create /dev/md0 with /dev/sda (sata) level=1 raid-devices=1 format /dev/md0 with bcache format /dev/sdb (ssd) with brache create bcache0 with /dev/md0 and /dev/sdb why this is not possible? 2013/7/3 matthew patton <[email protected]>: > short answer you can't. you can unbind the SSD from bcache and otherwise > remove the bcache config but you can't turn a live disk into a MD raid member > without destroying all data on it.
