If you come across the below error on a server running with Intel Matrix (Software - Onboard) RAID, it generally means that you will need to exclude the device within /etc/lvm/lvm.conf as it cannot be backed up.
Could not find MD Device '/dev/md0' in the list of devices returned from the agent
In the above example, /dev/md0, is actually a software raid partition, and does not need to be backed up, as you manually create it in the case of a baremetal restore.
In order to resolve this, you would modify the filter line within /etc/lvm/lvm.conf from
filter = [ "a/.*/" ]
filter = [ "a/.*/", "r|/dev/md0|" ]
You can check that this change is valid, by running vgscan after you have completed these changes.
This should silence the above error in future replications.
