Hi !
We have running MySQL Cluster (ndb-7.3.2) with follow configuration:

and /etc/my.cnf (at nodes):

[mysqld]

ndb-connectstring=78.140.152.136

[mysql_cluster]
ndb-connectstring=78.140.152.136

After cluster's restart whole cluster gone down during start process with this error:
Time: Thursday 14 November 2013 - 03:22:47
Status: Temporary error, restart node

at one node and
Forced node shutdown completed. Occured during startphase 2. Caused by error 2308: 'Another node failed during system restart, please investigate error(s) on other node(s)(Restart error). Temporary error, restart node'.
at all other.

Each time we tried we got this error. Does someone know, what it mean ? Or, may be, there is a way to recover anything from ndbd .dat files of node fs partitions ?
Please, advice
