====== [DOC] ACFS on GRID ======



1) Please create the mount points on all the nodes (as root user):
<code bash>
[root@dbaasm ~]#  mkdir /goldengate
</code>
2) Connect to the ASM instance & create the ACFS diskgroup (from the +ASM1 instance):
<code sql>
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';
</code>
Diskgroup created.


3) Create the ACFS volume (from the +ASM1 instance):
<code sql>
SQL> ALTER DISKGROUP ACFSTEST ADD VOLUME ACFSTESTVOL SIZE 7G;

Diskgroup altered.
</code>
4) Verify the volume was created and obtain the new volume name:
<code bash>
[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:
</code>

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

</code>

6) Register the ACFS filesystem & new volume with the CRS as root user:
<code bash>
[root@dbaasm ~]#  <GI Oracle Home>/bin/srvctl add filesystem -d /dev/asm/acfstestvol-76 -g 'ACFSTEST' -v ACFSTESTVOL -m /goldengate -u oracle
</code>

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

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

8) Set the desired new ownership and permissions as root user:
<code bash>
[root@dbaasm ~]# chown oracle:oinstall /goldengate

[root@dbaasm ~]# chmod 775 /goldengate
</code>

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


Node #1
<code bash>
[root@asmgrid1 ~]# df -k /goldengate
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/asm/acfstestvol-76  35651584   4590104  31061480  13% /goldengate
</code>
Node #2
<code bash>
[root@asmgrid2 ~]# df -k /goldengate
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/asm/acfstestvol-76  35651584   4590104  31061480  13% /goldengate
</code>
10) Verify the ACFS CRS resource is present in the CRS:

<code bash>

[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
 </code>
