[Maria-discuss] Designated donor.
Hi, I want to configure my cluster of 3 nodes let's call them sql1, sql2, sql3 in the way that maxscale will only balance request to sql1 and sql2 but sql3 will be only for backup/donor purposes. My question is... how can I set permanent donor in galera ? Is wsrep_sst_donor the thing ? Thank you. Regards, TH
That's correct. wsrep_sst_donor takes a node name as argument: wsrep_sst_donor=sql3 GL On Wed, Jul 6, 2016 at 12:00 PM Thorvald Hallvardsson < thorvald.hallvardsson@gmail.com> wrote:

Don't get the donor name wrong or you'll be chasing phantom network error messages. https://github.com/codership/galera/pull/109 On 06/07/16 20:00, Thorvald Hallvardsson wrote:

Hi, Thanks all. What should I configure on sql3 then as a donor ? Or shall I leave this option unset ? Thank you! Regards, TH On 7 July 2016 at 07:11, Daniel Black <daniel.black@au1.ibm.com> wrote:

i couldn't make wsrep-sst-donor work with either the ip addresses from the gcomm:// wsrep_cluster_address in my.cnf or with the host names wsrep wrote in the log. i concluded i couldn't use it. tom
It needs to match https://mariadb.com/kb/en/mariadb/galera-cluster-system-variables/#wsrep_nod... of the donor. On 08/07/16 10:59, Tom Worster wrote:
