"dmsetup remove --force" does not appear to work. "dmsetup table" is an
output command. I don't see how to do what you suggest. I see a
command to load a table into the "inactive table slot" for a device, but
not a command to actually change the active table.
Really, this idea is too far above my head. For now I'm going to go
with "fuser -km /mountpoint" followed by a reboot if umount fails. If
you have a better idea involving the device mapper, please use small
words.
