Someone on the Raspberry Pi Forums said: uid= and gid= are not valid mount options for ext2. ext2 (like ext4 which I'd use) has full, native support for linux owner, group, and permissions so you cannont change them at mount time via mount options. * Use the PC to reformat to ext4 (I did ext2) * Mount the partition on the PC * sudo chmod 777 /path/to/mountpoint so permissions on it are fully open to all users. Unmount and unplug it. Connect it to the Pi and Mount with: *sudo mount /dev/sda1 /media/usb/ That worked. :-) Thanks to all who offered suggestions. -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-12-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

Actually, I think thayt might have been a red herring. No ext2 filesysrems are defined in fstab: pi@minster-music:/etc $ cat fstab proc/proc procdefaults 0 0 PARTUUID=c6b26c9a-01 /boot vfatdefaults 0 2 PARTUUID=c6b26c9a-02 / ext4defaults,noatime 0 1 # a swapfile is not a swap partition, no line here # use dphys-swapfile swap[on|off] for that -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-12-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

Well according to the man page that should do something legal: sudo mount -t ext2 /dev/sda1 /media/usb/ -o uid=pi,gid=pi but I get the same result. I get the same if I put the switch after the mount point and I get 'bad usage if I write: sudo mount /dev/sda1 /media/usb/ -o,-t ext2,uid=pi,gid=pi -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-12-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk

[Dorset] Problem Mounting Memory Stick on Raspberry Pi
Hi, I've been trying to back up a Pi installation using a tool called image-utils (written by a contributor to the Pi Forums). This tool backs up the running system and writes the image to a specified destination. I've used it many times before but I recently had an issue because my image file was bigger than the 4 GB limit on FAT32. I was advised by the author to format the stick with ext2. This I have done, but can no longer mount the stick on the Pi. Initially I thought that the problem was due to ownership and permissions; formatting creates a partition owned by root. I've now changed ownership and permissions on the stick (labelled Backup) to: drwxrwxrwx 3 terry terry 4096 Nov 28 13:04 Backup using my PC. However, I still get an issue when I plug the stick into the Pi. Having created the directory /media/usb/ on the Pi, I do: pi@minster-music:~ $ ls -l /dev/disk/by-uuid/ total 0 lrwxrwxrwx 1 root root 10 Nov 28 13:05 5183463e-4eee-4e13-99c2-f0871ad6d8b8 -> ../../sda1 lrwxrwxrwx 1 root root 15 Nov 28 11:10 568caafd-bab1-46cb-921b-cd257b61f505 -> ../../mmcblk0p2 lrwxrwxrwx 1 root root 15 Nov 28 11:10 C839-E506 -> ../../mmcblk0p1 then I do: pi@minster-music:~ $ sudo mount /dev/sda1 /media/usb/ -o uid=pi,gid=pi mount: /media/usb: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. As you can see, the Pi doesn't like this. This procedure works if I use a FAT32 Stick. What have I mised? -- Terry Coles -- Next meeting: Online, Jitsi, Tuesday, 2021-12-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
