3）格式化文件系统为acfs
eg：
[root@oracle-one ~]# /sbin/mkfs -t acfs -n acfsvol0 /dev/asm/acfsvol0-142 mkfs.acfs: version = 11.2.0.4.0 mkfs.acfs: on-disk version = 39.0 mkfs.acfs: volume = /dev/asm/acfsvol0-142 mkfs.acfs: volume size = 536870912 mkfs.acfs: Format complete. [root@oracle-one ~]# /sbin/mkfs -t acfs -n acfsvol1 /dev/asm/acfsvol1-142 mkfs.acfs: version = 11.2.0.4.0 mkfs.acfs: on-disk version = 39.0 mkfs.acfs: volume = /dev/asm/acfsvol1-142 mkfs.acfs: volume size = 536870912 mkfs.acfs: Format complete. [root@oracle-one ~]#
4)注册acfs文件系统信息；
[root@oracle-one ~]# mkdir -p /ginf/grid/acfs acfssystem/ acfsvolume/ [root@oracle-one ~]# mkdir -p /ginf/grid/acfssystem/acfsvol0 You have new mail in /var/spool/mail/root [root@oracle-one ~]# mkdir -p /ginf/grid/acfssystem/acfsvol1 [root@oracle-one ~]# /sbin/acfsutil registry -a -f /dev/asm/acfsvol0-142 /ginf/grid/acfssystem/acfsvol0 acfsutil registry: mount point /ginf/grid/acfssystem/acfsvol0 successfully added to Oracle Registry [root@oracle-one ~]# /sbin/acfsutil registry -a -f /dev/asm/acfsvol1-142 /ginf/grid/acfssystem/acfsvol1 acfsutil registry: mount point /ginf/grid/acfssystem/acfsvol1 successfully added to Oracle Registry [root@oracle-one ~]#
5）挂在acfs文件信息：
[root@oracle-one ~]# mount.acfs -o all
[root@oracle-one ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_oracleone-lv_root
5.0G 3.9G 876M 82% /
tmpfs 1.0G 83M 942M 9% /dev/shm
/dev/sda1 485M 55M 405M 12% /boot
/dev/mapper/vg_oracleone-LogVol02
5.0G 2.2G 2.6G 46% /home
/dev/mapper/vg_oracleone-LogVol03
13G 7.0G 4.8G 60% /opt
/dev/sdf1 5.0G 139M 4.6G 3% /tmp
/dev/sdg1 16G 4.3G 11G 29% /ginf
/dev/asm/acfsvol0-142
512M 40M 473M 8% /ginf/grid/acfssystem/acfsvol0
/dev/asm/acfsvol1-142
512M 40M 473M 8% /ginf/grid/acfssystem/acfsvol1
[root@oracle-one ~]#
至此acfs文件系统创建完成。
二）动态扩展acfs文件系统。
acfs可以支持卷组的动态扩展类似aix的chfs -a size=xx directory，只要磁盘组有足够的空间就可进行动态扩展。
eg：
-bash-4.1$ sqlplus / as sysdba
