Description Mike Christie 2018-03-29 21:20:04 UTC

Description of problem:

The rbd checker in multipath tools is no longer used be RHCS and upstream.

It's use when used with lio and krbd's exclusive lock can lead to data corruption, and the ceph team has gone a different way using lio and tcmu-runner.

This is a request to drop it from multipath-tools.
