Library won't scan; permission denied despite setting up permissions as described

I’m a noob. I installed the latest Plex Server 1.26.2.5797 from scratch and built my libraries brand new. I’ve set up 2 libraries so far: Home Videos, and Movies. I’m having a problem where Plex won’t scan one library (Home Videos), but is scanning the other one just fine (Movies).

I set the permissions as described in the popup: (Synology → Control panel → Shared Folder → Edit → Permissions → System Internal user (in the drop down) → Plex set to read/write)

Here’s the error I’m getting in my log file:

May 31, 2022 10:48:09.298 [0x7f91cc6c8b38] ERROR - Couldn’t check for the existence of file “/volume1/photo/Phone Backup Pics and Vids/.grab”: boost::filesystem::status: Permission denied: “/volume1/photo/Phone Backup Pics and Vids/.grab”

Plex is able to scan my Volume2/… directory just fine. I set permissions here the same way.

I’ve uploaded my logs. Any help would be appreciated.

I’m not very technical, so a dumbed-down explanation/troubleshooting guide would be very helpful.

Double checking:

  1. System Internal User PlexMediaServer (old “Plex” user is abandoned from DSM 6 and can be removed)

  2. Did you check the box to “Apply to this folder, sub-folder and files” as you set the new permissions?

Thanks @ChuckPa

I’m not seeing a “Apply to this folder, sub-folder and files” checkbox options in my /Volume1/photos Properties>Permissions tab.

permissions 1
permissions 1749×585 36.8 KB

I DO see this option in the other directory that’s being scanned properly:

permissions 2
permissions 2749×590 31.8 KB

In the bottom picture… Lower Left corner is the checkbox.

“Apply to this folder, sub-folders and files”

Check that box.

SAVE

You can also do this from FileStation.

Right click on “photo” (left pane of FileStation) → Properties → Permissions.

That might be easier to navigate / see how to do this.

(they make it weird)

Apologies for the confusion. I’m saying that the checkbox for “Apply to this folder, sub-folder and files” checkbox” is not available/does not show up in the /Volume1/photos Properties > Permissions tab, however this checkbox is available on the /Volume2/ Properties > Permissions tab. I checked it and saved, although this did not fix my problem.

Is that the Synology-provided “photo” shared folder
–OR–
Do you have Photo Station installed ?

Either of those conflict (Synology does weird things / doesn’t let go of permissions)

If the above is true, Create a new folder “Photos” and move your photos there.
As you create it, grant PlexMediaServer permission
Then move all the files over and add the folder to Plex.

Both of the above are true. I’m going to try creating a new “Photos” folder and move everything over, and grant permissions as you advised. I’ll report back with my findings. Thanks so much!

Hey @ChuckPa thank you for your help! I created a new folder, moved all of my stuff there, and granted permissions as advised. Plex is now scanning that new folder successfully.

Glad you got it resolved. It’s unfortunate DSM behaves that way but :man_shrugging:
