    I set them inside mysql client as such

     

    mysql> SET GLOBAL wsrep_provider_options="evs.keepalive_period = PT3S; evs.suspect_timeout = PT30S; evs.inactive_timeout = PT1M; evs.install_timeout = PT1M";

    Hi

    Only evs.install_timeout is a dynamic variable that you can set via a "set global". The others you need to persist in the my.cnf file and restart the nodes.

    Where are your wsrep_NNN variables saved, in the my.cnf file or elsewhere?

    Do you have a !includedir in your my.cnf file? Then look in that directory for a separate file with wsrep_NNN variables and edit/set the wsrep_provider_options there for all the nodes and restart them one at a time (rolling restart).

    Hi Alex

    Actually I see they got set when I ran the command I posted above

     

    # mysql -uroot -pXXXXX -e 'SHOW VARIABLES LIKE "wsrep_provider_options"'

    Hi

    It might be set in the wsrep_provider_options variable but I'm not sure if has taken effect.

    Any errors/warnings in the mysql error log file?

    According to the reference manual, http://galeracluster.com/documentation-webpages/galeraparameters.html for example evs.keepalive_period is not a dynamic variable.

    hi Alex

     

    I don't see any errors or warnings but better to do it properly

    Can I set all of them in my.cnf ?
    This is where the rest of wsrep variables are


    Ok to set them like this?

    wsrep_provider_options = "evs.keepalive_period = PT3S"
    wsrep_provider_options = "evs.suspect_timeout = PT30S"
    wsrep_provider_options = "evs.inactive_timeout = PT1M"
    wsrep_provider_options = "evs.install_timeout = PT1M"


    Parameters that are already in my.cnf

    wsrep_provider=/usr/lib64/galera-3/libgalera_smm.so
    wsrep_cluster_address="gcomm://10.10.1.11,10.10.1.12,10.10.1.13"
    wsrep_max_ws_rows=1048576
    wsrep_max_ws_size=1073741824

     

     

    Thank you for your help

    Thank you. I added them to all nodes my.cnf and restarted mysql one after the other.

    Appreciate your help.
