ACFS file system creation using Manual Method. Steps to create ACFS file system
Step 1: List the disks using the below command.
col name for a30;
SELECT NAME, VALUE, GROUP_NUMBER FROM v$asm_attribute where name like '%com%';
Step 2: Create the oracleasm disk using the below command.
#oracleasm create disk ACFS /dev/mapper/DISK014_ARCH_4T1
Step 4: Verify the header status of the path is provisioned using the below query.
col PATH for a50;
select path, group_number group_#, disk_number disk_#, mount_status,header_status, state, total_mb, free_mb from v$asm_disk order by group_number;
SQL> SELECT NAME,VALUE,GROUP_NUMBER FROM v$asm_attribute where name like '%com%';
CREATE DISKGROUP FRA EXTERNAL REDUNDANCY DISK ‘/dev/oracleasm/disks/ARCH03’ NAME FRA_01 ATTRIBUTE compatible.asm’ = ‘12.2.0.1.0’, ‘compatible.rdbms’=’12.2.0.1.0’ ,‘compatible.advm’ = 12.2.0.1.0’;
Step 7: Verify the diskgroup has been created using the below query.
SQL> SELECT name, free_mb, total_mb, ((total_mb-free_mb)/total_mb)*100 as "USED %", free_mb/total_mb*100 "FREE%" from v$asm_diskgroup order by 1;
NAME FREE_MB TOTAL_MB USED % FREE%

Step 8: Mount the diskgroup using the below command.
ALTER DISKGROUP FRA MOUNT;
ASMCMD [+] > volcreate -G DATA -s 10G --width 64K --column 8 oraacfs
Step 9: Create the volume using the below command and verify the created volume information using the below command.
ASMCMD> volinfo -G ORAACFSDG volume1
Diskgroup Name: ORAACFSDG
Volume Name: oraacfs
Volume Device: /dev/asm/volume1-453
State: ENABLED

Resize Unit (MB): 64
Redundancy: UNPROT
Stripe Columns: 8

Mountpath:
Step 10: Create the acfs file system
mkfs -t oraacfs1 -f /dev/asm/volume1-453
Step 11: Create a directory from the root user and provide the required privilege (in both nodes)
mkdir -p /acfsarch
chown oracle:oinstall /acfsarch
Step 12: Register the file system using the below command from the root user and verify the file system on both the nodes.
/sbin/acfsutil registry -a /dev/asm/acfsarch-243 /acfsarch -u oracle
df -h /acfsarch
