Scheduled vzdump snapshot backups failure over a remote (local lan) NFS NAS.
The subject of the notification email is as follow:

Code: 
vzdump backup status (mynode) : backup failed: can't aquire lock '/var/run/vzdump.lock' - got timeout

Indeed I can see the lock in place by running:

Code: 
mynode:~# lsof | grep vzdump.lock
task      833423              root    4wW     REG               0,18           0         1248173 /run/vzdump.lock

After killing the process (833423 in this case) the next scheduled backup runs fine.
The one after, dies and we go back to square one.

Summary of the events:

1. scheduled backup failure,
3. lock removed,
4. scheduled backup OK
5. GOTO 1.
​

Ideas? :confused: Where do I find more hints, logs etc?

My software versions are:

Rebooted all the nodes.

Scheduled backups over NFS started working fine again.

I suspect it was a previous debian update/upgrade of kernel components that required a proper reboot.

Issue resolved.
 
I am having the same issue.

Scheduled backups are failing for a Windows 7 KVM.

It starts but fails and I get the email notification:-

"vzdump backup status (proxmox1) : backup failed: can't aquire lock '/var/run/vzdump.lock' - got timeout"

I have tried both snapshot and stop methods of backup, but get the same error.

Command
vzdump 102 --mailnotification always --quiet 1 --mode stop --mailto backupnotify@domain.com --node proxmox1 --compress lzo --storage nfs1

Can anyone help?

In the meantime, how do I perform a manual backup by GUI or command line?

Thanks in advance.
