1、数据节点的IP地址和其它的客户端主机冲突导致的错误。
管理节点报告：
ndb_mgm> Node 4: 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'.

2、我进行在线恢复的时候出现的。
[root@localhost data]# /usr/local/mysql/bin/ndb_restore -n5 -b1 -r -m --backup_path=/usr/local/mysql/data/BACKUP/BACKUP-1/
Nodeid = 5
Backup Id = 1
backup path = /usr/local/mysql/data/BACKUP/BACKUP-1/
Ndb version in backup files: Version 5.1.22
Configuration error: Error : Could not alloc node id at 192.168.0.231 port 1186: No free node id found for mysqld(API).
Failed to initialize consumers
NDBT_ProgramExit: 1 - Failed
原因是我的管理节点配置中的SQL节点部分没有加空的[MYSQLD]部分。
所以我加了和SQL节点数目一致的[MYSQLD]就好了。
多谢CU的showsa兄弟。
3、早上来的时候发现数据节点DOWN掉了
Time: Sunday 16 December 2007 - 09:01:40
Status: Temporary error, restart node
Message: Internal program error (failed ndbrequire) (Internal error, programming error or missing error message, please report a bug)

结果办法：
在管理节点的配置文件中添加：
[ndbd default]
MaxNoOfOrderedIndexes=512
默认值是128
