查看oracleasm信息:

# This is a configuration file for automatic loading of the Oracle
# Automatic Storage Management library kernel driver.  It is generated
# By running /etc/init.d/oracleasm configure.  Please use that method
# to modify this file
#

# ORACLEASM_ENABELED: 'true' means to load the driver on boot.
ORACLEASM_ENABLED=true

# ORACLEASM_UID: Default user owning the /dev/oracleasm mount point.
ORACLEASM_UID=grid

# ORACLEASM_GID: Default group owning the /dev/oracleasm mount point.
ORACLEASM_GID=asmadmin

# ORACLEASM_SCANBOOT: 'true' means scan for ASM disks on boot.
ORACLEASM_SCANBOOT=true

# ORACLEASM_SCANORDER: Matching patterns to order disk scanning
ORACLEASM_SCANORDER="multipath sd"

# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
ORACLEASM_SCANEXCLUDE="sdf sdg sdh sdi"

* fdisk -l 的信息与oracleasm的磁盘信息不符

fdisk -l的磁盘为sdb sdc sdd sde

将ORACLEASM_SCANEXCLUDE="sdf sdg sdh sdi" -> ORACLEASM_SCANEXCLUDE="sdb sdc sdd sde"


重启crs,OK

检查状态:

$ srvctl status asm

$ srvctl status instance -d devdb -i devdb1

$ srvctl status database -d devdb

节点linuxdb1连接数据库一切正常。
