i received the message: adding read ACL for uid 1000 to '/media/david' failed

I'm stumped what command must i use in ubuntu please.
I feel embarassed about this as i read wiki for commands but exited none the wiser!
I guess this is rather basic but i''m stumped!

David.

What command(s) did you execute and where and how this error is generating? Please explain it little more, so we could help you.

no command given

in fact i to get this message i did not enter any command. I simply go to my home folder where all partitions are listed and click any one of them and u get this error.
i suppose there is a system error in ubuntu and it is issuing some command.
If i use open suse (also on the same harddisk) it also sees all of the partitions and there if i click on them it automatically mounts the partition and presents the contents.
I suppose ubuntu is trying to do the same but using the wrong command. I am unable to say what command , i haVE TRIED MYSELF SETFACL AND CHMOD BUT I'M NOT AN EXPERT OR KNOWLEDEABLE WITH THESE COMMANDS AND THEIR DESCRIPTION IN WIKI LEAVES ME COLD.
i READ SOMEWHERE THAT A SIMILAR PROBLEM WAS REPORTED IN SLACKWARE.

What does it say?

Code:

~$ df -h

~$ cat /etc/fstab

----hoping this throws some light on it!

this request is still not answered - i am desperate to resolve it
please help

Dave.

Try:

Code:

~$ mkdir /media/david

~$ chown david:david /media/david

~$ chmod 750 /media/david



~$ mount -t <fs-type> /dev/<device> /media/david

Then connect your HD or device again and try to boot.

I think you need to check if acls are enabled on that partition eg

Code:

tune2fs -l /dev/sda1 | grep options

Amend /dev/sda1 to match your system

Are you trying to mount an external HDD to /media/david?
Can you post the output "sudo fdisk -l" command?
If External HDD is formatted using NTFS filesystem then you need ntfs-3g package to mount NTFS partitions. So check whether that package is installed or not using

Code:

sudo dpkg -l | grep ntfs-3g

If it is not installed, install it using below commands

Code:

sudo apt-get update

sudo apt-get install ntfs-3g

After installation you can mount that NTFS partition(which will be usually sdb* or sdc*) using below command

Code:

sudo mount /dev/sdb1 /media/david -o uid=1000,gid=1000,dmask=027,fmask=027

or

sudo mount -t ntfs-3g /dev/sdb1 /media/david -o uid=1000,gid=1000,dmask=027,fmask=027

dmask is the mask for directories and fmask is the mask for files.
Here you no need either extra ACLs or chmod/chown commands to give read/write permissions to uid=1000, From above command by default the user & group who is having uid & gid as 1000 will get read, write & execute and read & execute permissions respectively to /media/david folder including all sub folders and others won't be having any permission on /media/david.
You can change permissions according to your needs by calculating with umask i.e

Code:

7 7 7  ---> full permission for all

0 2 7  ---> umask of owner, group and others

-----

7 5 0  ---> real permissions of files/folders of owner, group and otheres.

| | |-->Other don't have any permissions.

| |-->Group having read and execute permissions.

|-->Owner having full(read/write/excecute) permissions.



4 = read

2 = write

1 = execute

---------

7 = rwx

---------

If you are just trying to give access to /media/david folder without mounting any external HDD, then you can do it using chmod/chown only but ACL would be fine which can set particular permission to particular user even that directory is not owned by either his name/group. Before running setfacl command make sure whether acl package is installed.

Code:

sudo dpkg -l | grep acl

You can install ACL using

Code:

sudo apt-get install acl

If ACL is not enabled for / then open /etc/fstab file and add acl to the end of the 4th field in the / partion line. Then your root partition line looks like below

Code:

UUID=e087b5ed-bcc7-416c-a1fa-4c80bb3a1082 / ext2 errors=remount-ro,acl 0 1

Now remount / using

Code:

mount -o remount /

Check whether now ACL is enabled for /.

Code:

mount | grep acl

Now you can run setfacl command

Code:

setfacl -m u:username:rwx /path

setfacl --help

For example

setfacl -R -m u:david:rwx /media/david
