OMV Setup

Open Media Vault Setup:

1. Access OMV by typing in the IP address of the Pi into your web browser. OMV's web dashboard will show up. The default login:

   1. User: admin

   2. password: openmediavault

2. OMV Setup:

   1. Change the Password: User Settings Icon in the top right of the web UI

   2. Dashboard Setup: User Settings -> Dashboard

   3.  Setting up RAID:

      1. Install RAID plugin: System -> plugins -> search for "md" -> Select openmediavault-md -> Install -> You should see Multiple Devices appear under Storage

      2. Wipe Disks: Storage -> Disks -> Left Click each disk -> Wipe (eraser button) -> Confirm -> Quick

      3. Setup RAID: Storage -> Multiple Devices -> Create (+ button) -> Level: RAID 5 -> Select Devices: all your drives you want in RAID -> Save

         1. RAID 5 only works with the same storage amount HDDs

      4. Setup File System: Create and Mount a File System (+ button) -> EXT4 -> Select the RAID device you just made -> Save

   4. Set up a Shared Folder:

      1. Storage -> Shared Folders -> Create (+ button) -> Name the Shared folder -> Change Permissions -> Save

   5. Enable SMB/CIFS:

      1. Enable SMB/CIFS service: Services -> Settings -> Click "Enabled" Check mark box -> Save

      2. Shares -> Select the folder you want to share -> Change Public Setting if you want to (default No) -> Save

   6. Create a User: 

      1. User Management -> Users -> Create (+ button) -> Name the user -> create the password -> Save

      2. User Management -> Users -> Select a User -> Shared folder permissions (Folder with a key button) -> Give permissions to user

NOTE: When setting up Users, you will notice a user with the hostname of the Pi (Mine was pi-5-nas). This user is a part of many groups and is used as an SSH access point to OMV when you are initialy setting up OMV. DO NOT DELETE THIS USER. If you delete this user, you lose SSH permissions to the RPi and OMV. I found that you can setup a user with the same name (if accidentally deleted) in OMV, but I don't know if not having this default user messes anything else up in OMV. 

1. Go to the OMV Web GUI -> Type in your IP address into your browser

2. login with admin credentials

3. User -> Create new user -> Name: pi-5-nas and create password -> groups -> ssh, users, and sudo -> Save

4. SSH into the Pi again through cmd: ssh pi-5-nas@192.168.1.XXX (Syntax: ssh username@pi_ip_address)

5. If your username and pass worked, you will see the error: Could not chdir to home directory /home/pi-5-nas: Permission denied

6. In SSH, run the commands : 

   1. sudo mkdir -p /home/pi-5-nas

   2. sudo chown -R pi-5-nas:pi-5-nas /home/pi-5-nas

   3. sudo chmod 755 /home/pi-5-nas

   4. exit

7. SSH into the Pi again: ssh pi-5-nas@192.168.1.XXX

8. Check home directory: getent passwd pi-5-nas. You should see something like: /home/pi-5-nas

9. You should be able to SSH into OMV again now. 

At this point, I just decided to reflash the SD Card and re-setup OMV

Important Things to Note About Shared Folders in OMV:

1. When you are accessing OMV shared folders through IP address/hostname in file explorer on a PC, you can login into multiple shared folders with different credentials. EX: I can login into "media" folder with user "Eddie" and "photos" folder with user "Bob" as long as I know both credentials.
