Create Storage Volume
1. Login (you can probably access the server at http://openmediavault.local/, the default user name is admin, and default password is openmediavault)
2. You may need to create a partition on the flash drive first: If so go to Storage > Disks and select the drive, then click the wipe button, Confirm checkbox, Yes, and Quick to create a partition (you may even need to repeat if you get connection lost error)
3. Go to Storage > File Systems
4. Click + icon and then selec the BTRFS option
5. In the Profile drop down select single
6. In the Devices * drop down select the drive you want to use for storage
7. Click the Save button
8. In the File system * drop down select the formatted volume
9. Select Save again
10. Select the check mark icon to apply the changes when you see the "Pending configuration changes" message, select Yes to really apply changes
Create a Shared Folder
1. Go to Storage > Shared Folders
2. Click the + icon to create a shared folder
3. In the Name * box enter demo
4. In the File system * drop down select the filesystem
5. In the Permissions drop down select Everyone: read/write
6. Click the Save button
7. Select the check mark icon to apply the changes when you see the "Pending configuration changes" message, select Yes to really apply changes
Turn on services
1. Go to Services > NFS > Shares
2. Click the + icon to create a share
3. Under Shared folder * select the demo folder you created prior
4. In the Client * field enter the IP of the machine you would like to permit connections from, example: 192.168.10.0/24 (if your computer had an ip of 192.168.1.123 then this would be 192.168.1.0/24)
5. Under Permissions select Read/Write
6. For the tag field enter NFS
7. Click the Save button
8. Select the check mark icon to apply the changes when you see the "Pending configuration changes" message, select Yes to really apply changes
9. Go to Services > NFS > Settings and check the Enabled box
10. Click the Save button
11. Select the check mark icon to apply the changes when you see the "Pending configuration changes" message, select Yes to really apply changes
On the client side you need to make sure you have nfs support
1. Open a terminal and run the following command:
apt install nfs-common
2. You must mount the NFS share using the terminal before you can access the share in your favorite file manager. Example is an example of the commands to do that:
mkdir /tmp/b
sudo mount -t nfs 192.168.10.249:/export/demo /tmp/b
Replace 192.168.10.249 with the IP of your NAS server.
You can probably use the following command to find the IP (or you can login to your router and get a list of the dynamically allocated IPs that way which should include your Open Media Vault NAS server):
ping openmediavault.local
If you want the NFS share to be mounted on boot edit the /etc/fstab file like so:
sudo nano /etc/fstab
Then add the line for your server:
192.168.10.249:/export/demo /tmp/b nfs defaults,proto=tcp,port=2049 0 0
Again don't forget to replace 192.168.10.249 with your Open Media Vault server IP and a directory you've made (/tmp/b) and use of course the share name (demo) for the share you've created.
