Loosing connection to NAS share

[FrankAusNRW]

Hi there,
I'm operating my two Proxmox nodes now since a few weeks.
Currettly the hazzle is, that my nodes sometimes looses the storage added to my QNAP NAS, that is mainly used for backups.
Important to mention, that the NAS ist part of an AD domain, just migrated to UCS5.

Initially the share was mapped as SMB/CIFS and worked with domain/user/password.
BUT: Everytime, when I had to do a reboot of the NAS or on one of the PVE nodes, the connection does not work anymore. Just shows in the list of shares, but with a small questionmark in the bottom right corner.
Ok, next attemp was to use NFS instead of SMB/CIFS, and it initially also worked - just until I had to reboot one of the pve cluster.
I've also tried to map the share on the CLI with "pvesm add cifs ...", but this also does not work: "storage ... is not available".

Currently I can't get the share mapped at all, neither as SMB/CIFS nor as NFS.

Looking at the share from a Windows Client the share is available and working.

Any idea what's wrong here? ThanX!

Frank

hard to say what is going on with the information provided. What I can say is that CIFS can work very stable with Proxmox. I have a CIFS storage running that survives reboots of either Node oder CIFS-Server. It's provided by SAMBA on Debian.

To debug this, I would set logging to verbose on the CIFS-machine and check what happens when the Proxmox node tries to connect. This should give you hints on what is really going on.

It's weired ... Setting the Loglevel on the QNAP seem to be a bid tricky.
I've solved it now by using another name for the storage at the proxmox device and this works.
So it seems as if proxmox is having a problem with re-using an already used descriptive name for the storage after this has been disconnected.
