Well, maybe you won't lose *everything*... but what's happening there
is roughly that you're using the LVM software drivers to emulate RAID-0
longitudinal striping, and then putting *one* filesystem on top of it.
If one of those drives blows, you're going to have a 200GB hole in the
middle of your 1TB filesystem, and yes, fsck will probably not be happy
There has been intermittent talk over the last couple years about
making MythTV know how to deal with multiple media storage directories.
I haven't been following either list too tightly, so I don't know
what's come of that topic lately. Anybody know?
