btrfs-progs: Introduce device delete by devid
This patch introduces new option <devid> for the command btrfs device delete <device_path|devid>[..] <mnt> In a user reported issue on a 3-disk-RAID1, one disk failed with its SB unreadable. Now with this patch user will have a choice to delete the device using devid. The other method we could do, is to match the input device_path to the available device_paths with in the kernel. But that won't work in all the cases, like what if user provided mapper path when the path within the kernel is a non-mapper path. This patch depends on the below kernel patch for the new feature to work, however it will fail-back to the old interface for the kernel without the patch Btrfs: Introduce device delete by devid Signed-off-by: Anand Jain <> Signed-off-by: David Sterba <>
