[SOLVED] Incorrect Total Storage Size Display for BTRFS Directory Storage in Proxmox VE 9.0.11 x86_64 GUI

[kolanob]

Hello everyone,

I’m encountering an issue in Proxmox VE 9.0.11 (x86_64) related to storage monitoring in the GUI.

I have a Directory storage configured on a BTRFS filesystem using a 1 TB NVMe disk mounted at /mnt/storage-btrfs-1tb. The actual disk size and usage are correctly reported by Linux commands like:



However, the Proxmox GUI wrongly shows the total size as about 225 GB, not the real size. The usage bar reacts correctly to space used but is based on this incorrect total size, which causes confusion.


I tried restarting Proxmox services, the entire server, clearing browser cache, and removing/re-adding the storage, but the problem persists.

Is this a known bug or limitation? Has anyone found a workaround? Any ideas or fixes would be greatly appreciated.

Thanks in advance!

seems not mounted or wrong directory path.
post storage.cfg content and "mount" output.
plz, no screenshot, copy/paste in CODE forum tags.

Hello,

Thank you very much for the help! The problem was caused by a mismatch in the storage configuration path.

In my /etc/pve/storage.cfg file, the path for the BTRFS directory storage was set to /mnt/local-btrfs-1tb, while the actual disk was mounted at /mnt/storage-btrfs-1tb.

This mismatch caused the Proxmox GUI to show an incorrect total size (~225 GB) instead of the real disk size (~931 GB).

After correcting the path value in the configuration file to match the actual mount point (/mnt/storage-btrfs-1tb) and restarting the Proxmox services, the GUI now correctly displays the full disk size.

Thanks again for pointing me in the right direction!

Hello, kolanob.

What were these commands? You have shown only the output, no the commands.
