Hello, A new question has been asked in "Galera" by uxbod: -------------------------------- We have MariaDB and Galera working in our lab on a three node cluster. When setting them up the wsrep options for each node were as follows: {{{ node1: wsrep_cluster_address="gcomm://" node2: wsrep_cluster_address="gcomm://172.30.1.3" node3: wsrep_cluster_address="gcomm://172.30.1.1" }}} Once all the nodes were in sync I shutdown node1 and set its wsrep_cluster_address to be 172.30.1.2. This I thought would allow the three nodes to keep in sync. What happened though was when I started MariaDB backup I received the error: {{{ 130702 8:35:51 [ERROR] WSREP: Local state seqno (16053) is greater than group seqno (15898): states diverged. Aborting to avoid potential data loss. Remove '/var/lib/mysql//grastate.dat' file and restart if you wish to continue. (FATAL) at galera/src/replicator_str.cpp:state_transfer_required():34 }}} Why has this happened ? Is it safe to proceed with the recommendation of removing grastate.dat ? -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/local-state-seqno-out-of-sync-with-group/
