Store OpenVZ-Containers on a NFS-Share

[MasterTH]

Hi,

i was wondering that it is possible to mount a nfs share and put some kvm-maschines inside, but not openvz-Containers?

is there any workaround?

Thanks

You sure can. Just add the NFS shares to your Proxmox in the storage settings.

I have both local and nfs shares, but I am bit confused.
If I do a live migration sometimes I get errors such as:
Error: _rst_get_object: wrong object type: 1030 (expected: 1045)
Error: rst_open_file: failed to lookup path '/tmp/.nfs000000000038000400000109': -2
ERROR: online migrate failure - Failed to restore container: Can't umount
/var/lib/vz/root/101: Device or resource busy

I do not understand why, my container was created in the NFS share, why am I getting error messages regarding local disk.
I looked closer and it seems that root is in the local disk and private is in the nfs share.
I do not even want to use the local disk.

I tried removing the settings from storage.cfg, but it always shows in the gui and the issue did not go away.

How do I remove the local disk share completely. I only really need the NFS share.

My setup is at the latest releases.

BTW, it does migrate regardless of the errors and then starts, but I have a copy of the VM in root in .var.lib.vz and the same amount of storage in private in NFS share.

ON another note, today it is behaving differently. After the failure the ct moves back to source node and starts again automatically.
To get it to work I have to remove the ct from the HA, then stop it and then do an offline migration.

Meaning I can not live migrate.

Both are known bugs, thanks for reporting.

Any work around posted somewhere.
Can I remove local disk completely to eliminate the issue.

Thanks for quick reply.

I modified the ROOT line in the ct conf files topoint to the NFS share with the same strcuture and it is working now .
My concern is that if I create a CT on the NFS share which has 10 terabytes, then the system gets filled also does not have that much space.

I guess if I have to to modify the conf file and point to the NFS share after the fact I can live with that and then I can remove the folder from /var/lib/vz/root which is taking uneeded space.

Thanks
