Hello,
I am trying to figure out when a galera node is able to serve requests so
the load balancer can direct traffic to it.
Right now I am using a check to get the galera status number and if it is 4
(SYNCED) I consider it able to serve requests.
The issue I am having is when I run the daily backup using xtrabackup. In
the last 5 mins of the backup when everything gets locked and the
transaction log is streamed it seems the other nodes do not serve requests
either although there is nothing logged about it and if they are affected
by locked node.
Kind Regards,
Ilias.
