The documentation look completely clean. It could be good to add details if the drive is failed for hw issue, if the drive need to be replaced before launching this procedure. It's the way I would understand it, reading it, but could be good to detail that it's safe to replace the drive after seeing that the reason of the CrashLoopBackOff is the drive.
