1. sw-raid arrays - how do you not rely on device names when trying
to
fail-out a drive?
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.
2. adding a new disk to a system. The new disk has been a boot disk
for
another older system. Suddenly you have two partitions labeled /
and /var. How do you get out of that w/o booting up and making fstab
mount via device name?
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.
