just because it's the cwd
[19:50] <Tv|work> but for mds/Resetter.cc, it's not
[19:50] <Tv|work> looking to verify that
[19:52] <Tv|work> oh except make doesn't recurse into src/mds, those are built with mds/foo paths while in src/

[21:20] <Tv|work> sjust: greatest value of "make distcheck" is "did i screw up and forget something"; it's hard to have make distcheck work and the release tarball not
[21:20] <Tv|work> sjust: for a project that releases tarballs, not having a successfull make distcheck is insanity
[21:21] <Tv|work> sjust: but i think porting leveldb to automake is the easiest way out, even if upstream refuses to accept it
[21:21] <Tv|work> i'll do that after lunch

[22:29] <gregaf> sagewk: umm, I assume I only have to care about the HEAD commit there
[22:29] <sagewk> yeah :)
[22:31] <gregaf> that's the only place that sets ms_addr, correct?

[22:33] <sagewk> the only possibility is accept() if someone randomly connects to us before the (learn and) publish our address. but they'll disconnect anyway because we won't be who they wanted.
[22:33] <sagewk> and in any case, we fix the bad port race still
