Message-ID: <jsafma$896$1@dough.gmane.org> (raw)
Hello!
Long time ago I created btrfs on /dev/sda
After some changes btrfs moved to /dev/sda1 (well, to md, and sda1 is
part of md).
As result, <btrfs fi show> show me 2 filesystems: new one and old one.
Probably I need to do some cleaning. Can someone tell me what to do.
fdisk -u -c -l /dev/sda
Disk /dev/sda: 2000.4 GB, 2000398934016 bytes
81 heads, 63 sectors/track, 765633 cylinders, total 3907029168 sectors

Last one is wrong.
