Partition Acces Problem

Mercurius · 06-05-2006, 04:17 AM

I have two DOS partitions which are mounted at boot time /dos/c and /dos/d I can write to them as root, but I cannot write to them as any other user. I dont know why this happends, tryed chmoding and chowning in root in recursive mode, but it does not change anything. I still get a permission denied error.

Hi,

You need to mount the DOS partitions with the user parameters - here's how I mount my VFAT USB disk:

Code:

/dev/maxtor /mnt/maxtor vfat noauto,owner,users  0 0

Check out the noauto, owner, users parameters - that should do the trick so that when you mount the DOS partition, you're the owner.

Where should I include this line? inittab in the /etc folder? Beacause the kernel mounts them on default.

Hi,

Sorry - forgot to mention that

The correct file is /etc/fstab

(inittab is where you control the different runlevels, and is where you change default runlevel from 3 to 4 to get it to boot into X windows - fstab is where you define the filesystems and such)

I have done that, and now I mount them manualy, but it is the same. I can only mount them as root (otherwise the mount command does not work). And even as root, when I try to change ownership, it gives me an permision denied error. What should I do?

Hmm, you included all the owner,users parameters?

What is the permissions on the device ? (/dev/hdx)

For my local vfat partition I use the options

Code:

auto,rw,umask=000

If you want to be able to mount as a regular user, and not automatically at boot time

Code:

noauto,rw,user,umask=007

should work. Since dos partitions don't allow permissions, Linux gives every file the same permission at mount time, and they can't be changed later (except with a remount). check the man page for mount for more info.

I want to mount it automatically at boot-time, but also write on it as a regular user, and have full privilages ...

So, after nine posts, could you please post your /etc/fstab file so that we can see what you have instead of letting others repeat the solution over and over again?

Here is the contents of fstab file

Code:

/dev/hda3        swap             swap        defaults         0   0
/dev/hda2        /                ext3        defaults         1   1
/dev/hda1        /dos/c           vfat        defaults         1   0
/dev/hdb1        /dos/d           vfat        defaults         1   0
#/dev/hda1        /dos/c           vfat        noauto,owner,user         0   0
#/dev/hdb1        /dos/d           vfat        noauto,owner,user         0   0
/dev/cdrom       /mnt/cdrom       auto        noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
none		/sys		sysfs		defaults	0   0

So, why did you not try the advice given in this thread and changed the above to

Code:

/dev/hda1        /dos/c           vfat        rw,umask=000         1   0
/dev/hdb1        /dos/d           vfat        rw,umask=000         1   0

That should work.
