Next attempts simply gave "Invalid argument". Todate BTRFS is not capable to remove (via btrfs device delete <path>) a missing disk. The user has to unmount the filesystem and remount-it in "degraded" mode. I.e.: # umount /mnt/btrfs # mount -o degraded /dev/sdX /mnt/btrfs Now I am noticing that the filesystem is the root filesystem. This is a bit more difficult to handle. I think that you have to pass the right parameter to the boot loader to do that. For example on debian, you must pass the following option to grub (typically to the line of the kernel) rootflags=degraded I don't know i is valid to do something like: # mount -o remount,degraded / BR G.Baroncelli -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
