NFS mounts are not working after migrating a CT

[sunnyside]

After upgrading kernel, it seems the NFS mounts are not working after live-migrating a CT.
The bug is very similar as this one (which is marked as solved in 042stab082_5): https://bugzilla.openvz.org/show_bug.cgi?id=2766 .

Migration seems ok but inside the VE, the NFS mount are not working.

The problem only occurs with pve-kernel-2.6.32-26.
The only solution I found was to downgrade to pve-kernel-2.6.32-23.

Thanks for you help

My mistake sorry.

Downgrading the kernel did not solve the problem.
And it is working fine on another cluster with same kernel version.
So it's not an upgrade problem, neither a kernel problem.

I have a strange message on the when starting (not migrating) the container:
Dec 6 18:01:18 hn-1-1-2 kernel: VE1001: no allowed mount options found for device 0:25

Anyone knows where it comes from ?

Hello Sunnyside,

I'm addressing a similar issue. Have you looked at http://openvz.org/NFS? That may prove useful.
