[opensuse] mounting read only as root
Hello, I often have to use "rsync --delete" to mirror two very large archives usb disks. for safety reason, I would like to mount the source read only. usually I just mount disks in dolphin and use rsync from dolphin xterm. But like this disks are mounted rw is there a simple way to mount a disk ro as user? in Dolphin, the action seems to be done by kde-open5, but options do not show ro options] urls...

thanks jdd
Interrims solution, if your source has a consistend mount-point: Create a [nice-name-here].desktop file / starter with the following EXEC= line: EXEC=xdg-su -u root -c /usr/bin/mount -o remount,ro [source-mount-point] Not the nicest (ask for root), but works for sure. Plug the disk in, (it will be mounted read-write), then use the created "program" from above, which will change the drive from read-write to read-only. (You can validate that with a simple call to "mount" in a terminal) Then you can operate (more) safely. - Yamaban.

I'd maybe add such a line to /etc/fstab to bind-mount the mount point over itself with the read-only option set: /mnt /mnt none bind,ro,user 0 0 Have a nice day, Berny -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

thanks, but the udisksctl is exactly what I needed :-)) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The tool udisksctl is for non-root users and IIRC dolphin uses the udisks API for mounting. So, this might work for you: udisksctl mount --block-device /dev/sdaX --options ro Gruß Jan -- Don't put animals with sharp teeth or poisonous fangs down the front of your clothes. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

YES! that's the solution; I even can use /dev/disk/by-label/xxxx as it will probably always be the same source (to various targets) thanks, I didn't know of udiskctl! jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
