Couple of issues with Proxmox3

[keyjey]

Helo, I have 3 servers in a cluster, all fine, but I'm experiencing a couple of issues.

1.- The last server added has 4 KVM VMs, nothing special, there's nothing "working" high, but I see an permanent IO Delay of 23%. Any tip about this ? the disks are really doing NOTHING, VMs are practically sleeping.

2.- Since KVM VMs are in general working well, I'm unable to restore a small OpenVZ partition in one node. This a shared NFS inside a LVM partition. Ptoxmox just have the NFS shared system and the restore process never finish. Restoring this same backup in another node in a "local storage" works like a charm.

I hope you can give me any ideas, thanks !

For problem 1 install iotop and run it to see what is doing the IO.

I see a couple of processes with some activity, one is the nfsd daemon, and the other one (99% IO) is the process [jbd2/dm-1-8].

Is the daemon syncing the VMs ? When I do a online migration is almost instant. Could this be the explanation ?
