Example:
11 nodes (votes are 2 nodes @ 5 each, plus 9 nodes @ 1 each, expected = 19, quorum = 10)
"leave remove" 1 node @ 5 votes, quorum re-calculates as 8, total = 14
"leave remove" 1 node @ 1 vote, quorum re-calculates as 7, total = 13
"leave remove" 1 node @ 1 vote, quorum re-calculates as 7, total = 12
"leave remove" 1 node @ 1 vote, quorum re-calculates as 6, total = 11
"leave remove" 1 node @ 1 vote, quorum re-calculates as 6, total = 10
"leave remove" 1 node @ 1 vote, quorum re-calculates as 5, total = 9
"leave remove" 1 node @ 1 vote, quorum re-calculates as 5, total = 8
cman join 1 node @ 1 vote, quorum re-calculates as 10, total = 9, inquorate!!
Please advise, thanks.

Thanks for this Lon, I'm down to the last two node members and according to cman_tool status I have two nodes, two votes and a quorum of two. -- Nodes: 2 Expected_votes: 5 Total_votes: 2 Quorum: 2 -- One of those nodes has the GFS filesystems mounted. If I issue cman_tool leave remove on the other node will I run into any problems on the GFS mounted node ? (for example, due to quorum) On Mon, 2007-10-29 at 10:56 -0400, Lon Hohberger wrote: > That should do it, yes.
