Recovery help needed for remote server: file system mounted read-only

[Tom Browder <tom.browder@gmail.com>]

I've had this problem a long time ago, and don't remember how I recovered, but it was with help here.

I suspect a failing disk, and I wonder if there is a hail Mary command I can do to force a reboot to see if it can recover on its own. I would almost welcome starting over with a new server.

I can login and su to root. I have not been able to inspect logs yet due to time.

I see a 2023 Debian thread getting into lots of low-level fsck and other things, but  can my old brain and trembly fingers hack it without compounding the problem?

Opinions requested, please.

Oh, I do have backups of my important stuff.
