I am very interested in hearing more details about this.   There is a
cluster which I wish to upgrade/clean-install  to version 1.8.3 or
1.8.4 (currently 1.6.7) and I desire to use both LVM and multipathing.
  The current set-up does use multipathing but not LVM.   I was hoping
to introduce LVM into the new build to enable more efficient snap-shot
backups and expandability on the MDT disks.

Do you know what the conflicts are with the multipathing and LVM?
Was the case-in-point multpathing and LVM on MDT volumes or other?

I appreciate your kindness in sharing your experience.

Sincerely,
megan
