Comments - Does MariaDB Galera Cluster 10.0.21 version support gmcast.segment?

gmcast.segment is not a dynamic galera parameter, so it has to be set via the config file.

Changing it using SET command would lead to the following error in the error log:

151217 12:02:10 [Warning] WSREP: error setting param gmcast.segment to value 1: can't change value for 'gmcast.segment' during runtime: 1 (Operation not permitted)
