Support resizing btrfs filesystems.
The existing code has two issues with btrfs: 1) The command to resize a btrfs filesystem uses a path to the mount point, not the underlying device: $ btrfs filesystem resize max /dev/vda1 ERROR: unable to resize '/dev/vda1' - Inappropriate ioctl for device Resize '/dev/vda1' of 'max' $ btrfs filesystem resize max / Resize '/' of 'max' 2) The code that is given a path and finds the ID of the device where the path is mounted doesn't work for btrfs: Use /proc/$$/mountinfo to find the device where path is mounted. This is done because with a btrfs filesystem using os.stat(path) does not return the ID of the device. Here, / has a device of 18 (decimal). $ stat / File: '/' Size: 234 Blocks: 0 IO Block: 4096 directory Device: 12h/18d Inode: 256 Links: 1 Access: (0755/drwxr-xr-x) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2013-01-13 07:31:04.358011255 +0000 Modify: 2013-01-13 18:48:25.930011255 +0000 Change: 2013-01-13 18:48:25.930011255 +0000 Birth: - Find where / is mounted: $ mount | grep ' / ' /dev/vda1 on / type btrfs (rw,subvol=@,compress=lzo) And the device ID for /dev/vda1 is not 18: $ ls -l /dev/vda1 brw-rw---- 1 root disk 253, 1 Jan 13 08:29 /dev/vda1 So use /proc/$$/mountinfo to find the device underlying the input path.
