07:07 mchangir nigelb, why aren't freebsd-smoke and netbsd6-smoke running on the release-3.8 branch? or am I missing anything?
07:13 nigelb I don't think it's been configured to run anywhere but master
07:13 mchangir nigelb, they on release-3.7 though
07:13 * atinm echoes the same
07:14 atinm http://review.gluster.org/#/c/14844/ FYR
07:14 nigelb Looks like we missed the step where it has to be configured for 3.8 as soon as it's released.
07:14 nigelb File a bug, please?
07:14 mchangir nigelb, okay
07:15 mchangir nigelb, what should be the BZ component?
07:15 nigelb project-infrastructure
07:15 mchangir okay
07:16 mchangir I should file the BZ against glusterfs mainline project right ?
07:16 nigelb yep
07:19 mchangir nigelb, https://bugzilla.redhat.co​m/show_bug.cgi?id=1357782
07:19 glusterbot Bug 1357782: unspecified, unspecified, ---, bugs, NEW , smoke: freebsd-smoke and netbsd6-smoke tests not running on release-3.8 branch
07:25 mchangir nigelb, ndevos, we should have project phase readiness checklists maintained in a google spreadsheet ... it'll make life a bit easier and spare our brains of the task of recollecting and coordinating such mundane activities
07:27 Bhaskarakiran joined #gluster-dev
07:30 nigelb mchangir: you can recheck smoke now. ndevos, would it be okay to run smoke on all the branches?
07:30 nigelb That way we don't even run into this trouble in the future.
07:48 post-factum atinm: spammed you with more coredumps on BZ #1353561
07:48 post-factum atinm: let me know if you need more info
08:00 prasanth joined #gluster-dev
08:20 gem joined #gluster-dev
08:39 atinm post-factum, will check
08:40 post-factum atinm: thanks
08:51 pranithk1 joined #gluster-dev
08:55 pranithk1 nigelb: https://build.gluster.org/job/rackspace-n​etbsd7-regression-triggered/18159/console is stuck...
08:55 pranithk1 nigelb: I am thinking of retriggering the task, but wanted to know if you want to take a look at it
08:57 nigelb pranithk1: It just started 4 mins ago... give it another 2 mins to see if it's actually stuck?
08:57 nigelb Ahhh
08:57 nigelb 5h ago.
08:58 pranithk1 nigelb: yeah :-)
08:59 nigelb I see what's wrong.
08:59 nigelb Let me take care of it.
09:00 pranithk1 nigelb: cool, let me know...
09:02 nigelb pranithk1: job killed
09:05 nishanth joined #gluster-dev
09:09 devyani7_ joined #gluster-dev
09:11 pranithk1 nigelb: thanks.. did you find why this happened?
09:11 nigelb Yeah, there were leftover gluster processes.
09:11 atalur joined #gluster-dev
09:11 nigelb I rebooted the machine and it's much better now.
09:13 gem joined #gluster-dev
09:18 ndevos nigelb: yeah, I think all smoke tests should run on 3.8 too, it we broke it, we'll need to fix it again
09:19 ndevos mchangir: instead of a google doc, it should probably be listed on http://gluster.readthedocs.io/en/latest/Con​tributors-Guide/GlusterFS-Release-process/
09:21 nigelb ndevos: I'll change smoke to run on all branches then.
09:21 nigelb Does that sound better?
09:21 nigelb Instead of naming branches with PLAIN, I'll do PATTERN, **
09:22 nigelb Or is it called ANT in the XML, I don't remember.
09:22 nigelb misc: I have some success in getting ping working on netbsd with ansible.
09:22 nigelb I'm hoping I can give you a pull request to do basic setup on netbsd eventually.
09:25 ndevos nigelb: sound good to me, I think the 3.6 branch is excluded in the script itself, and just always returns success?
09:26 nigelb I'll dig before I make a change.
09:26 nigelb May not be true for the package building, etc.
09:26 msvbhat joined #gluster-dev
09:26 nigelb I'm hoping that I whip netbsd into some sort of stable shape today.
09:32 hgowtham joined #gluster-dev
09:33 misc nigelb: well, ping work right from the start
09:33 misc nigelb: the problem is applying any change
09:33 nigelb misc: yeah, I hadn't gotten to the ping part ever.
09:33 misc mhh
09:33 nigelb Because I didn't have ssh keys in there.
09:33 nigelb and I had that auth problem.
09:33 misc ok, that was something that could be fixed
09:34 misc also, the server are ready so if you want to install VM and/or images there
09:34 nigelb I'm rebuilding the server I killed with rm -r
09:34 nigelb \o/
09:35 nigelb misc: what are the specs? :)
09:36 misc nigelb: 128G of ram, around 40 cpu, and 25T of disk for VM
09:37 misc (in raid 5, so the disk is freaking fast)
09:38 nigelb We should make a list of priorities
09:38 nigelb and see what goes in there first.
09:38 misc well, what is currently blocking the community ?
09:39 nigelb That depends on who you ask :)
09:39 msvbhat joined #gluster-dev
09:40 nigelb I'd love to see 1) better monitoring, 2) staging for jenkins/gerrit, 3) CI machines move in cage
09:40 nigelb CI machines = A pool of centos and netbsd machines. Or at least centos machines to being with
09:42 misc what I would like to see if moving gerrit/jenkins to the 2 new servers, and then that we can move ye old one in the other side of the cage
09:43 misc and move stuff out of rackspace to the point it cost us less money
09:43 misc (but still keep stuff there for redundancy purpose)
09:43 misc nigelb: I also think it will be easier to operate netbsd in VM rather than in cloud
09:43 misc even if the problem is the lack of cloud image
09:44 nigelb I'm okay with this plan
09:45 nigelb misc: I'm seriously contemplating experimenting with zuul and nodepool.
09:45 nigelb Just for gating, at least.
09:45 misc nigelb: => software factory ?
09:46 nigelb hrm?
09:46 nigelb Also, brb. I need to step out for 30 mins.
09:46 misc mhh let me find
09:46 misc https://github.com/redhat-cip/software-factory
09:52 atalur joined #gluster-dev
09:55 atinm post-factum, I think you should reach out to pranithk1 or raghug for BZ 1353561
09:59 post-factum atinm: i see pranithk1 added himself to bz :)
09:59 post-factum atinm: and kotreshhr as well
09:59 pranithk1 post-factum: Is it consistent?
10:00 post-factum pranithk1: you mean, if i could reproduce it reliably?
10:00 pranithk1 post-factum: yeah
10:00 post-factum pranithk1: yes, each time
10:01 pranithk1 post-factum: Except Kaleb's build patch, my patch about logging, rest seem related... I have lower doubt on the patches by Raghavendra G
10:02 post-factum pranithk1: i tried to reverted them with no luck
10:02 post-factum pranithk1: at least "storage/posix: fix inode leaks"
10:03 pranithk1 post-factum: Does this happen on stock 3.7.13?
10:03 post-factum pranithk1: we do not use stock builds becasue of memory leaks :(
10:04 pranithk1 post-factum: oh do you mind trying on a test setup may be?
10:04 pranithk1 post-factum: If you don't have that luxury I will have to take a deeper look
10:05 post-factum pranithk1: yep, I could do that, but a little bit later. I have no pure test setup, and will have to downgrade one of production clusters for that
10:06 pranithk1 post-factum: hmm... that is bad. Let us know if you can try some things on a test cluster. Otherwise we will have to take a look all the new patches and see which can cause these problems.
10:07 post-factum pranithk1: i doubt those patches are related to the issue becasue the crash happened on 3.7.11 and 3.7.12 as well
10:07 post-factum pranithk1: as of that moment, the only patch unmerged was "changelog/rpc: Fix rpc_clnt_t mem leaks", but i tried to revert it as skoduri asked me, and no luck as well
10:09 pranithk1 post-factum: Now you are talking.
10:09 pranithk1 post-factum: So this is not because of those patches?
10:09 post-factum pranithk1: umm have i stated that before?
10:10 pranithk1 post-factum: Sorry didn't get your question :-(
10:10 atalur joined #gluster-dev
10:11 post-factum pranithk1: let me rephrase. yes, i think, the issue is not related to those patches, because 3.7.11 crashed without them as well
10:11 pranithk1 post-factum: okay cool.
10:12 pranithk1 post-factum: "Given distributed-replicated volume (we didn't test other layouts) multiple brick processes could crash under load while probing brick TCP ports." what is the meaning of probing here?
10:13 post-factum pranithk1: the prehistory of this is that we set up gluster bricks monitoring with zabbix
10:13 post-factum pranithk1: zabbix probes for opened tcp ports
10:13 post-factum pranithk1: and then crashes began to happen
10:14 post-factum pranithk1: to reproduce tcp port probing i use nmap now becasue zabbix is pretty slow to trigger the crash as it probes port once per minute or so
10:14 pranithk1 post-factum: How do they probe for open tcp ports?
10:14 post-factum pranithk1: i guess tcp handshake + close
10:14 pranithk1 post-factum: Do they send any data?
10:14 post-factum pranithk1: no, no data
10:14 pranithk1 post-factum: Oh so the connection will happen on it?
10:14 pranithk1 post-factum: So the rpc-transport could have been already created.
10:15 post-factum pranithk1: I guess, if you need some details on how probing happens, we could take a look at nmap
10:15 post-factum pranithk1: i use this: nmap -Pn -p49168-49172 127.0.0.1
10:16 post-factum pranithk1: https://nmap.org/book/man-po​rt-scanning-techniques.html
10:17 post-factum pranithk1: This technique is often referred to as half-open scanning, because you don't open a full TCP connection. You send a SYN packet, as if you are going to open a real connection and then wait for a response. A SYN/ACK indicates the port is listening (open), while a RST (reset) is indicative of a non-listener.
10:19 pranithk1 post-factum: okay. Raghavendra is more knowledgeable about these things. I will talk to him once he is available.
10:19 post-factum pranithk1: ok, ping me whenever you need more info
10:19 pranithk1 post-factum: yeah
10:22 nigelb misc: that looks like a good idea on paper.
10:22 nigelb I wonder if we can migrate with our existing data.
10:23 nigelb We don't really need all of it though.
10:26 misc nigelb: the good idea is that they provides a VM image, and I can use the almight hammer  of fixing bugs on them since they are usually in paris :p
10:26 misc but going to lunch
10:27 nigelb I couldn't run that errand. I need to try again in 30 mins.

10:30 nigelb ndevos: netbsd7 is back online.
10:30 nigelb It had a few gluster processes running amok.
10:31 ndevos nigelb: oh, didnt know it was gone?
10:32 nigelb Oh, you'd emailed about netbsd7
10:32 nigelb Gah.
10:32 nigelb err netbsd0
10:37 devyani7_ joined #gluster-dev

10:41 nigelb The git checkout being hung bit
10:43 ndevos ah!
10:48 nigelb anyway
10:48 nigelb I've been looking at these machines for 2+ weeks now
10:48 nigelb I have a hang of them now.

11:08 anoopcs ndevos, aravindavk : I have something to say on review.gluster.org/#/c/14892/. By default where will the service files get installed?
11:08 anoopcs If I don't give any prefixes.
11:08 aravindavk anoopcs: /usr/local*
11:09 anoopcs aravindavk, But we don't have /usr/local/lib/systemd/system, right?
11:09 aravindavk anoopcs: will be created by "make install"
11:10 anoopcs Really?
11:10 aravindavk anoopcs: yes, when you say "systemd_DATA" in make file, it will create directories required
11:11 anoopcs aravindavk, Oh..Ok.
