snapshot fail details

[iyadk]

Hello,

I tried to make a snapshot of my Windows Server 2012 VM and got an error message:

Formatting '/var/lib/vz/images/vm-108-state-after-network-config.raw', fmt=raw size=17704157184
snapshot create failed: starting cleanup
TASK ERROR: VM 108 qmp command 'blockdev-snapshot-internal-sync' failed - got timeout

Where can I find the log files after a failed snapshot?

I tried again a couple hours later and it did work. My qm config did not change and I had enough space in my node.

I just want more details on what happened during this situation.

Thanks!

Hi,

Where can I find the log files after a failed snapshot?

See journalctl -f during the snapshot.

Please post the output of pveversion -v and the VM config qm config 108 as well.
