[Gluster-users] Gluster 3.6.4 peer rejected while doing probe

Mon Sep 14 05:43:00 UTC 2015

Davy,

This seems to be an issue which we also faced couple of months back
during upgrade testing and a bugzilla [1] was raised for the same. At
the time we didn't have the work around to make peer probe work, but
somehow I managed to get the workaround today.

Could you do an explicit volume set on the existing cluster and then do
a peer probe? Let me know if that works.

Thanks,
Atin
