[SOLVED] Changing group ownership.

[Aximilli]

I'm attempting to use 8.04 server edition to make a centralized storage computer in my house, and I've encountered a pretty big problem right off the bat.

The storage partition on my first drive is mounted into /share/public (which i created). I made a new user group to include the other members of my house, but when I try to change the folder's group ownership I am denied, even as root.

root@storage:/# chgrp 666 /d1storage/ -R
chgrp: changing group of `/d1storage/music': Operation not permitted
chgrp: changing group of `/d1storage/installers': Operation not permitted
chgrp: changing group of `/d1storage/video/gamow.wmv': Operation not permitted
chgrp: changing group of `/d1storage/video': Operation not permitted
chgrp: changing group of `/d1storage/': Operation not permitted

this method doesn't work either.

root@storage:/share# chown -hR alex:sharers /share/public/
chown: changing ownership of `/share/public/music': Operation not permitted
chown: changing ownership of `/share/public/installers': Operation not permitted
chown: changing ownership of `/share/public/video/gamow.wmv': Operation not permitted
chown: changing ownership of `/share/public/video': Operation not permitted
chown: changing ownership of `/share/public/': Operation not permitted

I can't figure out what I'm doing wrong. Sorry to be such a noob, but I need to get past this.

Thanks
Alex

Either become root or use sudo in front of the command.


EDIT: Didnt read the last part. Unmount the share, chown it, then remount.

[Aximilli]

Please take a look at the code. note that I am logged in as root.

I'm noob, but not that noob

EDIT - ok saw your edit, trying that now, thanks

[Aximilli]

Awesome, thanks so much!

I spoke to soon on this one. When I unmount and run a recursive chgrp on the parent folder of the mount i get no errors, but when I remount the folder is still owned by the plugdev group, not my sharers group. Any more thoughts?

To change group ownership, follow this format:

sudo chgrp system_groupname /location_of_files_or_folders

I thought it might help to show step by step what is happening to me.

I assume this means that at every reboot the folders group ownership will change back to plugdev. I hope this information is helpful, despite being overly verbose.

Thanks a lot for your time.

To change group ownership, follow this format:

sudo chgrp system_groupname /location_of_files_or_folders

I do believe that is the format I'm using, is it not?

well, Yay. My thread has just been spammed. Yippy for me.

EDIT: Looks like this guy is spamming alot of other threads. Ban time.

Don't worry, he's been taken care of. But in future, if you actually want spam to be taken care of then you should report it instead of going around posting threats to the spammer since it is pointless and is just wasting time.
