[ERROR] WSREP: Unrecognized parameter 'gmcast.segment'

Hello all

I have added the below to my.cnf

wsrep_cluster_address = gcomm://
wsrep_node_address = 10.76.199.226
wsrep_node_incoming_address = 10.76.199.226
wsrep_provider = /usr/lib64/libgalera_smm.so
wsrep_provider_options = “gmcast.segment=1”

It does not start up the cluster anymore stating the below error:

[ERROR] WSREP: Unrecognized parameter ‘gmcast.segment’

What version of PXC are you using? It looks like you’re using an older version and so that variable does not exist in the version that you are using. As per http://galeracluster.com/documentation-webpages/galeraparameters.html , that parameter is available for Galera 3+
