Ok, it just sounded like you were definitely against xfs. Certainly when I
originally looked at Myth there wasn't really any word about what to use
(other than that ext2 was problematic). From a quick look at the wiki and
the install doc it still doesn't look like there is any sort of
recommendation. I chose xfs because the delete performance was practically
the same as jfs, but overall performance was better. ISTR at the time jfs
was considered a little less mature on linux as well.

I do let the filesystem fill up fairly regularly (as I don't use
auto-expire). The only problem I've had with this is that it makes the
frontend (and mythweb) fail to display the list of programs so that I can
delete one. What I usually do is to move a file to another disk, then delete
stuff as usual, and finally replace the file I moved. A little inconvenient
but no real issue for me.

Cheers,
Steve
