I just started going through the log files you shared. I've few
questions for you looking at the log:
1. Are you sure the log what you have provided from board B is post a
reboot? If you claim that a reboot wipes of /var/lib/glusterd/ then why
am I seeing that glusterd has restored value from the disk files?
2. From the content of glusterd configurations which you shared earlier
the peer UUIDs are 4bf982c0-b21b-415c-b870-e72f36c7f2e7,
4bf982c0-b21b-415c-b870-e72f36c7f2e7 002500/glusterd/peers &
c6b64e36-76da-4e98-a616-48e0e52c7006 from 000300/glusterd/peers. They
don't even exist in glusterd.log.
Somehow I have a feeling that the sequence of log and configurations
files you shared don't match!
