vzdump times out no clue why

[hmontoliu]

Hello

since a few weeks ago the vzdump process times out.

Here is the log:

vzdump 100 --quiet 1 --mailto root@localhost --mode snapshot --compress lzo --storage backups-VMs --node node01host

100: jun 07 02:00:04 INFO: Starting Backup of VM 100 (qemu)

The destination is a mounted ext3 partition:

/dev/mapper/backup-VMs on /var/local/backups-VMs type ext3 (rw)

There is plenty of free space to allocate the whole backup:

/dev/mapper/backup-VMs
                      459G  199M  435G   1% /var/local/backups-VMs

Monitor shows the following status:

qm> info backup
Backup status: error - backup cancelled
Backup file: /dev/fdname/backup

Total size: 268435456000

I have no clue of what is happening so any help would be appreciated.

Thanks in advance

Any clues to where to start looking at?

You should first update your installation, because you run a quite old version.

Sure I should, but it is a production server and I can't schedule a upgrade for a while.

I've found this thread:

I'll tell you if increasing the timeout value allows vzdump to continue and start the backup or not:
