In the future, do not install operating system updates, beta or otherwise, without confirmation that your necessary applications are supported. In the past, even non-beta updates from Synology have caused issues with Plex.
As for now, you may be able to start Plex from the command line. See this thread:
You might also try running Plex via docker on DSM 7 Preview. I donât know anyone thatâs tried it yet, but my suspicion is itâd work as well as on docker on DSM 6 (which means youâll loose hardware transcoding without jumping through hoops). If youâve already updated to the DSM preview though youâve got nothing to loose. There is no published timeline, but DSM betas are typically pretty long and my guess is DSM 7 RC and Plex support for it is 6 months away.
This might get your started, but there are dozens of other good threads and pages. Synology Plex and Docker
Weâve been in contact with Synology and are following DSM 7âs progress.
Iâve been dedicated this week so far to making a DSM 7 version of PMS.
It is turning out to be an extensive overhaul.
There are going to be incompatibilities.
There are going to be some mandatory changes.
I am concerned about a few things:
Folks with extensive metadata libraries and migrating that volume of data into the new structure
The amount of abstraction / insulation DSM 7 SDK creates. It will solve a lot of the accidental problems weâve seen (co-mingling of data and media in the Plex share and what happens when mistakes are made) but â
How to backup and restore metadata once migrated.
How to effect database repairs
Todayâs tasks:
Access when PMS wonât start â
I think Iâve resolved the âLogfiles when PMS isnât workingâ problem. Thatâs todayâs effort
Hi @ChuckPa thanks for sharing the roadmap to DSM7. Iâm one of the DSM7 Preview Release testers, and Iâm running Plex 1.20.1.3252 through the CLI start workaround. Is the community able to help somehow?
Great to hear Synology already has something to validate, thatâs promising news! Count on me (hopefully on us all) to beta test this new packaging approach.
Iâm not running the latest and greatest, unfortunately. The DSM7 testers are stuck into 1.20.1.3252, which was the latest one available before DSM7 preview came. I donât know how to do the âunpack and root dropâ, and in fact Iâd like to keep it that way, so I can fully cooperate with Plex efforts on testing the new release, when Synology gives you their signoff.
Keep up, and count me in during the testing phase! Thank you.
Thatâs two great news in one! First, Plex will be available to beta users - and this will encourage more people to join and test it out - and DSM7 will go beta in a couple weeks - this will address lots of bugs already reported by all of us running the Preview. Looking forward to deploying it!
