Hello,
I was playing with btrfs and accidentally formatted the disk directly
(/dev/sdb instead of sdb1). Since then I rewrote the GPT partition
table, recreated the partition and ran btrfs device scan. Still, btrfs
filesystem show prints:
root@horus /mnt # btrfs fi sh --all-devices
failed to read /dev/sr0: No medium found
Label: 'test' uuid: ffab72f2-eff1-4ac8-a694-d56dd84fda24
Total devices 1 FS bytes used 28.00KB
devid 1 size 2.73TB used 2.04GB path /dev/sdb
Label: 'home' uuid: c465d715-098a-4d0d-bebc-6aa51f4cb349
Total devices 1 FS bytes used 28.00KB
devid 1 size 2.73TB used 2.04GB path /dev/sdb1
Btrfs Btrfs v0.19
Label home is the actual partition in use but how can I get rid of
label test which was the accidental formatting? Is this just some
cached value or still persistent on the disk?
Thanks,
Florian
