I have an overnight cron job with
/sbin/fstrim -v /
/bin/bedup dedup --defrag
Every once in a while, it causes the FS to be remounted read-only.
Problem is pretty intermittent so far (aside from a few kernel revisions
a while ago).
Please advise.

Probably not related, but these look backwards, why not reverse them?

Thanks, will do that. Anything else useful I could add to the cron job,
btw? I was thinking maybe a scrub operation to check for errors..

You might want separate jobs. fstrim should be done when the SSD isn't busy (or about to be), and you could do that maybe once a week. And scrub followed by deduplication maybe once a month. Separately schedule smartd to do extended offline test.
