10:08 kshlm ndevos, You around?
10:08 * ndevos _o/ kshlm
10:09 kshlm Have you been able to log-in to ci.centos.org slave machine?
10:09 kshlm Brian had said the information would be available on the jump server, but I don't have it.
10:10 ndevos kshlm: on the jump server there should be a file in the homedir with login details
10:10 zhangjn joined #gluster-dev
10:10 ndevos kshlm: oh, wait, maybe not on the jump server, but on slave01.ci.centos.org
10:10 ndevos [storage-sig@slave01 ~]$ ls
10:10 ndevos duffy.key  jenkins.creds
10:11 ndevos and those files are there for the gluster user on slave01 too
10:11 kshlm Is the user gluster@slave01?
10:12 ndevos yes
10:12 ndevos we have two users, "gluster" for upstream, and "storage-sig" for, guess what, the Storage SIG
10:12 kshlm I'm being asked for a password for gluster@slave01
10:12 ndevos you should be able to use your ssh-key, I think?
10:13 ndevos kshlm: your kaushal@arch key is in authorized_keys (2 of them even)
10:14 kshlm I need to tunnel?
10:14 kshlm I was trying logging in from the jump server.
10:14 ndevos yes, login on jump.ci.c.o and from there to slave01
10:14 rafi joined #gluster-dev
10:14 ndevos or setup your ssh client to automatically setup the tunnel
10:17 shubhendu joined #gluster-dev
10:19 kshlm ndevos++ I was able to login.
10:19 glusterbot kshlm: ndevos's karma is now 235
10:25 kshlm ndevos, the given jenkins credentials seem to be wrong. I'm not able to login to ci.centos.org as the `gluster` user.
10:25 ndevos kshlm: hmm, I'm pretty sure they worked before, let me try
10:27 ndevos kshlm: indeed, does not work for me either, but it does match what I have in my password manager, hmm
10:31 kshlm ndevos, I'll check with Brian once he's online later.
10:31 ndevos kshlm: maybe someone changed the password through the Jenkins webui? could you send an email to all participants and ask?
10:31 kshlm ndevos, I will.
10:32 ndevos kshlm: I can login as the storage-sig user, and there is an option to change the password...
10:36 ndevos kshlm: if you have a few minutes to spare, could you check this for me? http://thread.gmane.org/gmane.com​p.file-systems.gluster.infra/801 (Gerrit server in our Jenkins)
10:36 kshlm ndevos, that seems to be similar to the disconnections we have that requires jenkins restart.
10:37 kshlm BTW, why do you need a new server entry?
10:38 ndevos kshlm: the new server has different ssh/gerrit commands to pass "--label Smoke=.." instead of --verified
10:40 kshlm ndevos, couldn't you just select the label in jenkins?
10:40 ndevos kshlm: unfortunately you cant :-/
10:40 kshlm I've added all the available labels to the review.gluster.org server entry.
10:41 kshlm They should be available from the job pages now.
10:41 hgowtham joined #gluster-dev
10:42 obnox rastar: doesn't gluster use libcmocka nowadays instead of cmockery ?
10:42 ndevos kshlm: really, I do not think you can select them... I've updated https://build.gluster.org/job/smoke/configure to vote with an ssh-command, but that is very ugly
10:42 obnox oops, that's the point of that diff, ignore my Q
10:43 ndevos kshlm: if you know how to select the Smoke label in that job, please point out where I can find it
10:44 kshlm ndevos, even I'm not exactly sure about that. But I'll check and see if I can find how to do it.
10:45 ndevos kshlm: if a job can use a custom ssh/gerrit option, that would work too, but I could not find any [advanced] button that made it possble, so I tried the add a Gerrit server way
10:45 rastar obnox: yes, that is why I removed cmockery from pre-baked vm
10:45 rastar obnox: and install cmocka
10:46 obnox rastar: why is it on the pre-baked vm in the first place
10:46 rastar obnox: I had created it before you pointed out that we don't use cmockery anymore
10:47 obnox ah... then rather update the pre-baked vm, right? ;-)
10:47 rastar obnox: and I am lazy to update the box for now for just one change
10:47 obnox heh, ok
10:47 rastar obnox: will do after getting a bit more feedback
10:48 obnox rastar: it's fair enough for a start
10:49 obnox rastar: i'd like to learn how you create the box
10:49 obnox (at some point)
10:49 rastar obnox: I will record a session/write a box. It is currently a scratch text file of instructions/commands on my laptop
10:50 rastar *write a blog
10:52 rafi joined #gluster-dev
10:54 ndevos kshlm: others seem to want to set different labels too, and current solution seems to boil down to adding Gerrit servers - http://stackoverflow.com/questions/27982​027/jenkins-gerrit-multiple-builds-with-​different-labels-from-one-gerrit-event
10:56 obnox rastar: ok

13:22 ndevos skoduri, kkeithley: how about added a BIG FAT WARNIN in the nfs.log when mounts on localhost are done?
13:23 ndevos warnin+G
13:23 kkeithley o_O why?
13:24 skoduri ndevos, do you mean log capturing clients info ?
13:24 ndevos because mounting over localhost does not work with NFSv3 - need to disable locks and all
13:25 ndevos skoduri: yeah, so that when we ask users to attach the logs, we (and they) can immediately see that the issues might come from that
13:28 kkeithley sorry, I was thinking ganesha.  You mean gnfs
13:28 ndevos well, ganesha has the same troubles for NFSv3...
13:29 skoduri ndevos, okay..I am not sure how straightforward the change will be.. do we need in rpc layer or nfs?
13:30 skoduri sorry mount should take care of it..
13:30 ndevos skoduri: I have not thought that much about it yet, but it should be possible to handle when a MNT request comes in, there is permission (ip/host) checking there
13:30 skoduri right
13:31 skoduri that reminds me ndevos today we ran into a strange issue where mount command on one particular client is failing but the same volume mount succeeds on another client
13:31 skoduri and there are no log messages in nfs.log
13:31 skoduri pkt trace shows that MNT NULL request reached the server but there is not response
13:32 skoduri I haven't debugged further but any idea what could be the issue?
13:32 zhangjn joined #gluster-dev
13:32 ndevos hmm, no, I havent heard of something like that before, where was the pkt trace captured?
13:34 skoduri on the client side
13:35 skoduri http://fpaste.org/311968/14531240/
13:35 pranithk joined #gluster-dev
13:38 pranithk rastar: I don't see submit button for this patch http://review.gluster.org/#/c/13196, Am I missing something?
13:38 pranithk ndevos: ^^
13:38 ndevos pranithk: in the upper left corner it says "Needs CentOS-regression"
13:38 pranithk ndevos: Ah!
13:39 pranithk ndevos: CentOS regression runs what all?
13:39 ndevos pranithk: maybe regression testing has not finished yet?
13:39 pranithk ndevos: okay
13:39 ndevos pranithk: yeah, it is the standard regression tests that were doing Verified=+1, the label only got renamed
13:40 pranithk ndevos: got it!
13:41 ndevos pranithk: it seems regression testing only just got started - https://build.gluster.org/job/rackspace​-regression-2GB-triggered/17659/console
13:41 pranithk ndevos: okay :-)
13:41 ndevos pranithk: ah, thats probably when you gave it +2?
13:41 pranithk ndevos: could be :-)
13:42 kkeithley speaking of bugs, does https://bugzilla.redhat.co​m/show_bug.cgi?id=1293798 (nfs-ganesha + tiering) look at all related to the other ganesha+tiering bugs we've had?
13:42 glusterbot Bug 1293798: unspecified, unspecified, ---, kkeithle, NEW , While performing rm -rf getting unknown error 527 on tiered volume
13:43 ndevos skoduri: I'm not sure what to make out of that trace... sorry
13:43 ndevos skoduri: MNT NULL was sent, and the nfs server gave a reply, after that <nothing>
13:44 skoduri ndevos, NFS server hasn't sent reply
13:44 skoduri ndevos,  I shall check with some debug points and update
13:44 ndevos skoduri: on line 51 there is an ACK, well, part of the tcp-handshake, and the client should pickup after that
13:45 ndevos uh, line 52
13:45 skoduri but that's not response from nfs-server right..it is just TCP packet ACK
13:46 skoduri is you see 32, 33
13:46 skoduri aftr TCP ACK NFS server sent response
13:47 ndevos kkeithley: that is not a community gluster bug?
13:47 kkeithley well, there isn't a community bug yet. ;-)
13:47 skoduri kkeithley, and its gNFS bug not ganesha
13:48 skoduri kkeithley, do not recollect any other simialr bug
13:48 ndevos skoduri: oh, right, [ack] is replied, and then a reply with the data
13:48 kkeithley boy, I really can't read at 11:30 at night. Or 8:30 in the morning.
13:49 skoduri :D ..
13:49 ndevos skoduri: is that reproducible? how about capturing a tcpdump on the server-side as well (both at the same time), and compare them?
13:49 skoduri ndevos, yeah will try.. not sure if reproducible but I have requested to keep the setup as is..
13:50 ndevos kkeithley: "Volume is disabled: " is rather a clear error message, but no idea how that could be only related to tiering
13:50 skoduri ndevos, kkeithley have to leave now..catch you tomorrow :)
13:51 ndevos cya skoduri!
13:53 kkeithley ttyl
13:53 zhangjn_ joined #gluster-dev
13:53 ndevos kkeithley: btw, comonent=glusterfs, subcomponent=nfs would mostly be for nfs-ganesha, I think? component=gluster-nfs otherwise
13:54 kkeithley heh. Yeah, when I looked at it last night I really wasn't paying close attention to the details.
