Dear All,

I have mounted a floppy image file as below

$> su
$> /sbin/losetup /dev/loop0 /mnt/win_e/images/grubdos.img
$> mkdir /mnt/floppy
$> mount /dev/loop0 -o loop /mnt/floppy

Floopy image mounted on "/mnt/floppy", now I have tried to create a file inside the floppy image, file created successfully, however I can not change the ownership of the file.

$> cd /mnt/floppy
$> touch hai.txt
$> ll hai.txt
-rwxr-xr-x 1 root root 0 Mar 8 17:29 hai.txt
$> chown user1:user1 hai.txt
chown: changing ownership of 'hai.txt': Operation not permitted

How to change the ownership of the file and folder in mounted floppy image ?

Hi,
From the ls-ltr i see the file hai.txt has root as its group & owner. you didn't say what linux you are using. You need root privilages for changing the ownership

login to root and try

#chown user1:user1 hai.txt

or try with sudo command
$sudo user1:user1 hai.txt

Thanks for your reply.

In the very first line itself, I have entered as root user.


I am using CentOS.

hi,
Try using su - instead or login to root account and see if it works
