I'm not entirely sure why this is happening but it seems to only happen with the "Homes" shared folder, which I have enabled for user homes.
Rundown....
"Homes" shared folder created and pointing to the "/srv/XXXXXXX/homes" folder on the filesystem (it's a mergerFS filesystem so the ID is long).
Plenty of other shared folders created under this same /srv/XXXXXXX/ location as well
Under users > settings tab > enabled homes folder and point it to that Homes shared folder.
SMB/CIFS under Home Directories, I have it enabled
Every single time I reboot the server, I lose the Homes shared folder, which of course breaks access to users shared folders. I can try to browse /sharedfolders/Homes and it's completely empty. All of the other shared folders are fine.
To fix it, I go to Shared Folders, edit the Homes shared folder, everything is correct. I browse anyways to "point" it back to the location, even though it's the same location as when it was originally set. Save, then apply. And magically it's working again.
And.....now that I'm typing all of this. I decided to check my /etc/fstab and there isn't an entry for the Homes shared folder. There's one in for all BUT that one, even though I set it every single time I reboot. Is there a reason this isn't getting applied to fstab?
Edit: Nevermind about fstab. I just realized those are my NFS shares.
