Hi Mark,

process.

But please send the content of the /etc/fstab and /var/log/messages.

Hi Mark,

Can you please send the engine log and the VDSM log.

This will help us to make a deeper investigation on the scenario that you
described.

Thanks.

[ovirt-users] Storage Migration issues

[Mark Steele]

Hello,

We have begun migrating VM boot disks from one Storage domain to another.
Both the storage domains are NFS and both are V3. The Ovirt instance is oVirt
Engine Version: 3.5.0.1-1.el6

I am shutting down the VM's prior to migration (not a live migration). When
the disks complete their move, I start the VM back up on the original host.
The hosts are all running either Ubuntu 14.04 LTS or 16.04 LTS

I have experienced the following two issues:

- when the VM's come back up, they are not mounting an external NFS mount
that is defined in /etc/fstab. The mount can be reinstated manually and
survives subsequent reboots - but every VM that has an external NFS mount
has this issue after migration

- VM's that have a docker instance running no longer respond to web
requests on the web server ports that the docker instance is running.

Any thoughts on why this would happen would be greatly appreciated.

Best regards,

***
