Shared Storage¶

For configurations with 2 or more Applications Nodes, Shared Storage is required between the app nodes. Local Storage File Shares will need to be copied to a shared file system so all assets are available on all App nodes.

Assets¶

White label images
Uploaded virtual images
Deploy uploads
Ansible Plays
Terraform
Morpheus backups

Tip

Backups, deployments and virtual image storage locations can be overridden within the Morpheus-ui. You can find more information on storage here: Storage

To copy the morpheus-ui directory to the shared storage follow the below steps:

SSH into the Appliance
sudo su (or login as root)
cd into /var/opt/morpheus/
Backup morpheus-ui directory by running the command below. This will create a new directory in /var/opt/morpheus/ called morpheus-ui-bkp and copy the contents of morpheus-ui into the new directory
```
cp -r morpheus-ui morpheus-ui-bkp
```
Move morpheus-ui to your shared storage. Example below:
```
mv morpheus-ui /nfs/appliance-files/
```
Mount your shared storage volume to /var/opt/morpheus/morpheus-ui. How you mount it is dependent on what kind of storage it is. If you mount the volume after the package install, but before the reconfigure, then you don’t need to copy anything to a backup.
SSH into the second Appliance and then Backup morpheus-ui directory by running
```
cp -r morpheus-ui morpheus-ui-bkp
```

Tip

When adding additional nodes you will only need to run step 6 and 7

Important

NFS mounts require sync option when using Ansible integration with Morpheus Agent command bus execution enabled.

Important

On each application node, the morpheus-app and morpheus-local user and group uid/gid should be consistent. If the uid and/or gid are different between nodes, when the permissions are applied during a reconfigure, the permissions can be incorrect for other nodes. The uid and gid for the users can be seen by executing: sudo cat /etc/passwd and sudo cat /etc/groups
