We were running Proxmox 1.9 and few weeks ago upgraded in to Version 2.2 latest release. Sometimes our NFS server hung because of the storage lockdown (storage pingable bu no keyboard action at all) but with the help of the NFS mount options on storage.cfg, when we reboot the storage everything goes fine from where it hung.
Our storage.cfg has that line in it for the NFS share ;
options vers=3,rw,rsize=4096,wsize=4096,hard,intr
We're running KVM's, they're on the NFS share as before and today storage lock down but when it comes back with a reboot KVM's shutdown by them selves. /var/log/messages shows the incident started by this logs ;

Our storage.cfg has that line in it for the NFS share ;
options vers=3,rw,rsize=4096,wsize=4096,hard,intr
We're running KVM's, they're on the NFS share as before and today storage lock down but when it comes back with a reboot KVM's shutdown by them selves. /var/log/messages shows the incident started by this logs ;
