Changing Permissions Problem

#1 (**permalink**) 31-Aug-2006, 05:14

Hi,

I got a problem with permissions. I have a partition with data (let's call it /home/{user}/DATA), which originally had {user} permissions. However, after some moving/coping of files under root from terminal, the permissions of all this whole partition became Group: users and Owner: root for all the content.
And unexpectedly, I cannot change the permissions (e.g. ' chown -R {user} /home/{user}/DATA ') as root !!!
It gives: " chown: changing of permissions ...... : Operation is not permitted " for each file !
I tried also to change the permissions from Nautilus- or Konquerror- superuser and it again gives "Access denied" for a superuser !
So, I'm in serious trouble.
If someone knows what's going on ?

Thanks

What type of filesystem is the partition? Ext3/XFS/ReiserFS or NTFS/Fat32 (i.e. Windows or Linux)? It sounds like the filesystem is not a type that supports Linux Permissions, like a Windows filesystem. If you:

Code:

 # mount

It will tell you what type it is.

fat32

That's it, then. Well seen Zombie13!

Adding "users" to the mounting options for that partition in fstab should solve that.
Post it if you will.

it's been done by default

Copy the contents as the user to a partition with the user's rights. This will make
the ownership the users....then you can copy them back AS THE USER to the fat32
partition..and it will have your permissions. However, keep in mind that you will NOT
be able to change the attributes of the file (UNIX permissions) when it is on the
non-supported file system.

This should work for you. Also, in your fstab, I would ad "exec" to your file
system attributes...so that executables are workable...if that is desired...

Good luck!

the "users" option was there from the beginning (from the very installation I guess)

users,gid=users,umask=0002,utf8=true

I'm not very familiar with the most options... but anyway
