Hi,
I found out why this happens.
1. I have 2 Proxmox Servers, both have an NFS mount (daily_backups).
2. The NFS Server Machine shuts down the NFS share for 5 seconds every day at 3:00 PM (NFS Server issue with deleted files)
3. Machine 1 keeps the NFS mount alive and active
4. Machine 2 drops the NFS link. It's still in /etc/mtab, but no longer in df.
Both servers are running the same Proxmox version. The only differences are the network cards and CPU type (AMD vs Intel).

I'm eventually hoping to put my Image storage on DRBD backed NFS. Which means on a DRBD failover, the NFS link will be gone for 5-10 seconds. Am I looking at trouble with this scenario? Why is one machine losing the NFS mount, and not the other?
