oracle 12c rac asm使用nfs注意的问题

centos 6/7版本下

1.两节点网卡名称必须一致

ip a检查

/etc/udev/rules.d/70-persistent-net.rules检查mac地址是否匹配/etc/sysconfig/network-scripts

[root@rac1 oraInventory]# cat /etc/udev/rules.d/70-persistent-net.rules 
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.

# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="46:29:87:a4:d8:a3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x1af4:0x1000 (virtio-pci)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="52:89:69:d5:c6:d1", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

2.nfs server配置

NFS Server配置

[root@onas ~]# vi /etc/exports
/u02    *(rw,sync,no_wdelay,insecure,no_root_squash)
[root@onas ~]# systemctl restart nfs
[root@onas ~]# showmount -e
Export list for onas:
/u02 *

注意/u02下目录需保持为空 

for i in  {1..5};do dd if=/dev/zero of=/u02/asmdisk$i bs=1M count=10000;done
chmod 660 /u02/asmdisk*

3.nfs client配置，rac节点：

RAC节点分别编辑/etc/fstab文件，加入以下内容:

[root@odb01 ~]# vi /etc/fstab
onas:/u02               /u02            nfs     rw,bg,hard,nointr,tcp,vers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0  0 0

 测试mount -a是否正常。

4.grid安装时选择：
