Dashboard showing wrong amount of free disk space

[Alex_P]

Hello to everyone. On my unraid server, I have a Btrfs RAID5 pool that apparently shows an inconsistent number of free space. I assume this is because there are Btrfs snapshots saved on this drive. However, I would consider this as a bug.

 

When issue df -H command it shows me:

/dev/sdc1       6.2T  363G  3.8T   9% /mnt/daten

 

Also on the pool page:

 

Not so on the dashboard:

 

Is anyone else experiencing this behavior?

Not recommended, be sure you keep good backups.

See the RAID section of this article, and many others.

The dashboard is basically showing the wrong amount of used space, free will be correct, but like mentioned btrfs raid5/6 has known issues, recommend updating to v6.12 and using zfs raidz instead.

Thank you for pointing me in the right direction👍 Didn't know about this downside but I'm aware that zfs is coming. That's the plan anyway to migrate.
