I upgraded the firmware to 2.2.91 but after that, I’m not able to write / delete files to folders on DataVolume. After reading many posts here, I try to ssh into it and chmod on DataVolume, however got error below :
/ $ chmod 777 DataVolume
chmod: DataVolume: Read-only file system
It seems the DataVolume becomes read-only and I’ve no way to change it back to writeable on both ssh and web interface.
Anyone has idea how can get this fix without rebuild the volume or restor factory default?
