| 16:25:41 | sean-k-mooney | if its not fixed ill flag it internally and see if i can find more info | |
| 16:26:03 | bauzas | clarkb: we're in a meeting but should be ended quickly in 5 mins hopefully | |
| 16:26:23 | bauzas | nothing to say more about stable branches ? | |
| 16:26:33 | bauzas | if not, let's move on and wrap this thing :) | |

| 16:29:29 | gibi | this was faaast | |
| 16:29:36 | clarkb | I didn't mean to interrupt the meeting, just wanted to point out that I don't think anything has been fixed on centos 8 stream yet. At least not if you look at the package git repos | |
| 16:29:45 | clarkb | maybe they can revert packages without going through git | |
| 16:30:09 | sean-k-mooney | clarkb: i think i miss read the mail thread | |
| 16:33:14 | sean-k-mooney | i tought ye had forced the mirror update in http://lists.openstack.org/pipermail/openstack-discuss/2022-January/026687.html | |
| 16:33:36 | sean-k-mooney | https://bugzilla.redhat.com/show_bug.cgi?id=2037807 is currently on qa | |
| 16:33:38 | bauzas | clarkb: oh my bad, missed the context | |
| 16:34:04 | bauzas | clarkb: that's the problems with the meetings in lieu of the regular IRC chan | |
| 16:34:12 | bauzas | we get interruptions often | |
| 16:34:23 | clarkb | sean-k-mooney: I think fungi had the impression that it was fixed upstream when it wasn't. As far as I can tell there has been no fix made upstream yet. | |
| 16:34:26 | bauzas | so I thought your ping was unintentional | |
| 16:34:30 | clarkb | bauzas: ah | |
| 16:34:46 | clarkb | I could've been more specific that I was referring to the centos 8 ping issues :) | |
| 16:34:55 | sean-k-mooney | clarkb: ya its still on qa so it has not been shiped yet in rhel and presumable not yet in centos stream | |
| 16:35:06 | bauzas | clarkb: but yeah, reading at what you wrote, this makes perfect sense this was on purpose :D my bad. | |
| 16:35:33 | sean-k-mooney | clarkb: the plue reuest seams to have been merged here https://github.com/redhat-plumbers/systemd-rhel8/pull/246 | |
| 16:35:44 | clarkb | sean-k-mooney: we want systemd-239-55 or newer or a revert on the iputils package aiui | |
| 16:36:11 | sean-k-mooney | yes http://pkgs.devel.redhat.com/cgit/rpms/systemd/commit/?id=a4b172eaddf0882435fd2eb4d146012db8e5a2f2 | |
| 16:38:05 | sean-k-mooney | https://git.centos.org/rpms/systemd/commits/c8s | |
| 16:38:12 | sean-k-mooney | its still on 239-54 | |
| 16:39:59 | sean-k-mooney | sorry for the confusion ill see if i can find someoen internally | |
| 16:51:11 | fungi | clarkb: sean-k-mooney: the mirror update i forced was for centos stream 9, because the official mirror we'd been copying from started refusing rsync connections on friday | |
| 16:51:27 | fungi | unrelated to the ping behavior | |

| 16:05:36 | opendevreview | Alexey Stupnikov proposed openstack/nova master: Support use_multipath for NVME driver https://review.opendev.org/c/openstack/nova/+/823941 | |
| 17:37:24 | spatel | Folks, i have glusterfs mounted on /var/lib/nova for my vms shared storage and everything working but when i delete my vm it didn't clean up files. i can still see disk and other file which taking lots of space. is that normal for nova | |
| 17:38:37 | sean-k-mooney | hum technially we dont support moutning /var/lib/nova on glusterfs however the shared file system support we have for mounting it on NFS shoudl work with it | |
| 17:39:10 | sean-k-mooney | the way we detect a shared files system is by touching a file which shoudl just work with any shared file system | |
| 17:39:25 | sean-k-mooney | in terems of deleting files | |
| 17:39:45 | sean-k-mooney | when you delete the vm it should delete the vm disk and other files in general | |
| 17:40:12 | sean-k-mooney | the backing files for hte guest image may stay in the image cache for a peiord of time but it will eventully get cleaned up | |
| 17:40:19 | sean-k-mooney | i wonder if this is liek the ceph issue | |
| 17:40:55 | sean-k-mooney | https://docs.openstack.org/nova/latest/configuration/config.html#workarounds.ensure_libvirt_rbd_instance_dir_cleanup | |
| 17:41:24 | spatel | hmm why did you say don't support glusterfs for /var/lib/nova ? | |
| 17:41:58 | sean-k-mooney | spatel: because we dont offcialy support or test that upstream | |
| 17:42:27 | sean-k-mooney | we test /var/lib/nova on nfs even thouhg we recommend using it | |
| 17:42:34 | spatel | but generally shared storage is storage just create file and delete file.. no matter who is in backend | |
| 17:42:42 | sean-k-mooney | but we have never offcially supprot clusterfs as afar as i recall | |
| 17:43:03 | sean-k-mooney | spatel: there are a buch of issue with locks and move operation that the latency of shared storage can cause | |
| 17:43:12 | sean-k-mooney | so in general we do not support it | |
| 17:43:19 | spatel | we have 800TB of glusterfs and it would be bad if i mount that on foo server and then mount on 50 compute nodes | |
| 17:44:07 | spatel | That is interesting... | |
| 17:44:12 | sean-k-mooney | in generall if you want ot use glusterfs with openstack the only supporte way to do it would via cinder | |
| 17:44:37 | sean-k-mooney | it can work the way you have it deplyed but its not a tested configuration and was never expiclty supported | |
| 17:46:06 | spatel | may be i am the first use case here.. :) i would still like to push it and try out because we already have large storage which i would like to use. | |
| 17:46:33 | spatel | if i see any issue (major issue) then i may switch to NFS | |
| 17:47:20 | spatel | If i go with cinder then its not going to be shared storage correct? does live migration will be supported with cinder base deployment? | |
| 17:48:07 | sean-k-mooney | spatel: well jsut a word of warning if we could remove support for this capablity entirly we would | |
| 17:48:25 | sean-k-mooney | we dont like support nfs backed /var/lib/nova | |
| 17:48:51 | sean-k-mooney | we only maintian supprot becasue we have some old large clouds that use it but this area fo the code is not activly maintained | |
| 17:49:03 | spatel | hmm! so in short no to shared storage except ceph. correct? | |
| 17:49:24 | sean-k-mooney | basically and even for ceph not by using cephfs | |
| 17:49:42 | spatel | ceph rbd | |
| 17:49:49 | sean-k-mooney | the probelm is that when using shared storate like this we are actully using a local storage driver in nova | |
| 17:50:06 | sean-k-mooney | e.g. image_type=qcow | |
| 17:50:07 | spatel | i know what you saying.. mounting nova on shared storage can have all kind of issue | |
| 17:50:31 | sean-k-mooney | and have sprincked some check in random parts of the code to do something else fi we detect its on shared storage | |
| 17:50:59 | sean-k-mooney | the main one come up aroudn move operations and evacuate | |
| 17:51:16 | sean-k-mooney | e.g. we need to make sure we dont overrie the image if we do a cold/live migration | |
| 17:51:36 | sean-k-mooney | and dont recreate it if we evacuate | |
| 17:51:42 | sean-k-mooney | to prevent loosing data | |
| 17:51:56 | spatel | hmm | |
| 17:52:22 | spatel | so what option i have in current design with glusterfs ? | |
| 17:52:36 | spatel | cinder boot volum? | |
| 17:52:43 | sean-k-mooney | if the sync time between writing a file on one host and reading it on another is long enough we might not detect its on shared storage whchi can be bad | |
| 17:52:58 | sean-k-mooney | cinder boot form vomue woudl work yes | |
| 17:53:19 | spatel | does cinder support glusterfs ? | |
| 17:53:23 | sean-k-mooney | what you are doign can work just be aware that there are dragons wehn you do this. | |
| 17:53:26 | sean-k-mooney | am it used too | |
| 17:54:08 | spatel | I understand this cluster not going to hold critical data. this is for crunch some data and give dynamic result | |
| 17:54:37 | sean-k-mooney | am its avaible for cinder backup | |
