SOLVED: NAS storage, limited space available

[herbus]

Hi,

I've searched the complete afternoon but can't find the right answer :-(
In PVE I've added my Synology NAS (via SMB and NFS) and it's showing the right disk capacity and used space. Capacity 9,83Tb, free space approx 2,46Tb.

I've used the NAS to store the PVE backups (not PBS) and that worked okay.

Today I've installed the latest version of PBS (in a container and vm, just to find the differences).
If I add the Synology using 'add Datastore'. The datastore is added but the disk space isn't right. Capacity 9,91Gb, free space approx 8,24Gb.


PBS in a container or vm behaves the same, there's also no difference in using the storage via SMB or NFS.
I've looked almost evry Youtube tutorial but missing the clue (or knowledge) to solve it.
Can anyone help me?

Thank you in advance,

Jos

Just a thought, but on Synology, did you set a quota for the user / user-group that you use to connect to the nas from your PBS, or for the share itself?

And if you connect (via smb) to the share that you have set for the backup from your (windows) PC, what size used/max does it show there?

If we compare it between 3 different systems (PC, PVE, PBS) to the same share with the same protocol, we can see who the odd one out is, and if we should focus on why PBS has it "wrong" or why PVE sees something different (most likely caused by the Synology in that regard)

I don't have a quota set on the Synology. Strange is also that in Proxmox the Synology shares have enough space. It seems to mess up when the shares are being used in PBS.

And you compared this with a third system already that it is PBS who's in the "wrong"?

 

[herbus]

The share in PBS is wrong. All the other devices like PVE, windows and Mac can use the share with enough free space.

Your backup storage (mnt/pve/synology-backup) is not mounted to the NAS, but to the local file system of the container (10GB ?).

What does your fstab mount entry of the synology look like?
What is the result of the command df -h?

Hmmmm, that sounds like an issue.
I don't edited fstab. Do I need to do that manualy in /etc/fstab/?

df-h:

Solved!
I've installed PBS is a vm using this tutorial: https://www.youtube.com/watch?v=0V2UhPnLZKY
Great explanation.
