Below are the Manual Steps to Setup ACFS file system in ODA box with GI version 11.2

Terminology
———–
DATA – is the diskgroup from which we are taking space (-volumeDiskGroup parameter)
1024 GB – is the space that we are allocating (-volumeSizeGB parameter )
acfsbkpvol – is the ACFS volume name (-volumeName parameter)
/backupfs – is the file system that will be mounted on both the ODA nodes
GI_GOME = /u01/app/11.2.0.4/grid
+ASM = instance name

Steps

——

 1. Open a terminal window and log in as grid user (to the node 1)
 #su - grid
2. Setup the right environment variables to connect ASM instance
 $export ORACLE_HOME=/u01/app/11.2.0.4/grid
 $export ORACLE_SID=+ASM1
3. Create your ACFS volume executing the following command:
 /u01/app/11.2.0/grid/bin/asmca -silent -createVolume -volumeName RECO -volumeDiskGroup <volume_disk_group> -volumeSizeGB <volume_size> -sysAsmPassword <sysasmpassword>
 for example:-
 /u01/app/11.2.0.4/grid/bin/asmca -silent -createVolume -volumeName acfsbkpvol -volumeDiskGroup DATA -volumeSizeGB 1024 -sysAsmPassword <sysasmpassword>
4. Verify your volume creation
 /u01/app/11.2.0.4/grid/bin/asmcmd volinfo -G DATA acfsbkpvol | grep -oE '/dev/asm/.*'
 Volume Device: /dev/asm/<To_be_obtained>

for example:- Volume Device: /dev/asm/acfsbkpvol-107
5. Create the ACFS filesystem

/u01/app/11.2.0/grid/bin/asmca -silent -createACFS -acfsVolumeDevice <volume_device>

for example:-
 /u01/app/11.2.0.4/grid/bin/asmca -silent -createACFS -acfsbkpvolumeDevice <volume_device>
 <volume_device> is the one which is obtained in Step 4 output.
6. Create the mount point
 Open a terminal window and log in as root (on both nodes)
 mkdir /backupfs
 chown grid:asmdba /backupfs
7. Add the new ACFS as cluster resource
 Execute on node 1 as root user the following:

/u01/app/11.2.0/grid/bin/srvctl add filesystem -d <volume_device> -g RECO -v <volumename> -m <mount_point> -u grid

for example:-
 /u01/app/11.2.0.4/grid/bin/srvctl add filesystem -d <volume_device> -g DATA -v acfsbkpvol -m /backupfs -u grid
 <volume_device> is the one which is obtained in Step 4 output.
8. Mount the filesystem
 /u01/app/11.2.0/grid/bin/srvctl start filesystem -d <volume_device>

/u01/app/11.2.0.4/grid/bin/srvctl start filesystem -d <volume_device>
 <volume_device> is the one which is obtained in Step 4 output.
9. Display all ACFS registered file systems issuing the following command
 #acfsutil info fs
