Description
I installed vanilla MariaDB 10.1.37, and enabled wsrep library.
When I checked default wsrep_provider_option setting, found some wrong points :
(1)
"evs.suspect_timeout" default value (PT5S) is different from reference manual :
https://mariadb.com/kb/en/library/wsrep_provider_options/#evssuspect_timeout
> Default: PT10S
(2)
The magnitude correlation among "evs.suspect_timeout" and "evs.inactive_timeout" and "evs.install_timeout = PT7.5S" is deffer from the codership manual recommendation :
http://galeracluster.com/documentation-webpages/configurationtips.html
recomended :
evs.suspect_timeout < evs.inactive_timeout (default : 15sec) ≦ evs.install_timeout (default : 15sec)
MariaDB default:
|
evs.suspect_timeout < evs.install_timeout (default : 7.5sec) < evs.inactive_timeout (default : 15sec)
|
MariaDB [(none)]> show global variables like "wsrep_provider_%"\G
