[mythtvnz] File System for RAID-5

Consider doing none of that.

Consider a RAID1 for your system drives, and all the other drives in a
mythtv storage group.  Programs will be written to individual drives, and
if any one dies it will not take out the others.

If you raid5, then you loose a drive worth of storage, and remember its
only TV.  Not your critical personal data.

I suggest jfs because it has predictable fsck/mount times.  Something like
ext3 will someday jump at boot and demand a fsck taking hours and hours.
