現象如下：
node1的crs,evm服務不能啟動,node2的crs服務是正常的。
inode1:oracle:orcl1:/home/Oracle> exit
inode1:root::/> /etc/init.crs start
Startup will be queued to init within 30 seconds.
inode1:oracle:orcl1:/home/Oracle> crsctl check crs
CSS appears healthy
Cannot communicate with CRS
Cannot communicate with EVM
inode1:oracle:orcl1:/home/Oracle> crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.
在crsd.log中發現一直報下面的錯誤，基本上是每1s報一次,
inode1:oracle:orcl1:/db/Oracle/product/10.2.0/crs/log/inode1/crsd> tail -f crsd.log

分析：
由於之前有一個磁盤出現問題，對datavg卷組進行了exportvg,importvg操作，
inode1:oracle:orcl1:/home/Oracle> lsvg -p datavg
datavg:
PV_NAME PV STATE TOTAL PPs FREE PPS FREE DISTRIBUTION
hdisk2 active 799 759 160..120..159..160..160
hdisk3 missing 799 799 160..160..159..160..160
inode1:root:>exportvg datavg
inode1:root:>importvg -V60 -y datavg hdisk2
這樣操作後再啟動crs就出現上面的現象
解決：
刪除node1機器上的/etc/oracle/scls_scr/rac1/Oracle/CSSfatal 文件
如果不刪這個文件，運行root.sh 腳本時會報錯。
然後重新運行下$ORA_CRS_HOME/root.sh腳本
