If exactly half or more of the expected votes disappear, a quorum no longer exists (except in the two-node special case).
The voting values cam be seen with a # cman_tool status If there is quorum, and exit code of 0 (zero) should be returned to the shell wht the clustat -Q command (which produces no output) is run; # clustat -Q # echo $?

I've been tasked to take down the cluster and divide the content of the shared GFS filesystem to the local disks on each system with minimum downtime. I've removed two nodes from the cluster already and am somewhat scared of a quorum problem if I remove another node. >From what I've been able to gather I should use cman_tool leave remove on a node once it is ready to leave the cluster and thus be able to remove four nodes from a five node cluster without disolving the quorum or risking losing access to the GFS data on the last remaining node. Is that correct ? With best regards, -- Saevaldur Arnar Gunnarsson System Administrator | RHCE Hugsmidjan ehf.
