Seems I spoke too soon and that didn't survive a reboot.
I have mirrored my old HC-2 system and everything appears to be identical. I can access my share fine from my media devices, but I can't get it to mount on my Linux box.
Here is the fstab on my client machine:
I still can't delete the shared folder from the OMV5 gui as it's still greyed out.
Here are side by side of my nfs shares, and shared folders.
The directory structures are exact other than the names. Media on my old NAS, and MEDIA2 on the new one, but somehow when I choose "Select a directory" from the folder share screens, I'm not at the same level.
I am able to mount the root directory, but not the MEDIA2 directory as intended.
So my old NAS mounts to my /mnt/Media folder on boot every time.
I could really use some help.
EDIT: I was finally able to delete the Access Rights > Shared Folder by deleting the NFS share first.
So with no shares now, I still can't select my MEDIA2 folder as the folder to share. It wants to share a folder from within that folder.
