Hi Antonio,

 Could you please share your config.ini file? I'd like to check that your ndb_mgmd process
is not running on the same host as one of your data nodes.

 Setting StopOnError to FALSE will tell the data node's agent to restart an ndbd process
if it is killed.

Regards, Andrew.

Subject: Cluster crash after datanode shutdown

Hi,

I setting up a mysql cluster with 2 data nodes and 1 management node. I was testing its
reliability by shutting down a node and making some queries in the alive one, when I was
testing with a small database, it worked well, independently of the data node I turned
off, it kept running. The problem is when I import my radius database to it (about
1.5GB), if I turn one of the data nodes off, the cluster stops and I receive this
message:

Node 3: Forced node shutdown completed. Caused by error 2305: 'Node lost connection to
other nodes and can not form a unpartitioned cluster, please investigate if there are
error(s) on other node(s)(Arbitration error). Temporary error, restart node'.


I've seen in some lists the people recommending to enable the StopOnError attribute, but I
don't know its side effects.

Thanks.
