# Automatic Storage Management library kernel driver.  It is generated

* 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。
