Re: Ovirt Cluster completely unstable
by Leo David
Just thinking....
Maybe different options where configured to the volumes during update, that
could make them unstable ?
ie: sharding or something else

oVirt upgrade to specific version
by Leo David
Hi,
I have a running 4.2.7 hci cluster which I would upgrade to 4.2.8.
If I do this in the standard manner (yum update in engine vm and then the
nodes from engine UI) I assume it will go to 4.3, which I would rather
avoid for now.
Is there a way for getting it updated strictelly to 4.2.8 ?
Thanks,
Leo

Ovirt Cluster completely unstable
by dscott＠umbctraining.com
I'm abandoning my production ovirt cluster due to instability. I have a 7 host cluster running about 300 vms and have been for over a year. It has become unstable over the past three days. I have random hosts both, compute and storage disconnecting. AND many vms disconnecting and becoming unusable.
7 host are 4 compute hosts running Ovirt 4.2.8 and three glusterfs hosts running 3.12.5. I submitted a bugzilla bug and they immediately assigned it to the storage people but have not responded with any meaningful information. I have submitted several logs.
I have found some discussion on problems with instability with gluster 3.12.5. I would be willing to upgrade my gluster to a more stable version if that's the culprit. I installed gluster using the ovirt gui and this is the version the ovirt gui installed.
Is there an ovirt health monitor available? Where should I be looking to get a resolution the problems I'm facing.

ovirt-4.3 hyperconverged deployment - no option for "disc count" for JBOD
by feral
Vanilla install of ovirt-node-4.3 (iso). During hyperconverged wizard,
there is no option for disc count for JBOD. This results in error during
deployment.
Disc Count option is available for all other raid levels.

Upgrade from 4.2.7 to 4.3.0 troubles
by mariani.alberto＠libero.it
Hello All,
I'm trying to upgrade a Self Hosted Engine installation from 4.2.7 to 4.3.0.
I was able to update the Engine itself, but when I try the general update for both the Engine VM and the Self Hosted Nodes the update fails because the openvswitch-ovn-* packages want a long series of libraries as dependencies, all with the name librte_*
Unfortunately, I don't think these exist in CentOs 7, so I'm having no luck in finding them.
Am I doing something wrong?
Best Regards,
Alberto M.

Re: Ovirt Cluster completely unstable
by Ryan Bullock
Just to add, after we updated to 4.3 our gluster just went south.
Thankfully gluster is only secondary storage for us, and our primary
storage is an ISCSI SAN. We migrated everything over to the SAN that we
could, but a few VM's got corrupted by gluster (data was gone). Right now
we just have gluster off and set to maintenance because the connectivity
issues were causing our main cluster to continuously migrate VMs.
Looking at the gluster hosts themselves I noticed that heal info would
often report one brick down, even if ovirt didn't. Checking the status of
glusterd would also show health checks failed.
Feb 6 15:36:37 vmc3h1 glusterfs-virtstore[17036]: [2019-02-06
23:36:37.937041] M [MSGID: 113075]
[posix-helpers.c:1957:posix_health_check_thread_proc] 0-VirstStore-posix:
health-check failed, going down
Feb 6 15:36:37 vmc3h1 glusterfs-virtstore[17036]: [2019-02-06
23:36:37.937561] M [MSGID: 113075]
[posix-helpers.c:1975:posix_health_check_thread_proc] 0-VirstStore-posix:
still alive! -> SIGTERM
I think the health-check is failing (maybe erroneously) which is then
killing the brick. When this happens it just causing a continuous cycle of
brick up-down and healing, and in turn connectivity issues.
This is our second time running into issues with gluster, so I think we are
going to sideline it for awhile.
