1) Please create the mount points on all the nodes (as root user):

[root@dbaasm ~]#  mkdir /goldengate

2) Connect to the ASM instance & create the ACFS diskgroup (from the +ASM1 instance):

SQL> CREATE DISKGROUP ACFSTEST EXTERNAL REDUNDANCY
DISK 'ORCL:ASMDISK18' SIZE 4157 M
DISK 'ORCL:ASMDISK19' SIZE 4157 M
ATTRIBUTE 'compatible.asm' = '11.2', 'compatible.advm' = '11.2';

Diskgroup created.

3) Create the ACFS volume (from the +ASM1 instance):

SQL> ALTER DISKGROUP ACFSTEST ADD VOLUME ACFSTESTVOL SIZE 7G;
 
Diskgroup altered.

4) Verify the volume was created and obtain the new volume name:

[grid@dbaasm grid]$ asmcmd
ASMCMD> volinfo -a
 
 
Diskgroup Name: ACFSTEST
 
Volume Name: ACFSTESTVOL
Volume Device: /dev/asm/acfstestvol-76
State: ENABLED
Size (MB): 7168
Resize Unit (MB): 256
Redundancy: UNPROT
Stripe Columns: 4
Stripe Width (K): 128
Usage:
Mountpath:

5) From the first node, please create the ACFS filesystem on the new volume ( e.g. “/dev/asm/acfstestvol-76”) as “grid” user:

[root@dbaasm ~]# /sbin/mkfs -t acfs -b 4k /dev/asm/acfstestvol-76
mkfs.acfs: version = 11.2.0.1.0.0
mkfs.acfs: on-disk version = 39.0
mkfs.acfs: volume = /dev/asm/acfstestvol-76
mkfs.acfs: volume size = 7516192768
mkfs.acfs: Format complete

6) Register the ACFS filesystem & new volume with the CRS as root user:

[root@dbaasm ~]#  <GI Oracle Home>/bin/srvctl add filesystem -d /dev/asm/acfstestvol-76 -g 'ACFSTEST' -v ACFSTESTVOL -m /goldengate -u oracle

7) Start the new ACFS CRS resource (as root user):

[root@dbaasm ~]# <GI Oracle Home>/bin/srvctl start filesystem -d /dev/asm/acfstestvol-76

8) Set the desired new ownership and permissions as root user:

[root@dbaasm ~]# chown oracle:oinstall /goldengate
 
[root@dbaasm ~]# chmod 775 /goldengate

9) Verify the new ACFS CRS managed filesystem is mounted on both nodes:

Node #1

[root@asmgrid1 ~]# df -k /goldengate
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/asm/acfstestvol-76  35651584   4590104  31061480  13% /goldengate

Node #2

[root@asmgrid2 ~]# df -k /goldengate
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/asm/acfstestvol-76  35651584   4590104  31061480  13% /goldengate

10) Verify the ACFS CRS resource is present in the CRS:

[root@asmgrid1 ~]# crsctl stat res -w  "TYPE = ora.acfs.type"
 
NAME=ora.acfstest.acfstestvol.acfs
TYPE=ora.acfs.type
TARGET=ONLINE
STATE=ONLINE on asmgrid1, asmgrid2
