I have a Synology with High Availability serving NFS storage to Proxmox. 
A couple of months ago, this started happening:

Apr 24 12:32:51 proxmox-1 pvestatd[3298]: unable to activate storage 
'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable
Apr 24 13:08:00 proxmox-1 pvestatd[3298]: unable to activate storage 
'NAS' - directory '/mnt/pve/NAS' does not exist or is unreachable

It affecting backups and VM speeds. Any idea what is causing this? There 
are no errors in the Synology logs, and the storage stays mounted and 

Any ideas what's going on?
