Cannot remove root Filesystem from the Multipath configuration
Hello all,
I am running "Red Hat Enterprise Linux Server release 6.4 (Santiago)"
The root Filesystem is currently part of the Multipath configuration and I need to remove it without rebooting the production Server.
The wwid I want to remove from Multipathing is the last one i the list of wwid's below, i.e. 3600508b1001c5c8ef3f93243d9a1bd41
I'll provide the files I think might be required. Any help would be great.
Code:
