Question

RAC: The node rebooted after a problem with storage.

Answer 1

The ocssd.log file shows that the node rebooted because it cannot access a majority of voting disks

Answer 2

Cause: CRS must be able to access a majority of voting disks. If CRS has a problem with a majority of voting disks, CRS cannot ensure the integrity of the cluster, so CRS reboots the node.

 

Solution: Fix the problem with the voting disk. Make sure that voting disks are available and accessible by user oracle or grid or any user who owns CRS or GI HOME. If the voting disk is not in ASM, use "dd if= of=/dev/null bs=1024 count=10240" to test the accessibility
