Does anyone know why checkpoints fail when an NFS volume is mounted? I was hoping to be able to do a live migration of VE but several services' config files and binaries reside on a global NFS mount. Below is a sample of the migration output (with minor modifications to protect the innocent Wink

) Is there any hope for a resolution to this in the future?

Thanks,
Chris

At the moment NFS is unsupported for migration. You can fill an enhancement bug report at bugzilla.openvz.org, and, probably sometime we'll fix the bug.

Thank you,
Vasily

vzdump also fails with nfs mounted. Is this bug the same as the problem that I'm having??

EXAMPLE 1:

[root@vz01 ~]# vzdump --suspend 101
INFO: starting backup for VPS 101 (/vz/private/101)
INFO: starting first sync /vz/private/101 to /vz/dump/tmp23416

EXAMPLE 2:

root@vz01 ~]# vzdump --suspend 101

Trying to run vzdump but fails.
