Does it possible to mount one disk image to some target point?

[Dmit]

Hello All!

I try to mount one disk image to two points.

sudo mount -o loop,user,uid=dm /home/dm/mmm/test_drive1.img /home/dm/mmm/fs
sudo mount -o loop,user,uid=dm /home/dm/mmm/test_drive1.img /home/dm/mmm/fs2

Thats done

But when i create,copy or change anything on one mount point (../fs) its not updates on second mount point (../fs2).

Does anyone know way to 'share' one disk image (.img) to some mount points?

Thanks for all!!!

my first thought would be to use links, but I am unsure weather this would accomplish your goal. I am also unable to test this currently, so the commands may be slightly different.


mount -o loop,user,uid=dm /home/dm/mmm/test_drive1.img /home/dm/mmm/fs
ln /home/dm/mmm/fs /home/dm/mmm/fs2

There may be much better ways to do this. I am still getting used to certain things in linux, and do not have very much exposure to this sort of stuff

This is very dangerous. You are likely to end up with a corrupted image. Mount to one (common) point, and then make the other one a soft link to that one. Multiple mounts to one hardware device is ok, but to a disc image file I think you are asking for trouble.

Hi Dmit,

Maybe the -B, --bind mount options.
