I am unable to backup an OpenVZ machine on NFS share. Local backup of the same VM is OK. Here is a part of the log:

Any help will be appreciated.
 
Is there enough free space on the NFS share? Does 'root' have write permissions on the NFS share?

Yes, there is enough space on the NFS share. As for permissions - I think there should be no problems, because I backup successfully on the same NFS share KVM machines. Is there a difference in the connection to the nfs share when OpenVZ VM is backuped? Just for info, I am using Windows 2003 R2 NFS server.

we do an rsync to the NFS share, so the NFS server need to be posix compatible.

Please can you test with another NFS server?
 
The Windows 2003 R2 NFS server is part of the Subsystem for UNIX-based Applications (SUA) which is posix compatible (that's the whole idea of SUA).

Anyway, when I stop the OpenVZ machine (backup mode: stop), everything is OK. The problem is probably on my side, because I am running the OpenVZ machines on drbd/ocfs2 partiton.

Thank you for your support.
