gluster peer probe failed: <node> is either already part of another cluster or having volumes configured

I have 2 gluster clusters of type distributed-replicated:

Cluster 1 (C1): with bricks in machines M1 and M2.

Cluster 2 (C2): with bricks in machines M3 and M4.

I want to expand C1 by adding M4 (already part of C2) and another machine M5.

For adding the bricks, first I need to add M4 and M5 into C1 by probing M4 and M5 from either M1 or M2. When I do peer probe, I am able to add machine M5, but when I try to add M4 to C1 by

sudo gluster peer probe M4

I get:

peer probe: failed: M4 is either already part of another cluster or having volumes configured

I have two questions:

  1. Is it even possible to achieve what I want (since I am mixing two different clusters)?

  2. If yes, how to do it?

PS: I have read the following links but my issue still is not resolved: redhat mailing list, redhat mailing list-2

Please run 'gluster peer detach ' on every hosts. Then try 'gluster peer probe

On the rejected peer:

  • Stop glusterd

  • In /var/lib/glusterd, delete everything except glusterd.info (the UUID file)

    rm -rf !(glusterd.info)

  • Start glusterd

  • Probe one of the good peers

  • Restart glusterd,

  • check 'gluster peer status'

You may need to restart glusterd another time or two, keep checking peer status.
