New PMS install on Ubuntu, cannot mount existing share on Synology

Server Version#:plexmediaserver_1.28.1.6018-c1f308c6a_amd64
DSM 6.2.4

I am trying to configure PMS on Ubuntu and map libraries to an existing share on a Synology DS1515. Previous setup was Windows server. I am unable to mount using NFS or CIFS, and not exactly sure which I should aim to use. Existing NAS volume is formatted ext4.

Happy to provide any further information, thank you.

Additional details:

Error attempting to mount:

$ sudo mount -a
mount.nfs: an incorrect mount option was specified


New line in /etc/fstab:

192.168.1.147:/volume1/a /home/aal/media/plex/ nfs credentials=/var/lib/plexmediaserver/.mountaccess,nounix,iocharset=utf8 0 0

@trichome

sudo apt install nfs-common

Also remove the credentials statements.

all you need are nfs defaults,auto,rw,nofail,bg 0 0
NFS client tools are not part of the standard Ubuntu distro (insane for Linux not to have NFS)

I’m a little confused about why you’re trying to configure PMS on Ubuntu when your media resides on a Synology DS1515. Why not simply run PMS on the Synology?

I run my PMS on my Synology DS1019+, in fact in a Docker container. I export the /volume1/Media from my Synology by having this in /etc/exports on the Synology:

/volume1/Media	192.168.0.0/24(rw,async,no_wdelay,no_root_squash,insecure_locks,sec=sys,anonuid=1025,anongid=100)

(Your path would apparently be /volume1/a). I then run sudo exportfs -a, This exports this filesystem to all machines on the local LAN.

I then NFS mount it to my Ubuntu machines. My /etc/fstab contains:

jupiter:/volume1/Media		/nas    	nfs defaults,async

For me, jupiter is in my /etc/hosts so I can use the name instead of the IP address under /volume1/Media I have Videos, Pictures, and Music. On my Ubuntu machines I have symlinks that point /Videos -> /nas/Videos, /Pictures -> /nas/Pictures and /Music -> /nas/Music so I have convenient short paths to those areas.

Also, your /etc/fstab has the option for credentials. I don’t think that’s valid NFS option rather that’s an option for a SMB mount. Try defaults,async instead

Isn’t everybody just using SMB nowadays (even though it’s a lot slower)?

@adefaria

NO. SMB is a PITA

Using a Windows protocol for Linux - Linux is nonsensical

@trichome

Additional info for you:

I’m 100% on your side, Chuck. I was being extremely sarcastic - sorry that didn’t show through. There’s no SMB in my house, no Windows ('cept in a VM that I hardly ever run) and everything is NFS.

Not sure how I didn’t find this looking through the forum pins, but very helpful, thank you.

I was able to mount everything on first try except the ‘photos’ example as I did want to take that same approach making that RO. I will revisit that later and check my work. But everything else is mounted and added to PMS.

Very much appreciate the quick, thorough response.

Thank you for the reply.

I must admit, I haven’t even considered my PMS setup for several years now, so I’m happy to be wrong if this setup no longer makes sense.

My understanding was that running an NVIDIA P2000 GPU (which is what the Ubuntu server has) would perform better transcoding remote streams than the DS1515 would. That said, I have never even attempted to run PMS on the DS1515, so I am admittedly quite out of touch with PMS these days.

Thank you again for your reply.

Given you have a P2000 and a (presumably) reasonable CPU in the Ubuntu machine,
it will perform much better than the Synology with HW Transcoding (DSx15+ has none), Audio conversion and, most definitely, subtitle burning (if needed).

The DS1515+, like my DS1815+ is good for:

  1. DirectPlay
  2. Some audio conversion
  3. Fantastic NFS file serving.

… and that’s where it stops
