Thanks for the pointers to the status of convert.  This is not critical
data, so it's alright even if something goes wrong.  Your rsync options
will be very helpful for a future move to btrfs for my /.

In the meantime, I managed to resolve my problems.  I have several
multi-GB files on this drive, I had deleted a few large files from the
gui (meaning, they were still in lost+found).  That's when the problem
started.  I could see them in the l+f, but could not remove or restore
them.  Since the filesystem was rw for the first few seconds, I resorted
to a kludge: mount and try to empty the l+f before it turns ro, unmount,
rinse repeat.  Each time I tried, I removed a few of the files.  It took
me maybe 4-5 tries to clean about 10 files.  Ever since I did this, I
have had no problems.  I plan to run a scrub sometime soon, maybe
tonight.

Thanks again, without your warning, I might have run convert on my /.

Cheers,
