Red Hat Bugzilla – Bug 161227
Specifying root filesystem in grub via UUID
Last modified: 2010-10-21 23:05:55 EDT
Description of problem:
There are merits of specifying root filesystem in grub using UUID since disk
label doesn't fit the need. For example, in a real world case, when a panic
system got rebooted, it picked up the wrong lun (root partition) from the shared
SAN since someone just newly created a new root partition (lun) for another host
using the very same disk label. It took a while to figure out what went wrong
because the system was panicked before that reboot.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
UUID has the downside of being completely incomprehensible to a user :)
LABEL is the best compromise between something that can be understood and
something that is relatively resilient to disks moving around.
REOPENED status has been deprecated. ASSIGNED with keyword of Reopened is preferred.
