Full Discussion: Cannot remove root Filesystem from the Multipath configuration
Operating Systems Linux Red Hat Cannot remove root Filesystem from the Multipath configuration Post 302885504 by logsbyrne on Monday 27th of January 2014 04:58:48 AM

Hi, many thanks for the reply.
We have tried that already, no success.
I have also blacklisted the WWID in the multipath.conf and still no success.
There is one curious thing however. When we re-read the new configuration, although the root filesystem is still listed, it only appears to have one path now.
I wonder if this is a red herring.
See output from 'multipath -ll' below.
The root filesystem is labelled 'mpatha'
