panic closing diskHealthCheckingFile

[dankinder]

I have a node that died and now won't come back up due to this error, it crashes right away. Cockroach V22.1.11. This is when trying to open pebble on a file system that has gone read-only.

Not that I'd expect this to succeed, but it might fail a little more gracefully than "close of closed channel".

panic: close of closed channel [recovered]

It originally crashed due to disk stall, when the file system for this disk decided to go read-only:
