So, if md4 is the underlying device for your drbd devices, when lvm2 scans /dev looking for labels it finds the label on md4 first and uses that. You can control this using lvm2's filtering options. See the man page for lvm.conf for the full details, but editing /etc/lvm/lvm.conf and changing the filter line from: filter = [ "a/.*/" ] to: filter = [ "a|/dev/drdb|", "r|/dev/md|", "a|.*|" ] Should accept all drdb devices as physical volumes, reject any software raid (md) devices, and accept everything else. This should work if you only have PVs on drdb or other device types and not on any plain md devices. If you have a mix of the types you will need to create a more specific filter line for your system.

    /dev/md4 is the raid device over was configured drbd0.

    Why /dev/md4 it's taken as PV Name?

    

It's trying to be helpful! Normally people build MD devices out of other devices
and so LVM uses the MD in preference to other devices it finds with the same UUID.

You'll need to exclude the MD device in the /etc/lvm/lvm.conf filters entry.
something like:

filter =[ "r/md4/" ]
