Hi all - I am looking to build a new UnRAID Plex server soon. The purpose of it is to host a Plex media server. Easy enough. The storage disks will be 5400 RPM. I am wondering if I should spring for my parity drives to be a bit faster in the event of a parity rebuild. Would it help with the speed of the rebuild effort, or does it just not matter?

Is there any reason to this? These are just media files, not an always-persistent, mission-critical financial database. You are doing mostly reads and minimal writes. Your protection is wrapped around the parity drive and any backups you are doing external to the server. ECC provides none of that value. The only group that I really know of that really touts this as something that should be required are the FreeNAS people, and it just isn't necessary for home consumer use, and will save you a lot of money. Edit: Unless you're hosting the storage on a filesystem like ZFS that would benefit from ECC. But stock XFS or even EXT4 are just fine for your use case. No need to overengineer it (and TRUST me, I have a habit of doing that myself).

That video is accurate up until it tells you to go into a terminal and start mucking around on the command line. NVDEC must also be enabled in Plex itself. Good luck!

Yes. Thank you!

I can verify that my Plex sqlitedb has not had an issue ever since I moved it to my SSD cache drive and off of my spinning disks in the main array. I did this before I even knew about this thread / posts on Reddit about this issue. I rebuilt and rebuilt, but every day or two the database would become malformed. It's been up and stable for weeks now. Shame, I lost a lot of user data, and since the backups were stored on the spinning disks they, too, were toast. My fault, I should have kept better backups, but it is what it is.

I have this problem for an onboard Intel GPU. I have no intention of passing it through. It is in its own IOMMU group. Would there be any way to just not use this IOMMU group entirely? As others have said, this is the top result when looking for this issue so any help would be appreciated.
