At 18:01:34 (after 15 hours and change) I decided to give it up and
sent tune2fs a SIGINT. It happily aborted, and fsck appears to have
fixed whatever inconsistencies were introduced during the tune2fs run
and the files on the volume appear to be perfectly intact.
Am going to go the route of simply pulling the data off and using
mkfs.ext4 to create a new filesystem on the device. But, I am still
curious as to why this would run for so long. Some volume statistics,
in case they may be of help in trying to determine why this process was
running for so long; I don't even know how much longer it would have
run for.
