That makes sense. However, using the original physical drive, I get the
same result. I'm perplexed. Here's the same result after trying assembly
with --scan
# IMSM_NO_PLATFORM=1 mdadm --incremental --run -v /dev/md/imsm0
mdadm: /dev/md/imsm0 is not part of an md array.
Here are the relevant lines from letting --scan do the assembly of the
container, in case that gives a hint ("no correct container type"
interesting?). What else could I do?
# IMSM_NO_PLATFORM=1 mdadm --assemble -e imsm -v --scan

mdadm: /dev/sdc is identified as a member of /dev/md/imsm0, slot -1.
mdadm: added /dev/sdc to /dev/md/imsm0 as -1
mdadm: Container /dev/md/imsm0 has been assembled with 1 drive

mdadm: /dev/md/imsm0 is a container, but we are looking for components
mdadm: no correct container type: /dev/md/imsm0
I also tried with the bad physical drive and it had the same result. Then
I attached both of the original drives and still no luck. The only
difference was:
mdadm: /dev/sdd is identified as a member of /dev/md/imsm0, slot -1.
mdadm: /dev/sdb is identified as a member of /dev/md/imsm0, slot -1.
mdadm: added /dev/sdb to /dev/md/imsm0 as -1
mdadm: added /dev/sdd to /dev/md/imsm0 as -1
mdadm: Container /dev/md/imsm0 has been assembled with 2 drives
But the volumes are still not assembled.
