how can we setup 3 node master master cluster in one data center ?

Can Anyone help in this to resolve ?

Starting Master

./bin/yb-master
–master_addresses 10.151.16.189:7100,10.151.16.199:7100,10.151.16.119:7100
–rpc_bind_addresses 10.151.16.119
–fs_data_dirs “/u01/yugabytedata/disk1,/u01/yugabytedata/disk2”
–replication_factor=3

Can you follow this guide here: Manual deployment of YugabyteDB clusters | YugabyteDB Docs

Hi Already following yugabyte docs.

When I am starting yb-master we are getting below errors.

Hi @BijalShah01

Did you try stopping the yb-masters, emptying the data dirs, and starting them again like I wrote you on slack ?

yes …i already did it.
