Creating a Persistent Volume Directory

6.3 Creating a Persistent Volume Directory

As referenced in System Requirements for OUDSM on Kubernetes the nodes in the Kubernetes cluster must have access to a persistent volume such as a Network File System (NFS) mount or a shared file system.

In the examples below an NFS volume is mounted on all nodes in the Kubernetes cluster, and is accessible via the directory /nfs_volumes/oudsmpv.

Perform the following steps:

On the administrative host, run the following command to create an oudsm_user_projects directory:

cd <persistent_volume>
mkdir oudsm_user_projects
sudo chown -R 1000:0 oudsm_user_projects

For example:

cd /nfs_volumes/oudsmpv
mkdir oudsm_user_projects   
sudo chown -R 1000:0 oudsm_user_projects

On the administrative host run the following to ensure it is possible to read and write to the persistent volume:

Note:
The following assumes the user creating the file has userid 1000 or is part of group 0.
```
cd <persistent_volume>/oudsm_user_projects
touch fileadmin.txt
ls fileadmin.txt
```
For example:
```
cd /nfs_volumes/oudsmpv/oudsm_user_projects
touch fileadmin.txt
ls fileadmin.txt
```
