Hi, I was creating a documentation about a local raid setup and typed "mdadm --manage --run /dev/md1" This was on a running array and the command returned: mdadm: failed to run array "/dev/md1": Device or ressource busy. I thought, alright, this makes sense /dev/md1 is already started and mounted as /, so running it again does not work. Unfortunately I was not able to do anything useful after that, since all shell commands, like ls failed. Investigating this a bit on a testmachine I found out that the raid array was shut-down and marked as clean due to this run command. So, what happened was that the / fs was still mounted but the raid-device was not running anymore and thus I could not do anything useful with the system. I've tested this on two different machines, running kernel 2.4.23 with the grsecurity patch. Is this a bug or expected? In my opinion the run command should not stop an already running (and mounted) array.
