I have Transmission configured to save files to a UinionFS, suddenly it's unable to write to the downloads share anymore. I've reapplied ACLs but that made no difference. There is free space on all disks in the pool.
If I create a share on a different mount point (e.g. mdraid mirror) it works again, so it's just UnionFS. I can copy files to the downloads share over SMB as my own user account too, the UnionFS is writable.
Is someone please able to assist in getting this working again?
Edit: I've got it working by doing a chmod 777 on the downloads folder. Don't know why reapplying the ACLs didn't fix the problem so still curious if anyone has ideas about that. I wonder if somehow Transmission is running under a different user context, but not sure how to tell.
