Red Hat Bugzilla – Bug 166973
Upgrade fails on multipath RAID devices
Last modified: 2007-11-30 17:07:20 EST
Description of problem:
Upgrading a system on a multipath RAID array, created on RHEL-3-es, fails
completelly. It is necesary to remove the labels from the filesystems and alter
fstab for the installation to proceed.
Version-Release number of selected component (if applicable):
RHES-4 installation CD
Steps to Reproduce:
1. Create a multipath RAID with RHES-3 on it.
2. Try to upgrade.
3. Installation compalints about duplicate labels.
Can't upgrade without putting system upside down.
Usual smooth upgrade.
anaconda doesn't have any support for multipath, so to do an upgrade, you have
to get down to a single path situation.

I've already deduced that. Turning back to a single path situation is not a nice
task in a complex environment like a blade center conected to a Fibre Channel
fabric, and it would be nicer to your paying customers, and probably easier, to
get multipath into the installer kernel and some intelligence, rather than
forcing your customers to downgrade a perfectly functional system.
