Shouldn’t we expect to see the qdisk votes reported in “Total_votes”
from cman (see cman_tool below). If we have four nodes with 1 vote each
and a qdisk configured with 1 vote (see cluster.conf snippet below)
shouldn’t we see a total vote count of 5? With the qdisk config shown
below I would expect to be able to sustain a loss of 2 out of 4 nodes
and still have quorum but in fact the loss of 2 nodes dissolves quorum
every time, effectively locking the cluster.
Thanks,
Dan
