Default Encfs suddenly read-only -- DISK FAILURE

I rebooted Sunday morning (it's a ~amd64 system) to change kernel to 3.3.5 from 3.3.4, and sometime overnight, after the nightly backups and mail archives had run, the encfs mounted partition became read-only. I know the timing only by the cron jobs; the nightly mail backup moves files from the /home partition to the encfs partition, and it had not failed. I unmounted the encfs partition, remounted, and it was read-only right from the get go.

It's a failing disk drive:

I didn't see it the first time because I rebooted twice and only looked since the second reboot, after spending a while googling for hints and forgetting about the double reboot.
