I use Cyrus on XFS and I've noticed that, for example, the SEEN database
can get truncated if you accidentally run out of space. I assume that
this happens on other file systems as well, but I've never tried it. In
fact, I hope to never try it on XFS again either. ;-)

I was using a Cyrus 2.2 on Debian Lenny at the time so I'm perfectly
happy to concede that this may well have been fixed a long time ago.
My databases will have been in skiplist format and I managed to recover
them by dumping and reloading with the information I found here:
