1 problem description

Two-node Oracle 10g RAC database, CRS on node db1 failed to start, but CRS on node db2 started successfully.

Problem: after entering the crsctl start crs command on the node db1, the crs process is not seen on the operating system.

2 treatment process

Check the CRS log $ORA_CRS_HOME/log on node db1 and find no recent CRS process log content. The reason for no log is that the crs process is not started at all.

1. Check the CRS installation configuration file to get the names of OCR disk and voice disk

More $ORA_CRS_HOME/install/rootconfig...

CRS_OCR_LOCATIONS=/dev/rhdisk3,dev/rhdisk4...

CRS_VOTING_DISKS=/dev/rhdisk5,dev/rhdisk7,/dev/rhdisk8...

two。 Check the owner and read and write permissions of OCR disk voice disk

Ls-l / dev/rhdisk*

The check results show that the owner and read and write permissions of OCR disk voice disk are correct: OCR disk owner root:oinstall, Vote disk owner oracle:dba, both read and write permissions are 660

3. Check the OCR disk

Ocrcheck

The check results show that the OCR disk is normal: Cluster registry integrity check succeeded

4. Check the voice disk.

Crsctl query css votedisk

5 check the properties and permissions of the $ORA_CRS_HOME directory

Ls-l $ORA_CRS_HOME

The properties and permissions of the $ORA_CRS_HOME directory are normal

6 crsctl check boot

Ping db1-priv failed

Confirm that an exception in the db1-priv network caused the CRS to fail to start

Problem solving: just get through the private network.

Crsctl stop crs

Crsctl start crs

Started successfully
