"error 28 from storage engine" during Rails deployment

Question

I have been deploying fine with no problems. Today I got this error...

rake aborted!
Mysql::Error: Got error 28 from storage engine: describe active_admin_comments

Why? How?

Answer 1

You might be low on disk space on your deployment server. Check the results from df -h to see if any of your filesystems are low on space (especially /tmp).
