Hi Daniel,
Are you sure that all data directories are writeable by the Cluster
processes on the coresponding hosts?
What's in the cluster log? Looks like that should be
/var/lib/mysql-cluster/ndb_1_cluster.log on the management server host.
Some other potential issues:
1. Looking at the IP addresses in your configs makes me suspect you're
trying to set up a cluster over the Net. If this is what you're doing,
this is almost certainly not going to work. Cluster requires 100 Mbps
connectivity. The most sensible setup uses a dedicated subnet.
2. Note that FreeBSD is not listed on
http://www.mysql.com/support/supportedplatforms/cluster.html. This is
due in part to the fact that there are known issues with building MySQL
with NDB support on FreeBSD that have only recently been fixed. These
fixes are not yet in any published release, and they've not yet
propagated to the ndb-6.2/ndb-6.3 trees - you'll need to pull and build
the latest 5.1.24 source from mysql.bkbits.net for these.
Good luck!
jon.
