-### Oracle RAC Storage container for Docker Host
-
-To use NFS volumes in containers, you must install NFS server RPMs on the Podman host:
-
-```bash
-yum install -y nfs-utils
-```
-#### Prerequisites for an Oracle RAC Storage Container for Docker Host
-
-Create a placeholder for NFS storage, and ensure that it is empty:
-```bash
-export ORACLE_DBNAME=ORCLCDB
-mkdir -p /scratch/docker_volumes/asm_vol/$ORACLE_DBNAME
-rm -rf /scratch/docker_volumes/asm_vol/$ORACLE_DBNAME/asm_disk0*
-```
-
-#### Deploying Oracle RAC Storage Container for Docker Host
-
-If you are building an Oracle RAC storage container on Docker host machines, then run the following commands:
-
-```bash
-export ORACLE_DBNAME=ORCLCDB
-docker run -d -t \
---hostname racnode-storage \
---dns-search=example.info  \
---cap-add SYS_ADMIN \
---cap-add AUDIT_WRITE \
---volume /scratch/docker_volumes/asm_vol/$ORACLE_DBNAME:/oradata --init \
---network=rac_pub1_nw --ip=10.0.20.80 \
---tmpfs=/run  \
---volume /sys/fs/cgroup:/sys/fs/cgroup:ro \
---name racnode-storage \
-oracle/rac-storage-server:ol7
-```
-
-To check the Oracle RAC storage container and services creation logs, you can run a `tail` command on the Docker logs. It should take 10 minutes to create the racnode-storage container service.
-
-```bash
-docker logs -f racnode-storage
-```
-
 **IMPORTANT:** During the container startup, five files with the name  `asm_disk0[1-5].img` will be created under `/oradata`. If the files are already present, then they will not be recreated. These files can be used for ASM storage in Oracle RAC containers.
 
 **NOTE**: Place the directory in a container that has at least 60 GB. In the preceding example, we are using `/scratch/stage/rac-storage/$ORACLE_DBNAME`. Change these values according to your environment. Inside the container, the directory will be `/oradata`. Do not change this value.
 
 In the following example, we use **192.168.17.0/24** as the subnet for the NFS server. You can change the subnet values according to your environment.
 
-You should see following in the Docker logs output:

-
 **IMPORTANT:** The NFS volume must be `/oradata`, which you will export to Oracle RAC containers for ASM storage. It will take approximately 10 minutes to set up the NFS server.
