Oracle ODA X9 (19c): Create a Backup ACFS volume

Starting with ODA 19.6, the DB homes are created on ACFS file systems, and we can also create an ACFS volume for RMAN backups and for DATA PUMP exports, and in this article, we will create a 4 TB volume for backups

Step 01: Check the free Space with ODA commands:

[root@wadhah-odax9-node01 ~]# odacli list-dgstorages

Note: We have 16 TB free space on DATA diskgroup

Step 02: CREATE an RMAN Volume (ACFS) from the DATA DiskGroup:

[grid@wadhah-odax9-node01 ~]$ asmcmd volcreate -G DATA -s 4096G RMANBKP
[grid@wadhah-odax9-node01 ~]$ asmcmd volinfo -G DATA RMANBKP

Diskgroup Name: DATA

         Volume Name: RMANBKP
         Volume Device: /dev/asm/rmanbkp-254
         State: ENABLED
         Size (MB): 4194304
         Resize Unit (MB): 64
         Redundancy: MIRROR
         Stripe Columns: 8
         Stripe Width (K): 1024
         Usage:
         Mountpath:

Step 03: Make the ACFS file system

Using the command mkfs, we format the ASM Volume

[root@wadhah-odax9-node01 ~]# mkfs -t acfs /dev/asm/rmanbkp-254
mkfs.acfs: version                   = 19.0.0.0.0
mkfs.acfs: on-disk version           = 46.0
mkfs.acfs: volume                    = /dev/asm/rmanbkp-254
mkfs.acfs: volume size               = 4398046511104  (   4.00 TB )
mkfs.acfs: Format complete.
[root@wadhah-odax9-node01 ~]#

Step 04: Set up the ACFS volume with the cluster:

Create cluster file system

[root@wadhah-odax9-node01 ~]# export PATH=$PATH:/u01/app/19.25.0.0/grid/bin
[root@wadhah-odax9-node01 ~]# srvctl add filesystem -device /dev/asm/rmanbkp-254 -path /backupRMAN -user oracle -fstype ACFS -autostart ALWAYS
[root@wadhah-odax9-node01 ~]# srvctl start filesystem -device /dev/asm/rmanbkp-254
[root@wadhah-odax9-node01 ~]# srvctl status filesystem
