[Gluster-users] peer rejected but connected

[lejeczek]

hi fellas,
same old same
in log of the probing peer I see:
...

Why would adding a new peer make cluster jump to check 
checksums on a vol on that newly added peer? Is it why the 
peer gets rejected?
That peer I'm hoping to add, was a member of the cluster in 
the past but I did "usual" wipe of /var/lib/gluster on 
candidate peer.

a hint, solution would be great to hear.
