Could you clarify what is broken?
I understood that it was simplistic (ie if you have a raid0 built over a
raid5
or something exotic then it may have problems) but essentially worked.
Could it be :
* broken for complex raid on raid
* broken for root devices
* fine for 'simple', non-root devices
It works when everything works. If something does not work (your disk
died, you moved disks, or esp. you added another disk from another
machine wich was also a part of (another) raid array), every bad
thing can happen, from just inability to assemble the array at all,
to using the wrong disks/partitions, and to assembling the wrong
array (the one from another machine). If it's your root device
you're trying to assemble, recovery involves booting from a rescue
CD and cleaning stuff up, which can be problematic at times.
