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

Hello Quanwen,
what kind of disks are these? There are known problems for some disk types, e.g. please check MOS ID #2214152.1 and your problem description sounds like such an issue.

> Hello everybody 😊, I'm using ASMLib (not UDEV) to create ASM disks on RAC 19c/12c but why it always doesn't startup after restarting my Linux 7 server? 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!!!
