[ovirt-users] Re: [Gluster-users] VMs paused - unknown storage error - Stale file handle - distribute 2 - replica 3 volume with sharding
Hi, is there a way to recover file from "Stale file handle" errors? Here some of the tests we have done: - compared the extended attributes of all of the three replicas of the involved shard. Found identical attributes. - compared SHA512 message digest of all of the three replicas of the involved shard. Found identical digests. - tried to delete the shard from a replica set, one at a time, along with its hard link. Shard is always rebuilt correctly but error from client persists.

[ovirt-users] GetGlusterLocalLogicalVolumeListVDSCommand execution failed: null
Hi,
I'm updating ovirt to 4.2.6.4-1.el7
Engine is updated
Compute nodes are updated
Storage nodes are not yet updated because ovirt 4.2.6.4-1.el7 depends on
gluster 3.12 while now I have gluster 3.10.
Compatibility Versions:
Compute datacenter 4.2
Storage 4.1 (because I don't have yet updated the storage cluster)
so Data Centers is still 4.1
I was about to upgrade the storage nodes when I noticed that
/var/log/ovirt-engine/engine.log is flooded with errors like:
2018-10-25 19:36:17,164+02 ERROR
[org.ovirt.engine.core.vdsbroker.gluster.GetGlusterLocalLogicalVolumeListVDSCommand]
(DefaultQuartzScheduler2) [55e89794] Command

VdsIdVDSCommandParametersBase:{hostId='84a33357-1d04-44db-b0e3-4638ebc39d6c'})'
execution failed: null
6 errors (one for each storage server) every 6 seconds.
How could I fix them?
Can I continue to upgrade the storage nodes?
Best regards,

Re: [ovirt-users] ovirt 4.1 - skylake - no avx512 support in virtual machines
Skylake-Client does _not_ have AVX512 (I tried now on a Kaby Lake Core i7 laptop). Only Skylake-Server has it and it will be in RHEL 7.5. Thanks, Paolo Ok, we'll stay with pass-through until RHEL 7.5.

[ovirt-users] ovirt 4.1 - skylake - no avx512 support in virtual machines
