Re: Why ASMLib doesn't restart automatically on Oracle RAC 19c/12c after restarting Linux 7 server?

 Quanwen,      

Pls check the order of startup of services.      

It is possible that in Linux 7, the starting   

order could have changed compared to   

Linux 6.      

Regards,   

Rajeev

Next I checked the CRS log file - reported voting files never found in 15 seconds so I continued to look at "/dev/oracleasm", oh my god, never existed oracleasm on /dev!!!
