oracle11.2.0.3.0 RAC aix7100-02-02-1316 crs-4124,crs-4000错误问题解决
原因：
在测试机上首次安装oracle11G RAC，安装完成后正常使用，过了一段时间后重启节点1测试是否可以自启动，解决节点1没有自启动，手工启动也无法启动
过程：
在节点一上运行：
# pwd
/u01/grid/bin
# ./crsctl start crs
CRS-4124: Oracle High Availability Services startup failed.
CRS-4000: Command Start failed, or completed with errors.
查看节点1日志
# pwd
/u01/grid/log/nodea/client
# cat crsctl_grid.log

查看节点1磁盘空间，发现确实没有空间了

怀疑是数据库一直报警导致日志增大将空间占满了，进入oracle数据库告警日志
$ pwd
/u01/base/diag/rdbms/test/test1/trace
$ du -sg /u01/base/diag/rdbms/test/test1/trace
-
/u01/base/diag/rdbms/test/test1/trace
删除所有告警日志，因为是测试库，所以不去查到底是什么原因导致数据库一直报警。节点2服务器磁盘空间没有占满。
重新使用root用户启动crs，提示crs已经启动，但是使用crs_stat没有查到进场，原因回来再查询吧
