All about Oracle ACFS
1) Create the new ACFS diskgroup:
[grid@asmlnx2 ~]$ sqlplus "/as sysasm"
SQL*Plus: Release 11.2.0.3.0 Production on Fri Apr 6 17:38:38 2012
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
With the Automatic Storage Management option
SQL> CREATE DISKGROUP ACFSDG EXTERNAL REDUNDANCY DISK
'ORCL:ASMDISKNEW10' SIZE 14653 M
ATTRIBUTE 'compatible.rdbms' = '11.2', 'compatible.asm' = '11.2', 'compatible.advm' = '11.2'; 2 3
Diskgroup created.
SQL> exit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production

[grid@asmlnx2 ~]$
2) Create the ADVM volume in the new diskgroup:
[grid@asmlnx2 ~]$ sqlplus "/as sysasm"
SQL*Plus: Release 11.2.0.3.0 Production on Fri Apr 6 17:41:09 2012

With the Automatic Storage Management option
SQL> ALTER DISKGROUP ACFSDG ADD VOLUME EBERNALVOL SIZE 14G;
Diskgroup altered.

3) Create the mount point as root OS user:
[root@asmlnx2 ~]# mkdir /u03acfs
[root@asmlnx2 ~]# chown grid:oinstall /u03acfs
[root@asmlnx2 ~]# ls -ld /u03acfs
drwxr-xr-x 2 grid oinstall 4096 Apr 6 17:45 /u03acfs
4) As grid user create the ACFS filesystem:
[grid@asmlnx2 ~]$ id
uid=1100(grid) gid=501(oinstall) groups=500(dba),501(oinstall),1100(asmadmin),1300(asmdba),1301(asmoper)
[grid@asmlnx2 ~]$ /sbin/mkfs -t acfs -b 4k /dev/asm/ebernalvol-168
mkfs.acfs: version = 11.2.0.3.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/ebernalvol-168
mkfs.acfs: volume size = 15032385536
mkfs.acfs: Format complete.
[grid@asmlnx2 ~]$
5) As grid user register the ACFS filesystem & ADVM volume:
[grid@asmlnx2 ~]$ /sbin/acfsutil registry -f -a /dev/asm/ebernalvol-168 /u03acfs
acfsutil registry: ACFS-05062: cannot query CRS resource
[grid@asmlnx2 ~]$
SQL> /* ASMCMD */alter diskgroup oggacfs drop volume 'oggvol1'
2013-05-16 14:29:28.669000 +08:00
SUCCESS: /* ASMCMD */alter diskgroup oggacfs drop volume 'oggvol1'
SQL> alter diskgroup oggacfs resize volume oggvol1 size 90G
ORA-15032: not all alterations performed
ORA-15476: ACFS volumes must be resized with the 'acfsutil size' operating system command.
