GlusterD doesn't generate a new UUID on init if it has already generated
an UUID earlier. This clearly indicates that on reboot of board B
content of /var/lib/glusterd were wiped off. I've asked this question to
you multiple times that is it the case?
Yes I am following the same which is mentioned in the link:
http://www.gluster.org/community/documentation/index.php/Resolving_Peer_Rejected
http://www.gluster.org/community/documentation/index.php/Resolving_Peer_Rejected
but why it is showing two peer enteries?
This attachment doesn't help much. Could you attach full glusterd log>
