It will have this fixed. do you have a prerelease, i'd like to test the stacking stuff.try: http://www.cse.unsw.edu.au/~neilb/source/mdadm/mdadm-test.tgz It doesn't have an updated version number of anything, but it does try to get --stop --scan right for stacked devices, and it does have
thanks a lot, now stopping stacked devices work.
(I haven't done anything about improving the lot of --assemble for stacked devices)
i did some investigation and found the issue that caused mdadm failing
for me with stacked device.
I am an udev user and i use the --auto flag to assemble to create the
device files.
mdadm does create a device list at the beginning and while reloading the
/proc/partitions file does not add new md devices to the device list, so
i plugged add_dev into open_mddev() and now everything seems to work
perfectly.
patch is attached.
also please add the manpage for mdassemble (also attached)

Luca
