HDD permissions issue, need some help.

Hiya,

Right me little home server has one final hiccup to overcome!

I have a 1 TB drive, mounted to mnt/storage1/ I have Chown -R mediatomb so the owner runs as mediatomb. This means that mediatomb can then scan my media correctly.

The trouble is changing the ownership of the 1tb drive from dean to mediatomb then borks the permissions for samba, ftp & sabnzbd.

Is it best to change the init script of mediatomb to run under dean user? or something else?

The trouble is if I change the init script to user dean and it said there was a permissions issue for sqlite database.

I'm abit stumped at the mo. Is it an issue with fstab? or is it because mediatomb init script wants to run under user mediatomb instead of my usual user dean?

Greetingz!

First things first, I'm going to assume that you're running an Ext2, Ext3, ReiserFs or other such UNIX-compatible filesystem that supports the standard UNIX ownership, group, and permissions models. If you're using a FAT32 or NTFS filesystem on the 1TB hard disk, please discard my advice.

(NOTE: to determine what filesystem is on the disk, once it's mounted, type the "mount" command and check it's output for that mountpoint.)

Typically, when you want to grant more than one user access to files, you would create a new "group" that both users were a member.

However, you may already have a generic group that many (if not all) of your users are a part of. Sometimes this group is called "Staff", other times it's simply "users".

I would strongly suggest using the "id" command to find out if the "dean" and "mediatomb" users share a group.

Note that it is possible to have a group named after a user, so there very well may be both a "mediatomb" user, as well as a "mediatomb" group.

The fastest way to find out would be to check your /etc/group file.

Hope this helps!

Code:

uid=1000(dean) gid=1000(dean) groups=20(dialout),24(cdrom),25(floppy),29(audio),44(video),46(plugdev),109(sambashare),111(mediatomb),1000(dean),1001(media_write)
dean@homeserver:~$ id mediatomb
uid=106(mediatomb) gid=111(mediatomb) groups=111(mediatomb),109(sambashare),1000(dean),1001(media_write)

Code:

dean@homeserver:~$ ls -al /mnt
total 12
drwxr-xr-x  3 root root        4096 2009-06-28 19:50 .
drwxr-xr-x 21 root root        4096 2009-07-08 11:34 ..
drwxrwxrwx  5 dean media_write 4096 2009-07-05 19:23 storage1
dean@homeserver:~$

I really dont get it. Media_write should allow mediatomb to read and write the drive but it can't.

Any ideas?

Fixed it!

Had to do this:

apt-get install mediatomb

cd /etc/init.d/

chmod -x mediatomb

chmod 777 mediatomb

sudo /etc/default/mediatomb

change group to media_write

edit this file to get avi support in ps3:

sudo nano /etc/mediatomb/config.xml

Instructions in this thread:

http://www.psu.com/forums/showthread.php?t=75619

sudo addgrp media_write

sudo /etc/group

add dean,mediatomb (to media_write)

sudo chgrp media_write /mnt/storage1

sudo chmod 770 /mnt/storage1 -R
