Default gfs_controld: full check for member changes

On 09/28/2011 12:37 PM, David Teigland wrote:

cman members are queried in response to a callback,
and members sometimes leave and rejoin between queries
(e.g. when they leave and rejoin before corosync
detects they left.)

This means that simply checking if a node is a member
in consecutive queries sometimes misses events. We
need to compare the incarnation numbers of members
from consecutive queries to avoid this.


ACK
