I have a failing drive, and partitions are in multiple arrays. I'm
looking for the least painful and most reliable way to replace it. It's
internal, I have a twin in an external box, and can create all the parts
now and then swap the drive physically. The layout is complex, here's
what blkdevtra tells me about this device, the full trace is attached.

I think what I want to do is to partition the new drive, then one array
at a time fail and remove the partition on the bad drive, and add a
partition on the new good drive. Then repeat for each array until all
are complete and on a new drive. Then I should be able to power off,
remove the failed drive, put the good drive in the case, and the arrays
should reassemble by UUID.
Does that sound right? Is there an easier way?
