Re: Mariadb 10.1.6, total cluster recovery - gvwstate.dat
If I kill -9 mysqld on all three of my nodes in the cluster, then start the
services simultaneously,the cluster comes back online successfully using
the gvwstate.dat file.
If I gracefully shutdown mysql on all three nodes as you mentioned the
gvwstate.dat file is deleted. This means when the cluster needs to be
restarted I am forced to edit my.cnf and replace
wsrep_cluster_address=gcomm:// on one of the nodes before I can bring up
Is there anyway to have the last node that is shutdown gracefully keep it's
gvwstate.dat file so that the next time the cluster is started it can come
online without editing the config file?
