症状

12c GI 安装过程中,如果 ASM 磁盘是基于 NFS 的,执行 root.sh 会遇到以下错误:

# /u01/app/12.1.0/grid/root.sh
Performing root user operation for Oracle 12c

磁盘 /asm/disk1和/asm/disk2 是通过 NFS 挂载的,被磁盘组 DATA 使用。它们权限没有问题,经过dd命令测试,读写操作也都正常。

mount option on the cluster is like:
192.168.1.1:/disks/12c on /asm type nfs (rw,tcp,vers=3,rsize=32768,wsize=32768,bg,hard,nointr,actimeo=0,timeo=600,addr=192.168.1.1)
