looking for non existent devices

Hallo, linux-btrfs,

some commands still look for non existent devices.

I don't use "udev".
When I run

btrfs filesystem show

only the existent devices are shown - fine.

When I run

btrfs filesystem label

or

btrfs scrub status /dev/sdxn

then I get a lot of error messages with (p.e.)

failed to read /dev/hda6: No such device or address failed to read /dev/sdm7: No such device or address failed to read /dev/sr3: No such device or address

Quoted 8 lines

When I run

btrfs filesystem label

or

btrfs scrub status /dev/sdxn

Quoted 5 lines

then I get a lot of error messages with (p.e.)

failed to read /dev/hda6: No such device or address failed to read /dev/sdm7: No such device or address failed to read /dev/sr3: No such device or address

I think this has been fixed in recent btrfs-progs, commit 32eff711.

It is fixed in some (or many) places, it is not fixed everywhere. I had used kernel 3.2.9

32eff711 is supposed to fix it in more places, filesystem label and scrub status included. This is purely a userspace issue, commit and repo I pointed you to are for btrfs-progs, not the kernel. You are probably on branch master, it doesn't have that commit yet, only dangerdonteveruse branch does.
