Hi managers,
I've got a three node 5.1B memory channel cluster of which one node is
deliberately down.
So that the remaining two nodes can be shutdown independantly, I've
adjusted the expected votes and quorum disk votes such that I don't lose
quorum, as shown by the following clu_quorum output.
# clu_quorum

I now want to remove the third member from the cluster altogether.
Does clu_delete_member take account of the manual vote adjustments I've
made, or will it try to adjust the expected votes based on the file
value of the third node - which will (I think) make me lose quorum...?
In case its relevant, its not an option to bring the third node back up,
but its boot_partition is mountable.
Cheers,
Rob
