Don't do that - take the second node out of the cluster whilst the
other node(s) are still running, so that they can see it leaving.

</div>
<div>Thanks you very much for this information </div>
<div>another problem i am facing is i have two nodes clustered
lets say rabbit@SHIKHARM(ram) and rabbit@CHETANDEV(disc)</div>
<div>now if i stop rabbit@SHIKHARM using rabbitmwctl stop command
and then i stop rabbit@CHETANDEV using stop_app command and
then reset it this way i remove it from cluster and restart the
node </div>
<div>now rabbit@CHETANDEV starts and works fine but when i try to
start rabbit@SHIKHARM it fails .</div>
<div>i think it is trying to cluster with rabbit@CHETANDEV but
that node is now not in cluster but is there a way so that i can
reset rabbit@SHIKHARM and start it normally</div>
<div>here is the error that i got: </div>

looking at the 3.0 cluster commands I'd forgotten that the
choice of disk/ram was done that way in 2.8.x.<br>
