We need a "locator"; something that can take a device name and blink the
activity LED at a regular rate.  This could be "tricky" with a failed
drive however (because you don't really want to read from it).  Will the
activity LED blink for other actions on typical drives?  I know the LED
on some CD drives will blink when checking to see if media is in the
drive.

This is a problem, especially at boot.  You can also have problems with
LVM if you have drives with different volumes on them that have the same
name.  I always name my volumes based on the host name instead of
LogVol00.

Mount by UUID instead of by label should solve the first problem, but it
doesn't help with LVM.
