Could not find MD Device '/dev/md0' in the list of devices returned from the agent

Follow

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/.*/" ]

to

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.
