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.
