06:28 post-factum nigelb, latest regression tests failed for me because of (maybe) slave reboot. was that intentionally?
06:39 post-factum anyway, nigelb, hagarth, i've dropped a note to ML

07:04 misc post-factum: most likely not
07:04 misc post-factum: but that's the cloud :/
07:05 apandey joined #gluster-dev
07:06 post-factum misc, cloud should be about reliability, fault-tolerance, scalability, high availability and much more -abilities
07:08 misc post-factum: well, jenkins should indeed retrigger jobs that failed due to builder disappearing, that would achieve HA
07:08 misc I am not sure if it can, and I guess it happen much less than others failure so we never tought of that :/
07:09 post-factum tests are so painful
07:09 ppai joined #gluster-dev
07:11 atinm Folks, is there a way to negate an EXPECT_WITHIN just like 'TEST !' ?

07:41 post-factum now we have to merge http://review.gluster.org/15603 in order to have tests passed :/
07:41 nbalacha joined #gluster-dev
07:42 mchangir joined #gluster-dev
07:45 misc mhh, so I see that dbench fail on a regular basis
07:45 misc what does dbench do ?
07:45 misc and can we disable the tests for now, since it has been broken since 2 weeks ?
07:47 post-factum nigelb, ^^
07:47 * post-factum doesn't know what that is
07:47 misc a load tester used as part of the glusterfs test suite
07:48 misc https://bugzilla.redhat.com/show_bug.cgi?id=1379228
07:48 glusterbot Bug 1379228: unspecified, unspecified, ---, bugs, NEW , smoke test fails with read/write failed (ENOTCONN)
08:05 nigelb morning
08:08 nigelb post-factum: that one is definitely weird.
08:08 nigelb I suspect rackspace networking had a blip.
08:09 nigelb which has happened to me in previous jobs with rackspace networks.
08:09 nigelb misc: Can we give our builder1 and builder2 more CPU?
08:09 nigelb I'm curious if the random failures are due to time issues which stem from a not powerful enough machine.
08:17 misc nigelb: like a faster cpu, no, another vcpu, yes
08:18 itisravi joined #gluster-dev
08:20 nigelb misc: another vcpu, yes :)
08:21 misc let's try cpu hotplug
08:21 skoduri joined #gluster-dev
08:23 post-factum dont plug that plug... boom!
08:24 misc so I did plugged 2 cpus on builder1
08:25 misc and it doesn't answer to ssh anymore
08:26 kdhananjay joined #gluster-dev
08:26 misc and ... same for builder2
08:26 * misc sigh
08:26 nigelb Heh
08:26 nigelb needs a reboot?
08:26 misc yeah
08:26 misc I susopect either 2 vcpus hit a race condition
08:26 misc or centos 6 is not hotplug aware
08:27 nigelb I need to finish the gerrit upgrade plans and announce it.
08:27 misc (also, the only way I found was with virt-manager)
08:29 nishanth joined #gluster-dev
08:29 riyas joined #gluster-dev
08:35 pranithk1 joined #gluster-dev
08:37 post-factum misc, i told you, boom
08:39 misc post-factum: indeed
08:39 misc nigelb: also, adding 1 more cpu is gonna help onloy if we add one more process to use it
08:40 nigelb misc: Oh.
08:40 nigelb Maybe I should add more RAM.
08:41 misc nigelb: I can take a look once I am in the office
08:41 karthik_us joined #gluster-dev
08:44 k4n0 joined #gluster-dev
08:45 nigelb pranithk1: I'm reasonably confident your key isn't correctly formatted.
08:45 nigelb I can't ssh with my key if I have your key in authorized_keys
08:46 magrawal joined #gluster-dev
09:05 nigelb misc: When you have time today, there's a bunch of review requests against build-jobs.
09:10 ndevos nigelb, misc: I think 2GB was the least amount of RAM that made the tests function correctly
09:11 nigelb It already has 2GB.
09:12 nigelb I suspect that 2GB rackspace machine != 2GB machine in our racks.
09:12 ndevos it probably also depends on what other processes are running, and what (virtual) hardware is available
09:13 nigelb There's really nothing else running.
09:13 nigelb It's a physical machine with two VMs.
09:13 nigelb One of which is actively being used as a test machine. The other one isn't.
09:21 pranithk1 nigelb: I use that for gerrit/github...
09:31 nigelb pranithk|afk: yeah, that was my fault. The .ssh folder had the wrong permissions.

16:02 raghu` dlambrig_: Nope. I am not Du. I am the other raghu :)
16:03 kkeithley not to be confused with Talur, aka rastar
16:04 pranithk1 joined #gluster-dev
16:05 raghu` kkeithley: Ha ha yes.
16:06 dlambrig_ kkeithley: Niels answered it.. apparently RCU is needed wherever we run glusterd.. so I guess it is available on OXS and BSD as well as RHEL6
16:11 kkeithley Yes, on OS X you can get it from Homebrew.
16:11 kkeithley It must be in FreeBSD and NetBSD too
16:11 kkeithley /in/available for/
16:12 dlambrig_ do you (or maybe someone reading) know what performance boost we got from RCU in gluster
16:12 jiffin joined #gluster-dev
16:13 kkeithley I think shyam knows
16:14 shyam RCU and the resultant perf boost, I do not have data on that specifically, older threads from KP (krishan parthasarathi) or Kaushal may shed better light.
16:15 shyam RCU was for glusterd, so I am not sure a perf boost was even measured (i.e for management operations), I do not think it appears in the IO path
16:16 dlambrig_ hm, glusterd would not sound like a great use case for RCU. The IO path was what I was looking for.
16:17 kkeithley we switched to epoll for IO path perf boost
16:17 ira threaded epoll...
16:17 ira epoll, as I remember.
16:27 msvbhat joined #gluster-dev
16:41 shyam yup, (multi)threaded epoll in the IO for performance (one of the (possibly) 3 things we did over some time)
