Hi, I have a strange problem with a btrfs partition : after an error, btrfs was forced readonly. So I try to umount it, to launch btrfsck, but it doesn't work : root! sofia:~# umount /backup/ root! sofia:~# btrfsck /dev/vg-sofia/backup /dev/vg-sofia/backup is currently mounted. Aborting. root! sofia:~# umount /backup/ umount: /backup/: not mounted root! sofia:~# btrfsck /dev/vg-sofia/backup /dev/vg-sofia/backup is currently mounted. Aborting. root! sofia:~# And I can't remount it : root! sofia:~# mount /backup/ mount: /dev/mapper/vg--sofia-backup already mounted or /backup busy Or access to the content : root! sofia:~# ls /backup/ root! sofia:~# It's on a v3.4.7 kernel, with btrfs-tools version 0.19+20120328-7 (from Debian unstable). What should I do ? Reboot ?
