I have been working on configuring multipath on a couple of RHEL 6 servers. Through some fault of my own (blacklist mistyped) I have configured multipath on the root partition, yet it seems that I am having trouble undoing that. The root partition is not on a SAN. It is a local, RAID 1 drive set.
Any help would be appreciated.
Attempted to change to hard paths in fstab (sda1, etc) from UUID based paths. This brings up unbootable and in rescue mode. I didn't, however, alter the grub.conf with the same change, so I am wondering if that would do it?
Attempted to remove multipath entirely. Had to boot in rescue mode, start networking and reinstall.
Of course tried "multipath -F", but root is in use at the moment.
Haven't tried any of the above with the rescue disk, as this is a remote system and loading a cd isn't that easy, but I can manage getting it done if that is the only option.
