I try to unmount /dev/sda11, cuase I want to label it but I get this

  umount /dev/sda11
umount: /var/run/media/root/suse1-copy: target is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))

so I try fuser and this is what I get

 fuser -mv /dev/sda11
                     USER        PID ACCESS COMMAND
/dev/sda11:          root     kernel swap  /dev/sda5

Sp what processes should I kill, only those marked with m ? e.g : plugin container PID 4481 ??

No, you shouldn’t kill any of those.

Use “fuser /var/run/media/root/suse1-copy” or “lsof /var/run/media/root/suse1-copy” to find out which process is still using it.
You want to unmount the filesystem/mount point (and that is in use), not the device file…

PS: As you apparently monted it with the file manager/desktop environment, why don’t you use that to unmount it?
Or try “udisksctl unmount -b /dev/sda11” (as root obviously, since you also mounted it as root).

no I’ve fstab entry for that so it mounted automatically

4

OK, /var/run/media confused me, as that is used by udisks2 (and the desktop environments therefore).

Anyway, see my previous reply regarding lsof/fuser.

5

ok so I unmounted it but when I want to label it this is what I get

 e2label /dev/sda11 suse1-root_copy
e2label: Bad magic number in super-block while trying to open /dev/sda11
Couldn't find valid filesystem superblock.

I created this partition as blank an then untar here the backup of my tumbleweed but without the /.snaphots and /sys /proc /dev/pts. and in rescue mode it was running ok (I could’t run it normally cause in grub I recognized it by label and it wasn’t labeled and btrfs only outputing this # fsck -t btrfs /dev/sda11
fsck from util-linux 2.23.2

Well, you CANNOT use e2label for btrfs partitions.
e2label is for ext2 (and 3/4) filesystems, obviously.

Use:

btrfs filesystem label <dev> [newlabel]

Btw, grub doesn’t care whether you mount your filesystem by label or what else in fstab.
And I have no idea how fsck is related here now.
