Hi all i have been having major issues with nfs and smb shares attached to my proxmox install. I can no longer take snapshots of any of my vms due to this.

I have tried both pve-kernel-5.15.64-1-pve: 5.15.64-1 and the the 104 kernel. Same issue persists. I am running another server with truenas core and have never had nfs smb permission issues. My windows desktop can see both shares just fine and write to them. I even turned off acl's on my truenas thinking it was a permissions issue. It can mount the share at first and even see storage available on the box but the second I try to backup to the share it says unreachable and com failure and then I cannot see the storage amount unless I reboot node.

This is the type of errors i get on my proxmox node while trying to backup.

As you can see i have storage available on the smb share. But it offlines during the backup call.

Here is my truenas settings for the share.

As you can tell i allowed all and still cannot write. I think its due to the proxmox update. It was running fine every week for backups for multiple weeks. It even ran on the new proxmox update but for some reason halted.
