plex error #4000

ftriscari · 26. September 2014

Hi I freshly installed OMV 1.0.
Plex installed without problems but when I try to enable it I get the following error

Code

Error #4000:

Plex was already installed on OMV 0.5 and I'm now trying to use the same database folder....

Thanks

Browser cache maybe? Try opening your browser in Incognito/Privacy mode, and see if it works... if it does.. It's a cache issue. Usually anytime I get a weird error after a clean install... that's the first thing I check.

I'm afraid it doesn't work...
under the running services tab, the plex service has a nice red spot.

from the command line

Code

root@openmediavault:~# service plexmediaserver restart
Plex Media Server is not running (no process found)...
Starting Plex Media Server: done

Guys, do you have any idea on how to solve this issue?
is anyone else experiencing the same issue?
thanks

Is the plex server running then from what I see in you command service restart? Can you actually access through "http://IP_OF_OMV:32400/web/index.html" ?

what's the output of ps ax | grep -i plex?

ftriscari · 29. September 2014

I can't access plex...

Code

root@openmediavault:~# ps ax | grep -i plex
 4564 pts/0    S+     0:00 grep -i plex

Back up your folder db first to some other location so you don't loose it. Try and set a new db manually to check if you can start the server in the first place.

you can do that edit that in /etc/default/plexmediaserver and uncomment

PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/media/{uuid-disk}/plextest # don't forget to replace the uuid number of your disk

create the previous folder and chmod -R plex:nogroup /media/{uuid-disk}/plextest

start the server again and see if it works now.

I found the problem!! the permissions of the plexmediaserver folder were wrong... I had to chmod -R 777 the folder and now it works...
you put me on the right track. thank you!!

Don't know if they have to be that wide open, but the plex user must be able to rw. PMS daemon runs under plex user unless is changed in the config.

ryecoaaron · 29. September 2014

You can make them 777 but they still aren't executable because the drive is mounted noexec. So, probably not much danger.

You only neeed "chmod -R 775". If you do 777 a user could possibly delete your folders/files from the plex interface. This is not desirable. It is better to delete things behind the scenes then risk that any user could delete things. Even with a chmod 775 on the shared folder the files/folders added/created via the samba share will follow options in the smb.conf, for the samba share in question.

Strangly running an ls -l I found that the owner of the folder was set as Btsync and the owner was nogroup! ...I don't know what happened!
I realize that 777 was overkill...I just wanted to make sure that it worked.
I'll revert the plex database folder to 775.

Just to check, what owner/group should I have for the plexmediaserver folder?
Thanks

chown -R plex:nogroup /media/uuid/plexmediaserver(the correct path to this folder)

Jetzt mitmachen!
