Hi again Konstantinos.

Can you please attach the full VDSM & Engine logs so we can understand the reason for your problem?

Thanks.

Subject: [ovirt-users] VM has been paused due to unknown storage error

Hello oVirt users,

I am facing a serious problem regarding my GlusterFS storage and virtual 
machines that have *bootable* disks on this storage.

All my VMs that have GlusterFS disks are occasionally (1-2 times/hour) 
becoming paused with the following Error: VM vm02.mytld has been paused 
due to unknown storage error.

Engine Log
INFO  [org.ovirt.engine.core.vdsbroker.VmAnalyzer]

'247bb0f3-1a77-44e4-a404-3271eaee94be'(vm02.mytld) moved from 'Up' --> 
'Paused'

unknown storage error

My iSCSI VM's, some of which may have mounted (not bootable) disks from 
the same GlusterFS storage, do NOT suffer from this issue AFAIK.

My installation (oVirt 3.6/CentOS 7) is pretty much a typical one, with 
a GlusterFS enabled cluster with 4 hosts, 2-3 networks, and 6-7 VMs..

Thanks,

K.
