You do not have to. I just gave a hint regarding "is_mountpoint" and that the classic way via fstab is still a valid approach.
I have no idea what works best for you ;-)
Good luck!

Well, it is worth to mention that I have never had this problem. I am really not sure why..., yes I do use network storages.
One way is what what you already tried to achieve and where I pointed out that is seams to not work under all circumstances: mount whatever you want, be it NFS, CIFS or an USB drive. Tell PVE that you have a directory-storage at the respective location. Then tell PVE "...is_mountpoint".
Another approach may be: check manually if the storage is available. If it is not available tell PVE that is is disabled. This can be done by something like
pvesh set /storage/$DATASTORE_ID --disable 1. This check can run every few minutes via a crontab.Some weeks ago there was a script posted here in the forum to disable a storage if that server is not online. Search... here: https://forum.proxmox.com/threads/a...nding-on-host-availability.146105/post-659463

By using the directory "method" i need to mount manually in fstab right?Well, it is worth to mention that I have never had this problem. I am really not sure why..., yes I do use network storages.

Regarding the second method i'm not really a fan of scripts that eventualy get lost in migrations/reinstalls
Correct. A directory with free space must be available to be presented to PVE ;-)
Also correct. This is a "last resort"-approach.
As @alexskysilk said: usually it should "just work" with the configuration options in the official WebGui under Datacenter --> Storage.
If the share is defined in the web GUI (or CLI) using a specific storage type (e.g.
CIFS or NFS), Proxmox VE looks after it. It has more information and control over the share.If you use
/etc/fstab and the Directory type storage, you need to manage whether it is online or not. Proxmox VE only knows it is a directory and does not have any visibility into more than that.I indeed had an CIFS share via the GUI.
Apprently proxmox wasn't looking when my NAS (truenas scale on a VM inside proxmox) went down and filled "local" with 40gb of frigate recordings!
So why are you telling me that proxmox looks after it? that's the bit that i'm missing
Let me see if I understand correctly:
- You were running TrueNAS Scale as a VM in PVE.
- The TrueNAS Scale VM had a CIFS share called
frigate. - You mounted the
frigateCIFS share in PVE.
frigate CIFS share?You understood correctly. Frigate Is an NVR that i have in a container.
When i was fiddling with truenas It went down several hours and frigate kept writing in the mountpoint that was actually offline and so i had 40gb of recordings in the local partition instead of the CIFS share

sure thing
Quick edit: the 40gb files were in /mnt/pve/frigate after i unmounted the share

I have taken a deeper look at the configs you posted.
Your
Your LXC has the following config line:
If your LXC had mounted the share using the storage defined in Proxmox, I would have expected to see something like:
Looking at the storage config, you have not configured the CIFS share to allow container storage. You have:
If it allowed container storage, you would see:
It appears you have manually mounted the share as an arbitrary directory. When mounted that way, PVE will not know it is a share -- in the LXC context.
What you would want to do to prevent writing to that directory when the share is offline is to allow containers in the storage and provision the mount point from the PVE storage instead of using the path.
Your
/etc/pve/storage.cfg has the following:

Thank you for taking time to explain to a noob, i learned that here and i tought it was the "go to" easy mount , clearly i have lot to learn!
