How to clean?
This is caused by active lvs on the remove storage domains that were not deactivated during the removal. This is a very old known issue. You have remove the remove device mapper entries - you can see the devices using: dmsetup status Then you can remove the mapping using: dmsetup remove device-name Once you removed the stale lvs, you will be able to remove the multipath device and the underlying paths, and lvm will not complain about read errors.
