armaanfolks, which service should have access to backup_ceph_conf file14:33
*** markvoelker has joined #openstack-cinder14:34
*** eharney has joined #openstack-cinder14:34
jbernardarmaan: cinder-backup14:44
armaanjbernard: ah, so no need to put ceph.conf in controllers where cinder-api is running14:45
jbernardarmaan: that depends on your deployment14:46
armaanjbernard: I am using two ceph clusters and the backup_ceph_conf is different from the one in /etc/ceph14:46
jbernardarmaan: and what you mean by access, are you referring to posix file permissions, or cephx auth?14:46
jbernardarmaan: i presume c-bak is running on the controller?14:46
armaanjbernard: Interesting, i need to check again because i think i saw cinder-back on compute nodes14:47
armaanjbernard: by access i mean somehow cinder-back should know where to find the ceph.conf which is different from what is present in /etc/ceph14:49
jbernardarmaan: yes, if it's not in the default location then your config must reflect that accordingly14:49
jbernardarmaan: if you run the serivce with debug enabled, the init phase /should/ indicate some of the possible misconfigurations14:50
armaanjbernard: just confirmed, cinder-backup is running in compute nodes14:50

gansojungleboyj: ping14:51
armaanjbernard: should it be owned by cinder14:52
andreas_sHi, was the final os-brick release already cut? Or is there still a chance to get a patch landed? In particular this one https://review.openstack.org/53539614:52
andreas_sshould be a low risk patch, as it's only touching s390x specific code..14:53
jbernardarmaan: that file must be readable by the user of which the cinder-backup process is executing14:53
armaanjbernard: ok, so this should do "chown root:cinder /root/ceph.conf"14:53
smcginnisandreas_s: The non-client library freeze, which include os-brick, was last Thursday.14:53
smcginnisandreas_s: That will need to wait for Rocky to open up.14:54
jbernardarmaan: you could, but i cannot advise on file contents and permissions on your server14:54
andreas_ssmcginnis: oh dear, missed it by one week. Ok thanks14:54
jungleboyjganso:  Pong.14:55
*** zhaochao has quit IRC14:56
jbernardarmaan: also worth considering, c-bak can consume conderable amounts of both network and cpu, so it may be wise to run it on a not-compute node(s)14:56
gansojungleboyj: could you please review https://review.openstack.org/#/c/537664/1 ?14:56
armaanjbernard: thanks, that is very valuable info14:56
jungleboyjganso:  Sure.  Looking.14:57
*** alexchadin has quit IRC14:57
gansojungleboyj: thanks!14:58
armaanfolks, i just installed cinder-backup and it is running on compute nodes. The cinder community recommends to run the c-bac  on non compute nodes because it can consume a lot of cpu & network14:58
armaansorry, wrong channel14:58
*** yangyapeng has joined #openstack-cinder14:59
jbernardarmaan: it really depends on resource availability and allocation, but it's something to consider14:59
jbernardarmaan: no problem14:59
armaanjbernard: I would not want to run it on compute nodes as well. Just wrote that message in the OSA channel. They may want to move the service to controller nodes15:00
*** r-daneel has joined #openstack-cinder15:02

Swansontobasco, I have not seen that. What is happening on the SC?17:27
tpsilvathis pcre failure is affecting all 3rd party CIs17:27
jungleboyj:-(17:28
tobascoSwanson: I don't think it's the SC per say, it maps to the proper hypervisor node, cinder says all attachments is correct, it's just iscsi/multipath mounting the same LUN for some with /dev/disk/by-path and some for md in /dev/mapper17:31
*** jessewu1 has quit IRC17:31
tobascoi.e "source dev" in libvirt.xml is the same /dev/disk/by-path or /dev/mapper if it's a multipath device17:32

Swansontobasco, I'm not much help for that. Nova folk, maybe?17:33
*** jessewu1 has joined #openstack-cinder17:34
tobascoSwanson: would cinder-volume being down when a hypervisor is rebooted and instances starting cause issues, because it's on the same node17:34
Swansontobasco, I'm not certain. I know it isn't good.17:36
*** abhishekk has joined #openstack-cinder17:37
*** itlinux has quit IRC17:38
SwansonWe present the volume. If nothing has changed that should be fine. I think when cinder-volume starts up it re-maps everything and the SC doesn't pick a specific lun so it might map to a new one.17:38
SwansonSo, yeah, it could definitely could be the cause.17:38

geguileoerlon_: I don't understand the removal of the clone method thingy18:02
erlon_geguileo, the thing here is, that method uses the max_over_subscription_ratio to make calculations, every time before cloning a volume to a pool18:04
erlon_geguileo, but, today we already do that in the scheduler18:05
erlon_geguileo, let me find the patch18:05
geguileoerlon_: oh, I see, it would calculate if it fits based on the ratio the other volumes are using, right?18:05

imacdonnIf anyone's running volume driver CI with Jenkins, please let me know .. would like to see what you're using for Gerrit Trigger config20:16
rajinirsrc/pcremodule.c:32:18: fatal error: pcre.h: No such file or directory20:19
imacdonnrajinir: wrong channel? ;)20:20
Roamer`imacdonn, this is what I have: http://paste.openstack.org/show/653496/20:20
rajinirerlon_ mentioned about the pre thirdparty CI error , imacdonn20:20
Roamer`ah hell, and I was so caught up with our Nova driver being merged that I hadn't looked at our CI for hours now20:21
imacdonnRoamer`: Interesting ... aren't we supposed to trigger on "recheck" too?20:22
Roamer`rajinir, you're right, we're hitting this too20:22
erlon_rajinir, hey, rajinir, so yes, that error is happening, we couldn't get to the bottom of the problem20:22
Roamer`hm20:22
Roamer`I'll take a look... I'd guess it's a new dependency added somewhere20:22
rajinirRoamer, erlon_, we are hitting this too, thanks20:23
Roamer`imacdonn, not really, no.  Best practice now is to have "recheck" rerun the openstack.org Zuul test, and each CI has its own recheck trigger20:23
erlon_rajinir, we hacked our CI jobs to install liblpcre3-dev before each job20:23
erlon_so now we are working around that20:23
rajinirerlon_ thanks for the workaround, will try that20:23
Roamer`imacdonn, otherwise you can't trigger the rerun of a single third-party CI without triggering the openstack.org Zuul, too, which... takes time and on days like today is, erm, not really what you want :)20:23
imacdonnRoamer`: oh ... then I suppose this should be updated https://wiki.openstack.org/wiki/Cinder/tested-3rdParty-drivers#How_do_I_trigger_my_CI_to_rerun_on_gerrit_comments.3F20:24
Roamer`or hm, maybe I'm wrong about the best practice, but I've seen a couple of third-party CIs have their own recheck trigger... somebody will correct me if I'm wrong20:24
imacdonnsmcginnis jungleboyj ^^20:24
*** dustins has joined #openstack-cinder20:25
mmedvedeerlon_: with regards to liblpcre3-dev missing, I fixed it in our CI by installing everything from requirements/bindep.txt. I think it normally should include whatever dependencies are required20:25
imacdonnthanks for the regex anyway, Roamer` - that's helpful20:25
*** kaisers_ has quit IRC20:27
imacdonnRoamer`: regarding the recheck thing .. I think we're supposed to trigger on *either* "recheck" or "run-<custom name>"20:27
imacdonnRoamer`: So if we don't want a full recheck, we use the custom one in the comment20:28
erlon_rajinir, actually: libpcre3-dev20:29
Roamer`imacdonn, this actually makes a certain kind of sense, although it does lead to a mailbox filled with "yeah, yeah, sure, your change passed on our CI, too" when you just want to rerun the openstack.org Zuul...20:29
erlon_mmedvede, libpcre3-dev, forgive my bad spelling20:29
rajinirerlon_: yes, figured that20:29
rajinirthanks np20:29
erlon_mmedvede, that is the correct thing, but, now, Im not sure why our CIs weren't installing that20:30
imacdonnRoamer`: Ja. I think I'm going to try it with both, and see if the volume is manageable..... sure wish there was clear documentation on this stuff :/20:30
erlon_mmedvede, the libpcre3 is in the bindeps, since november, so, not sure why CIs or devstack or whatever is not installing things there20:31
erlon_mmedvede, where did added the fix? I mean where in your CI, job creation?20:31
mmedvedeerlon_: as early as possible when you already have pip and git available20:32
erlon_hmmm20:33
mmedvedeerlon_: in my case with jjb I have added a macro before the main job containing something like that (this is on apt system) http://paste.openstack.org/show/653498/20:33
erlon_mmedvede, hm, nice, didnt know about the bindep package, will add that to our fix, thanks20:35
