That's right but based on our earlier email exchanges for the other issues
you reported I believe when a board is restarted the content of
/var/lib/glusterd/ gets wiped off which will also delete glusterd.info
file, isnt that true? Honestly with this data, its not possible to analyze
the issue. You'd need to give us the glusterd log from all the nodes to
progress on it further.
