Ubuntu install to symlink failing

Plex Media Server
1

Server Version#: 1.30.0.6486-629d58034

I am trying to avoid installing on the OS logical volume. I setup a symlink, (i have tried relaitve and non relative)

ll /var/lib |grep plex
lrwxrwxrwx 1 plex plex 31 Dec 28 16:41 plexmediaserver → …/…/apps/plex/plexmediaserver/

When i try to install i get the following:

PlexMediaServer install: PlexMediaServer-1.30.0.6486-629d58034 - Installation starting.
PlexMediaServer install:
PlexMediaServer install: Now installing based on:

The better/easier way: Customizing your Plex configuration on systemd based systems

I created the override with the variable mentioned :
Environment=“PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/home/plexdir/Library/Application Support”

When i try to install i again, i see this in the service failure output:

A start job for unit plexmediaserver.service has begun execution.

░░ The job identifier is 10665.

Override file

Move the data directory

Environment=“PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/apps/plex/plexmediaserver/Library/Application Support”

I see it still creates /var/lib/plexmediaserver – Are there other variables i need to add to have the application live on another LV?

Remove the override.conf file.
Install Plex normally

apt install plexmediaserver

This will create the plex user and systemd entries. Stop plex

systemctl stop plexmediaserver.service

Now where did you mount the non OS drive and what is the fstab entry?

5

its mounted to /apps/plex/plexmediaserver

6

Then your variable should be:

Environment=“PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/apps/plex/plexmediaserver"

This cannot be a network drive.

How did you create this mount (all the steps). Or you can read the other Linux Tips.

7

It was created as logical volume from the volume group from the local disks.

19 lvcreate -L 50G -n plex-lv ubuntu-vg
20 pvs
21 lvs
22 mkfs -t ext4 /dev/ubuntu-vg/plex-lv
23 mkdir /apps/plex
24 vi /etc/fstab
25 mount -a

8

So the process should look like this:

Install as normal
Stop Plex
Create override file with enviornment
Move /var/lib/plexmediaserver/* to /apps/plex/plexmediaserver/
Start Plex

9

If you did the default install then:

umount /apps/plex
chown -R plex: /apps
mount /apps/plex

Yes.

I got that to work, Thanks!
