Hello,
I'm getting permission errors when trying to run a new backup or do a manual garbage collect. I've compared the folder/file permissions with a different user that works but I don't see any difference.
Any advise?

Code:
Garbage collect log:

2022-06-09T16:43:08+02:00: starting garbage collection on store frits

2022-06-09T16:43:08+02:00: Start GC phase1 (mark used chunks)

Hi,

can you post the permissions you checked as well? :)
Sure thing!
drwxr-xr-x 4 backup backup 6 Jun 2 00:28 frits

drwxr-xr-x 4 backup backup 6 Jun 2 00:28 .
drwxr-xr-x 10 root root 10 Jun 9 15:35 ..
drwxr-x--- 65538 backup backup 65K May 30 10:06 .chunks
-rw-r--r-- 1 backup backup 305 Jun 2 00:28 .gc-status
-rw-r--r-- 1 backup backup 0 May 30 10:06 .lock
drwxr-xr-x 3 backup backup 3 May 30 10:33 vm


Also looked at the other threads regarding this issue but I did not manually remove any chunk files or anything :)

Yeah as you said they look like mine too :).

Did you also check the folder .chunks for their permissions. Best both of the ones you posted errors for ls -ld .chunks/004f .chunks/001e, and also for the files in those folders.

Hey thanks!
The ownership of the files in 004f are from a completely different user. The strange thing is that this user doesn't even have access to this folder.
Time for some more digging. Thank-you for the pointer.
