XFS tip:

If you truncate a file it doesn't update metadata. That's how you can get back space for the journal log to start cleaning up crap without rebooting the box and/or taking services down.

My initialisation script creates five 100M files in /root (which is on /) to give something to manually delete for breathing room.

Thank you, I’ll keep this in my hat for the next time.
