vCenter Linux Guest Pre-Freeze Snapshot Timeout

Post by Vasko » Nov 06, 2013 10:29 am

Hi Guys,

I searched google and these very forums. But nothing I found was related to linux quiesce:

I'm using Veeam B&R for backing up a debian linux guest which has several databases on it. In order to create a dump of the database, I'm making use of the pre-freeze/post-thaw scripts. Now the Problem is, that the script takes about 30mins. However the snapshot get's a timeout after 15mins (See vmware.log of said machine).

Is there a way to increase the timout to 30+min? Or am I mistaken and the timeout is not the cause?

vmware.log:

Code: Select all

Thanks in advance,

The snapshot creation timeout happens in vCenter, but have you checked if maybe the snapshot itself is beeing made in the ESXi holding that VM? It's a known problem on vCenter, look here:
http://kb.vmware.com/selfservice/micros ... Id=1004790

A super quick workaround so would be to point Veeam directly to the single ESXi server, and create the snapshot from there.

For extending vCenter default timeouts, look here:

That was exactly what I was looking for. Thank you! I will try it later.

So, I changed the timeout values exactly as described here in both, the vCenter Server and the ESXi Host and restarted them afterwards.

But nothing changed. The Backup fails exactly after 15 Minutes and the vmware.log shows the "Timed out while quiescing the virtual machine." error.

Any suggestions?

Hi Vasko

Do you solved the Problem? I'm having the exact same issue here.
I applied everything discribed in this VMware KB: kb.vmware.com/kb/1017253

Let me know..

Dominik, I would consult VMware on why timeout values do not take any effect and how to configure them properly.
