as I don't see that I can fix this, I intend to re-create the
file-system. For that, I need to remove one of the two discs from the
raid/filesystem, then create a new fs on this and move the data to it (I
have no spare)
Could you please advise me, wheather this will be successful?
first some Information on the filesystem:
----------------
./btrfs filesystem show /dev/sdb1
Label: none uuid: 989306aa-d291-4752-8477-0baf94f8c42f
Total devices 2 FS bytes used 3.47TiB
devid 1 size 2.73TiB used 1.74TiB path /dev/sdb1
devid 2 size 2.73TiB used 1.74TiB path /dev/sdc1
/btrfs subvolume list /mnt/BTRFS/Video
ID 256 gen 226429 top level 5 path Video
ID 1495 gen 226141 top level 5 path rsnapshot
ID 4444 gen 226429 top level 256 path Snapshot
ID 5845 gen 226375 top level 5 path backups
btrfs fi df /mnt/BTRFS/Video/
Data, RAID0: total=3.48TB, used=3.47TB
System, RAID1: total=32.00MB, used=260.00KB
Metadata, RAID1: total=4.49GB, used=3.85GB
--------------------
What I did already yesterday was:
btrfs device delete /dev/sdc1 /mnt/BTRFS/rsnapshot/
btrfs device delete /dev/sdc1 /mnt/BTRFS/backups/
btrfs device delete /dev/sdc1 /mnt/BTRFS/Video/
btrfs filesystem balance start /mnt/BTRFS/Video/
next, I'm doing the balance for the subvolume /mnt/BTRFS/backups
In parallel, I try to delete /mnt/BTRFS/rsnapshot, but it fails:
btrfs subvolume delete /mnt/BTRFS/rsnapshot/
Delete subvolume '/mnt/BTRFS/rsnapshot'
ERROR: cannot delete '/mnt/BTRFS/rsnapshot' - Inappropriate ioctl
for device
Why's that?
But even more: How do I free sdc1 now?!
Greetings,
Hendrik
