OpenVZ containers on NFS

[guillem]

Hi,

I'm facing a few issues with a proxmox installation where i'm storing containers in an NFS share. Initially i had the ACL enabled and that was not working well at all, so i disabled it and things seemed to improve. I'm still facing a few issues though. For example:
- adding a user reports a problem with locks on the /etc/groups file
- cannot seem to use setcap inside containers

Any clues? From my investigations, some of those may be related to NFS limitations, but i'm not completely sure. Would i be better off using GlusterFS? Maybe i would not face those issues?

Cheers

Containers in GlusterFS does not work well. E.g live migration fails with a kernel error.

any idea on fixes for the locks and the setcap using NFS?

Locks problem requires exclusive locks to propagate through NFS - I think this is not supported in NFS nlockmgr.
setcap should be possible if you use NFSv4 with acl.
