I'd like to setup two servers to have a clustered data source, I've seen different documentation telling me that I'll need at least three servers because I would also need a management server. I've also read that the management server is not neccessary after the cluster has been started or even after initialization.

My test setup includes two vmware virtual machines running on a private lan. I've also setup one of them to be the management server and of course I get the warning that running the arbitrator and one cluster node on the same host is not a good idea.

Now when I reboot the vm with the ndb_mgmd the other node gets an error and shuts down due to a cluster failure. This is not cleanly reproducable but happens at least in 75% of all reboots.

The logfile tells: Date/Time: Tuesday 18 January 2005 - 07:37:58 Type of error: error Message: Arbitrator shutdown Fault ID: 2305 Problem data: Arbitrator decided to shutdown this node Object of reference: QMGR (Line: 3796) 0x0000000a ProgramName: /usr/local/libexec/ndbd ProcessID: 4220 TraceFile: /var/cluster/db1/ndb_2_trace.log.4 ***EOM***

The tracefile is available here: http://www.hayai.de/misc/ndb_2_trace.log.4.bz2

Any help would be appreciated, regards, Marco
