Re: RAID5 not being reassembled correctly after device swap

[Michael Frotscher <infomails@tronserver.dyndns.org>]

Hello all,

I guess you can say that I'm at my wit's end. I really don't get it. An RAID 
array is suppose to recognize its members purely by its uuid, isn't it? So 
technically, I can remove a drive from one bus, reconnect it to another 
giving it a new device name and the array should not even need to sync.

Somehow it doesn't. Somehow the array remembers of which devices it's supposed 
to be assembled and boots in degraded mode, funnily not always missing the 
swapped drive.

Suppose I lose a whole ide-controller and want to restart the box with a 
seconday controller? That one would surely not have the devices hda through 
hdd and my array would refuse to start.

Does anyone have a suggestion of what I can try? Ok, the array runs fine as 
long as it is connected to its original bus, but I really don't want to take 
chances here.
