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 ?
