Gluster issue with brick going down
by Chris Adams 22 Mar '22

22 Mar '22

I have a hyper-converged cluster running oVirt 4.4.10 and Gluster 8.6. Periodically, one brick of one volume will drop out, but it's seemingly random as to which volume and brick is affected. All I see in the brick log is: [2022-03-19 13:27:36.360727] W [MSGID: 113075] [posix-helpers.c:2135:posix_fs_health_check] 0-vmstore-posix: aio_read_cmp_buf() on /gluster_bricks/vmstore/vmstore/.glusterfs/health_check returned ret is -1 error is Structure needs cleaning [2022-03-19 13:27:36.361160] M [MSGID: 113075] [posix-helpers.c:2214:posix_health_check_thread_proc] 0-vmstore-posix: health-check failed, going down [2022-03-19 13:27:36.361395] M [MSGID: 113075] [posix-helpers.c:2232:posix_health_check_thread_proc] 0-vmstore-posix: still alive! -> SIGTERM Searching around, I see references to similar issues, but no real solutions. I see a suggestion that changing the health-check-interval from 10 to 30 seconds helps, but it looks like 30 seconds is the default with this version of Gluster (and I don't see it explicitly set for any of my volumes). While "Structure needs cleaning" appears to be an XFS filesystem error, I don't see any XFS errors from the kernel. This is a low I/O cluster - the storage network is on two 10 gig switches with a two-port LAG to each server, but typically is only seeing a few tens of megabits per second. -- Chris Adams <cma(a)cmadams.net>

all hosts lost scenario - restore engine from backup file - LOCKED HOST 4.3 version
by goosesk blabla 20 Mar '22

20 Mar '22

Hi, I have problem with LOCKED host after restore of engine. i am trying many disaster scenarios and one from them is loosing of all hosts with self hosted engine included with backup file of engine only. When all hosts and engine VM were destroyed at the same time, i installed new self hosted engine on hardware from one lost host. Then tried restore engine engine-backup --mode=restore --scope=all --file=backup/file/ovirt-engine-backup --log=backup/log/ovirt-engine-backup.log --no-restore-permissions --provision-db --provision-dwh-db –provision-reports-db After this, lost engine was restored successfully. I had offline Datacentrer, dead hosts and VM. I added new hosts, which were able to connect to domain storage automatically and I was able to start VM. New host cannot has the same IP as already dead host or hardware UID. This can be solved by setup old dead host to maintenance mode and then delete host. Then the same hardware and IP can be reused. But, host where old engine was running is LOCKED. You cannot migrate engine VM, cannot start hosted engine from new engine GUI, cannot setup host to maintenance mode and delete.. This is problem when your hardware for hosts is limited. I would like to ask how to solve this situation, Is there any way how to “reinstall” old hosts? I see that SSL certificates were changed with new installation of new hosts, but I don’t know if there is way how to enable old dead hosts. Is there any way how to destroy old engine VM to add host back to work ? Thank you

Hosted engine deployment fails with storage domaine error
by Eugène Ngontang 19 Mar '22

19 Mar '22

Hi, Hope you are well on your end. I'm still trying to setup a brand new hosted engine but I'm having "Hosted engine deployment fails with storage domaine error" issue, like shown in the screenshot. I can't figure out what's going on, I have checked the NFS server and everything seems to be working fine, as well as the nfs mount point on the client side (RHV host). Please can one here help moving fast with this troubleshooting? Any idea?

Re: mdadm vs. JBOD

Thanks to Nikolov and Strahil for the valuable input! I was off for a few weeks, so I would like to apologize if I'm potentially reviving a zombie thread. I am a bit confused about where to go with this environment after the discontinuation of the hyperconverged setup. What alternative options are there for us? Or do you think going the Gluster way would still be advisable, even though it seems as it is being discontinued over time? Thanks for any input on this!

querying which LUNs are associated to a specific VM disks
by Sandro Bonazzola 18 Mar '22

18 Mar '22

I got a question on oVirt Itala Telegram group about how to get which LUNs are used by the disks attached to a specific VMs. This information doesn't seem to be exposed in API or within the engine DB. Has anybody ever tried something like this?
