June 27, 201214 yr I am surprised this has not been requested before which makes me think there is some technical gotcha I am missing. Currently unRAID has a bit of a fit if the drives move about. i.e. if you move drives to a different slot/port. Unfortunately for many reasons this can happen even if you don't actually move a drive i.e. kernel changes or adding a new drive Since the parity XOR does not care about order why does order matter?
June 27, 201214 yr Older versions of unRAID used the disk controller port to tie a given "slot" in the array to a drive. As long as you used the same set of ports, it usually figured things out. It did not use the actual /dev/sd? or /dev/hd? device names. Newer versions of unRAID, (since 5.0-beta8 I think) use the disk model/serial number to tie a given disk to a 'slot' in the array. As long as the model number/serial number of the disk does not change, it is able to figure things out. Are you looking for something in addition? I'm thinking the feature you are requesting is already there.

No it doesn't ... unless I'm misunderstanding what you are asking for. I have stopped the array, hot-swapped drives to different slots in my 5in3 cages (even on to different controllers) and restarted the array. The array comes up and runs as though nothing has changed. This works with any of the more recent 5.00 betas/RCs.

It definitely does not care about order anymore.
