Hello You suggested that I use a file to simulate a partition. I could not highlight the incident.
However, the commands you offer can also be used with a partition. So I no longer need to use gparted. This highlights that it is the resize command that destroys the partition. Here is the trace below and also in attached file ______________ UNDER UBUNTU1910 . sudo -i export LC_ALL=POSIX mount /dev/sda1 /mnt ls -ls /mnt total 28 4 drwx------ 20 root root 4096 Jan 5 12:54 P2 4 drwx------ 20 root root 4096 Jan 5 12:59 P3 4 drwx------ 20 root root 4096 Jan 5 13:04 P4 16 drwx------ 2 root root 16384 Jan 5 12:38 lost+found umount /dev/sda1 e2fsck -f /dev/sda1 Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information bug_1857914: 11765/3932160 files (0.4% non-contiguous), 11842526/15728640 blocks resize2fs -p /dev/sda1 50G resize2fs 1.45.3 (14-Jul-2019) Resizing the filesystem on /dev/sda1 to 13107200 (4k) blocks.
