POSSIBLE LOSS OF "EXEC" OPTIONS ON MOUNTED SSD
not much luck today second time typing this out .. first time didn't post.
After my unraid server froze and i had to do a hard reboot and (coincidentally probably) after the last UD update on the 16th, I seem to be having an issue where my plex media server "media scanner" crashes every night around 2 am. Plus i am now having playback errors etc. After talking with the Plex Media guys on their forum and looking at the Plex logs and crash reports. The said it looks like the disk the data is on "is no longer mounted with exec options". So my question is how can you tell if a mounted disk still has exec options (which i assume to mean execute or executive to allow permission to run what ever process or codec plex needs) and if not how to re-establish them on the disk. This set up has run with no problem for years so i don't think it would be the set up. Figure probably corruption or error from hard reboot though the disks and parity have all come back ok.
Below is the relevent post from the Plex forum:
The bigger issue is that wherever the PMS AppData is located it is no longer mounted with exec options. As you are using the 3rd-party unassigned drive plugin, I wonder if something changed recently with it. You could try reaching out on the Unraid forums to see if the issue is known there and can be resolved with another mount option.

The other thing you could do is upgrade to Unraid 6.9 RC2 and move your unassigned drive to be a second cache pool and then set Plex to be on that. It would function in the same way as the unassigned drives plugin, but would be mounted and handled by Unraid itself.
The core issue here is that ffmpeg and Plex require the ability to “execute” codecs, specifically EAE (Easy Audio Encoder) as this handles Dolby TrueHD/EAC3 decoding and encoding.
Any ideas?
Edit: did i post this in a manner that wasn't acceptable? Or is this something that is so obvious to everyone else it doesn't warrant a response? I see nothing that indicates where i could have removed or where to reapply execute privileges for the PLEX SSD mounted in UD. Is this something that can be found and fixed to your knowledge or do i just have to rebuild from scratch?
