Opening a ticket so that the bug can get fixed would be a better choice. 
MythTV should only auto-expire from filesystems which needs space. A not 
mounted filesystem with not enough space in the root fs shouldn't cause 
autoexpirer activity since there are no expirable recordings on the 
filesystem (since there are no recordings at all).

The storage group code can handle missing mounts gracefully if you 
specify a directory under the mounted filesystem in the storage group. 
E.g. if your HDD with the recordings is mounted to /video create a 
directory /video/recordings and use that in mythtv-setup. If /video 
fails to mount mythtv will detect that /video/recordings is absent and 
doesn't use it.

ps: please try to describe your storage setup as precise as possible 
when opening the ticket
