Hello,
I have a similar problem - using a Raspberry PI with Raspbian and a USB hard drive attached to it to sync files from my Synology NAS to the USB drive. The drive is mounted on the Raspberry by user pi to /media/pi/Sync and sync tasks have been created on both the Synology NAS and the Raspberry, but sync does not work due to "locked files" and permission issues on the USB disk drive. I already treid to add the user rslsync to the group of the user pi but with no effect, still same problem.
Any hints on how to solve this?
Thanks a lot!
