I wonder if there's any way to do this. Say there are two different storage devices mounted as follows:
/slow-hard-drive/email-directory /fast-ssd-drive/email-directory
Now suppose there were a way to join these drives so that you could access them as a single directory:
/joined-drive/email-directory
The Dovecot could see the joined drive but my backup/archiving scripts could see the drives independently and move old data from the fast drives to the slow drives.
I think back in the old DOS days you could do that. Is there a way in Linux to do the same thing? Join two directories so as to make them look like one?
This is getting rather far from Dovecot, but I believe you're looking for unionfs: http://en.wikipedia.org/wiki/UnionFS
