I just tried btrfs for the first time. I notice that the size reported is not correct (unless I misconfigured the btrfs mount). In total the volume is around 3 Gb. How is the used space calculated? At this stage I have nothing on that volume.
the mount is a raid0:
→ btrfs filesystem show /mnt/btrfs_pool
Label: none uuid: baa9db51-b64a-4e6b-b9fe-af860e0ea51d
Total devices 3 FS bytes used 144.00KiB
devid 1 size 1.00GiB used 102.38MiB path /dev/nvme2n1
devid 2 size 1.00GiB used 366.38MiB path /dev/nvme3n1
devid 3 size 1.00GiB used 366.38MiB path /dev/nvme4n1
Looking into this it seems BTRFS does not easily show total available space and dysk is doing that for me. Just not sure how the used space is calculated.
