My attempt to get a software RAID-based test bench set up are going about as well as expected…
- /usr is too small?! Back up and try again.
- inadvertently click the wrong arrow; wait 1 hour for badblock scan to complete (again).
- Can’t back up far enough to change partitions; start over.
- Attempt “upgrade” option, which fails; start over.
- Bad blocks detected on resized sda7; start over.
It finally worked. Elapsed time: about 6 hours. Networking fails, though, which is par for the course. Hmph.
