I was deleting a folder from a backup partiton. It took me too long, so I closed the filemanager wth Ctrl-Alt-Del and 'end process'. Probably this left the partition 'corrupt' because I can log in again, but only ' read', not 'read/write' . All partitions are in one TIB-volume of 285 GB. I have some 1 GB space left outside this volume. I ran the integrity check on the backup volume, and in the morning (it took some 4 hours) showd no error notifications on screen. So what to do now to be able to go in again with the read/write option?
