Create and Monitor ACFS using cmd

1. Configure a initialization script to load the ACFS modules at startup. 

[root@node1 ~]# vi /etc/init.d/acfsload
#!/bin/sh

# chkconfig: 2345 30 21
# description: Load Oracle ACFS drivers at system boot
/data01/app/11.2.0/grid_1/bin/acfsload start -s


[root@node1 ~]# chmod u+x /etc/init.d/acfsload

[root@node1 ~]# chkconfig --list acfsload
acfsload       0:off 1:off 2:on 3:on 4:on 5:on 6:off

[root@node1 ~]# /data01/app/11.2.0/grid_1/bin/acfsload start -s

[root@node1 ~]# lsmod | grep -i oracle
oracleacfs           1976568  0
oracleadvm            243152  0
oracleoks             426742  2 oracleacfs,oracleadvm
oracleasm              53865  1

2. Create diskgroups for acfs volumes :

SQL> CREATE DISKGROUP ACFS_DG1 EXTERNAL REDUNDANCY DISK 'ORCL:DISK3'
ATTRIBUTE  'compatible.asm' = '11.2.0.2.0', 'compatible.rdbms' = '11.2.0.2.0', 'compatible.advm' = '11.2.0.2.0' ;

Diskgroup created.

SQL> CREATE DISKGROUP ACFS_DG2 EXTERNAL REDUNDANCY DISK 'ORCL:DISK1'
   ATTRIBUTE  'compatible.asm' = '11.2.0.2.0', 'compatible.rdbms' = '11.2.0.2.0', 'compatible.advm' = '11.2.0.2.0' ;

Diskgroup created.

SQL> select name,STATE  , TYPE  ,   TOTAL_MB , FREE_MB from v$asm_diskgroup where name in ('ACFS_DG1' ,'ACFS_DG2' );

NAME     STATE     TYPE    TOTAL_MB FREE_MB
-------------------- --------------- -------------------- ---------- ----------
ACFS_DG1     MOUNTED     EXTERN 5114   5064
ACFS_DG2     MOUNTED     EXTERN 3067   3017


SQL> select name,compatibility, database_compatibility from v$asm_diskgroup where name in ('ACFS_DG1' ,'ACFS_DG2' );;

NAME       COMPATIBILITY DATABASE_COMPATIBILITY
------------ -------------------- -------------------------------------
ACFS_DG1  11.2.0.2.0 11.2.0.2.0
ACFS_DG2  11.2.0.2.0 11.2.0.2.0

3. Create/Add volumes to the diskgroups :

SQL> alter diskgroup ACFS_DG1 add volume 'ACFS_vol1' size 5000M;

Diskgroup altered.

SQL> alter diskgroup ACFS_DG2 add volume 'ACFS_vol2' size 3000M;

Diskgroup altered.

4. Enable the Volumes 

SQL> alter diskgroup ACFS_DG2 enable volume 'ACFS_vol2';

Diskgroup altered.

SQL> alter diskgroup ACFS_DG1 enable volume 'ACFS_vol1' ;

Diskgroup altered.


SQL> SELECT dg.name AS diskgroup, v.volume_name, v.volume_device, v.mountpath,v.state FROM V$ASM_DISKGROUP dg, V$ASM_VOLUME v WHERE dg.group_number = v.group_number;
 

DISKGROUP   VOLUME_NAME     VOLUME_DEVICE      MOUNTPATH  STATE
------------------------------ --------------- ------------------------------ ---------- ------------------------
ACFS_DG1     ACFS_VOL1         /dev/asm/acfs_vol1-454             ENABLED
ACFS_DG2     ACFS_VOL2         /dev/asm/acfs_vol2-444             ENABLED

5. Register mount point

[root@node1 ~]# mkdir -p /acfs_mount/acfs_vol1_DG1

[root@node1 ~]# acfsutil registry -a -f /dev/asm/acfs_vol1-454 /acfs_mount/acfs_vol1_DG1
acfsutil registry: mount point /acfs_mount/acfs_vol1_DG1 successfully added to Oracle Registry

[root@node1 ~]# mkdir -p /acfs_mount/acfs_vol2_DG2
[root@node1 ~]# acfsutil registry -a -f /dev/asm/acfs_vol2-444 /acfs_mount/acfs_vol2_DG2
acfsutil registry: mount point /acfs_mount/acfs_vol2_DG2 successfully added to Oracle Registry

[root@node1 ~]# df -kh
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_node1-lv_root
                       28G   16G   11G  61% /

[root@node1 ~]#

6. Now mount the acfs_mounts created above :

[root@node1 ~]# mkfs.acfs -f /dev/asm/acfs_vol1-454
mkfs.acfs: version                   = 11.2.0.4.0
mkfs.acfs: on-disk version           = 39.0

mkfs.acfs: volume size               = 5268045824
mkfs.acfs: Format complete.

[root@node1 ~]# mkfs.acfs -f  /dev/asm/acfs_vol2-444
