Hi Lubos,

=46irstly if I understood the documentation right, you have to specify
the mount point rather than the drive itself.
Secondly, I posted about this issue a while ago. It seems that it will
only extend the filesystem on the hard drive that has devid 1. If you
do not have any drives with devid 1 (e.g because you removed it), you
can't resize your drive.

I hope this is something that the btrfs developers will look into
ASAP, because as it is now, resizing the FS on RAID arrays is
impossible.

Regards,
Sebastian J.
