Hi All,
I have reproduced the backups failure. The VM that failed is named
Win-FileServer and is a Windows 2016 server 64bit with 300GB of disk.
During the cloning step the VM went unresponsive and I had to stop/start
it.
I am attaching the logs.I have another VM with same OS (named DC-Server
within the logs) but with smaller disk (60GB) which does not give any error
when it is cloned.
I see a line:
EVENT_ID: VDS_BROKER_COMMAND_FAILURE(10,802), Correlation ID: null, Call
Stack: null, Custom ID: null, Custom Event ID: -1, Message: VDSM
v2.sitedomain command SnapshotVDS failed: Message timeout which can be
caused by communication issues
I suggest adding relevant vdsm.log as well.
Y.
I appreciate any advise why I am facing such issue with the backups.
thanx,
Alex

I have Windows VMs, both client and server.
if you provide the engine.log file we might have a look at it.

Hi,
I have observed this logged at host when the issue occurs:
VDSM command GetStoragePoolInfoVDS failed: Connection reset by peer
or
VDSM host.domain command GetStatsVDS failed: Connection reset by peer
At engine logs have not been able to correlate.
Are you hosting Windows 2016 server and Windows 10 VMs?
The weird is that I have same setup on other clusters with no issues.
Thanx,
Alex

Hi,
We have a cluster of 17 nodes, backed by GlusterFS storage, and using this
same script for backup.
we have no issues with it so far.
have you checked engine log file ?

Hi all,
I have a cluster with 3 nodes, using ovirt 4.1 in a self hosted setup on
top glusterfs.
On some VMs (especially one Windows server 2016 64bit with 500 GB of
disk). Guest agents are installed at VMs. i almost always observe that
during the backup of the VM the VM is rendered unresponsive (dashboard
shows a question mark at the VM status and VM does not respond to ping or
to anything).
For scheduled backups I use:
https://github.com/wefixit-AT/oVirtBackup
The script does the following:
1. snapshot VM (this is done ok without any failure)
2. Clone snapshot (this steps renders the VM unresponsive)
3. Export Clone
4. Delete clone
5. Delete snapshot
Do you have any similar experience? Any suggestions to address this?
I have never seen such issue with hosted Linux VMs.
The cluster has enough storage to accommodate the clone.
Thanx,
Alex
