Hi,

install of Proxmox 8.2.2 for testing before upgrading cluster.

SMB share on Synology NAS. Synology is in other office using NAT traversal with TCP/445 forwarding to it from main office. Working fine with 6.3-3 and 7.3-3

On pve10 running 8.2.2
smbclient -U pvecluster //[MY IP ADDRESS]/NetBackup -c 'ls' - works as expected

cat /etc/pve/storage.cfg
..


cifs: HopeStSynology
path /mnt/pve/HopeStSynology
server [MY IP ADDRESS]
share NetBackup
content images,backup
nodes vm3,pve10
prune-backups keep-all=1
username pvecluster

vm3 is running 7.3-3 and works as expected. pve10 running 8.2.2 and doesn't

Summary for the share is Enabled = yes and Active = no.

Clicking on the share then Backups, error message is unable to activate storage 'HopeStSynology' - directory '/mnt/pve/HopeStSynology' does not exist or is unreachable (500)

Browsing to /mnt/pveHopeStSynology/dump I can list all the backups in there. I can also create and erase files.

I'm stumped. If anyone has ideas I'd appreciate it.

Perhaps: "/mnt/pve/HopeStSynology" <> "/mnt/pveHopeStSynology/dump" ;-)

I can write to the folder?

Changed SMB server to allow asynchronous reads and multichannel. PVE10 is now connecting, even after reboots. I'm not sure if the SMB settings change are the fix or simply because I've restarted the SMB server.
