The problem is that when you move LV's around and make snapshots the bad
blocks on the underlieing media will move. Therefore I think that management
of bad blocks possibly should be done in the LVM.
Or should we just assume that LVM runs over RAID arrays of ATA/SCSI disks
that have sector-sparing so that bad blocks are not an issue?
