VM disk images are gone

Hey everyone,

I'm really struggling to get my VMs to be stable and could use some help/guidance on what I'm doing wrong. I've done some Googling and looked through the forum posts, but feel like I'm not searching the right thing.

Here's the situation:
  • I have 4 hosts, each with a VM on them, labeled Prox-1 through 4
  • Prox-1 and 4 have an ubuntu server VM on them that is running off of the local disks no problem.
  • Prox-2 and 3 have ubuntu VMs with the VM disk data being stored on my Unraid server. I had NFS shares being exported from Unraid and added in Proxmox via Datacenter > Storage.
  • I had an error where the backup operation was failing which has been resolved.
  • However, now I am getting 'stale file handle' errors when the backup operation runs overnight.
  • Concurrently, I am also getting "read only" file system errors on the Prox-2 & 3 VMs when left overnight. They will boot fine off of the network storage, and then something happens overnight that causes them to lock up and I have to kill the whole VM process and reboot to unstick them.
  • I deleted the VM-Datastore share as NFS and readded it as SMB (in Datacenter > Storage), but now on both nodes under the "VM-Datastore" storage, no VM disk is showing up. Issue persists after setting the same share back as NFS.
  • I tried to just recreate the VMs using the local SSD in the host (with the Proxmox OS files on it) as the disk storage location like on Prox-1 and 4, but it's not showing up as a storage option when creating the VM. Ican't seem to find a walkthrough on how to format the local LVM partition so that it shows up as a VM storage option.

Apologies for the basic question, I'm still new to Proxmox and trying to learn how to do things as I upgrade from Unraid. I would love to have the storage remotely if possible, but ultimately just want this to work reliably and local storage seems to be the more reliable option as the VMs on Prox-1 and 4 have been rock solid.
 
Update: I restarted the hosts and the shares reconnected. I changed my Backups share to connect via SMB and turned the 'Support Hard Links" option to 'no' in Unraid. I ran a backup job and 1 of 4 vms has completed successfully so far (others are in progress).
