btrfs mount shows wrong size

[tmaennle]

Hi there,
on a test system which is installed on 2 disks in btrfs raid1 mode, i manually added another btrfs pool consisting from 4 disks in raid10, added it to pve. If i switch to this additional storage, it shows the same size as the storage from installation, see screenshots... bug?

cheers, Tobias.

4 partitions ?! So if you define 4 further btrfs filesystem volumes you should define in datacenter somethink like local-btrfs1 ... until local-btrfs4 as you define the storage by id ... so if you have 4 (additional to the default on os disk) you need 4 names for that (while the one on os disk has no number).
So your name local-btrfsraid10 is not the btrfs10 as it's just 1x 1TB volume of it ... and so the display in pve is right and your fault !!

you sure you read it right?

Looks to me like your Btrfs is mounted at /local-btrfsraid10 in /etc/fstab but your local-btrfsraid10 storage is set at /mnt/local-btrsfsraid10 (which is a directory on local-btrfs). /local-btrfsraid10 is not the same as /mnt/local-btrsfsraid10. Change one of those to match the other.
