[Users] VPS on NFS?

[Thomas Gautier]

I have the exact same problem using CentOS5 + GFS on a clustered iSCSI  
SAN storage. I have 4 server nodes running CentOS5 + vz.

The VE_ROOT and VE_PRIVATE folders are on the shared storage. Whenever  
I boot a container stored on the SAN I don't have any networking at  
all. But if i copy the files from the SAN to the local disk on a node  
and launch the container, it works.

Any idea on the problem would really be appreciated,
Thomas Gautier.
