+1 on LVM.

My preferred configuration puts LVM on top of RAID; a single RAID
array becomes a single LVM PV and VG.

btrfs is getting close, for me, but I'm not going to take the plunge

it...but I haven't read through any literature for good practices and
error recovery for btrfs/zfs-style setups.
