Adding permisisons to new disk

[abasel]

I am using Ubuntu Desktop 9.4.

After reading various posts, I have managed to auto mount my 2nd disk.

I can however not create any folders or save to it; only browse.

I have tried the following but it doesn't seem to do anything

sudo chgrp users /media/disk-1
sudo chmod g+w /media/disk-1
sudo chmod +t /media/disk-1

Basically I want any user to be able to access and write or delete from the disk

Any ideas

[merlinus]

gksu nautilus

Navigate to the mountpoint, rightclick, properties, permissions.

gksu nautilusNavigate to the mountpoint, rightclick, properties, permissions.

+1 that should work

[abasel]

Still no joy, when I try change the group from root to users I get told that I don't have permission.. even when logged on as root.

I've tried making changes to the other options but doesn't appear to work. Are you able to give me more details?

Cheers

Try this:


sudo chown /mount_point your_user_name:your_group -rwxrwxrwx

This should allow read, write and executable permissions for owner, group and all others.

[merlinus]

What is the filesystem?

If spcwingo's suggestion does not work, you might try unmounting the partition, and then changing permissions with


gksu nautilus

[abasel]

Try this:


sudo chown /mount_point your_user_name:your_group -rwxrwxrwx

This should allow read, write and executable permissions for owner, group and all others.

But this will do it for a certain user, I want it to apply to all users in the "Users" group.

Did you see the second part of my post?

When I do

chown /media/disk-1 sysadmin:users -rwxrwxrwx

I get

chown: invalid option --'r'

I am using ubuntu 9.04

Finally got it using nautilus.

What I was doing wrong was trying to set permissions on the mounted disk, instead of unmounting it and then going to the actual mount point.

I would like to know what I was doing wrong with the chown command though.

Cheers and thanks for your patience.:popcorn:

You cannot change permissions on a non-linux filesystem if it is mounted. Perhaps that was the problem.

[abasel]

:(

Aaagh so it did not work. I must have been in an admin console.

I know it's not difficult... but have no idea what I'm doing wrong

[merlinus]

What filesystem does this use? You probably can add a line in /etc/fstab to mount the partition and set the permissions automatically.

Also, what partition is it, e.g. sdb2, and what mountpoint have you created? If you are not sure, post results of


sudo fdisk -l
df -h

[abasel]

The disk in question is sdb1

fstab

# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

/dev/sdb1 1 35698 286744153+ fd Linux raid autodetect

This line seems strange to me, since sdb1 is a fat32 filesystem, but linux is reporting it as linux raid autodetect.

[abasel]

As you will gather... Linux is not my forte... currently there is no data on the drive in question. I am quiet happy to reformat (would like it to be fat32 though so that I can still access it if my OS crashes) I just want the permissions fixed so that I can save to it.

I just need to know how :-)

[merlinus]

Why not ntfs? Linux has no problem reading and writing to that filesystem. It is also somewhat less prone to fragmentation, and can handle larger file sizes.

You can then install ntfs-config, which will give you a gui that will write the correct info to /etc/fstab.

[abasel]

K that's fine. I would prefer to do it from the command line. Up to now I have used the Linux partition GUI.

Could you give me the command?

[merlinus]

parted will not create an ntfs partition, but you can use it for fat32.

Why not use gparted?

[abasel]

I did use gparted, but will do so again, this time using NTSF.

Will have to do so tomorrow 5:12pm in NZ and I need to get my son home.

[abasel]

I've now installed ntfs-3g using http://ubuntuforums.org/showthread.php?t=217009

I've deleted my initial Fat32 partition but when I try to created the NTFS permission, the NTFS option is grayed out

[merlinus]

Can you be more specific? For example, are you trying to format the partition as ntfs, and if so, are you using gparted?

[abasel]

K.. got NTFS working, had to run

sudo apt-get install ntfsprogs
