I have been doing it on FC4. Even when I had a drive failure (not the
drive in the end), it was an easy repair as the RAID dropped the bad
drive and notified me. Heck, I didn't even know that the drive had
failed. I did panic but it turned out that it was no big issue.
As media files get more and more demanding, I love LVM. No moving
around mount points to allow enough storage space for all those media files.
