Submount, "permission denied" when writing to floppy as normal user

DaneM · 08-18-2005, 08:50 PM

Hello, everybody.

I'm using Slackware 10.1 with kernel 2.6.12.4 and Submount 0.9. Whenever I try to write to /mnt/floppy (while mounted) I get this error:

Code:

<~/tmp/submount-0.9-33/submount-0.9/subfs-0.9>
[dane@Orchestrator subfs-0.9]$ touch /mnt/floppy/foo
touch: cannot touch `/mnt/floppy/foo': Permission denied

My fstab entry is as follows:

Code:

/dev/fd0 /mnt/floppy subfs fs=floppyfss,user,rw,iocharset=iso8859-1,sync,umask=0 0 0

Any ideas? Your help is well-appreciated.

Here's the solution:

Same fstab entry.

Do this:

Code:

cd /mnt
chmod 666 floppy
cd floppy
chmod 666 .

I don't entirely understand why this works, but somehow it does! (The first chmod alone didn't fix it for some reason...)

Hopefully this will help somebody with the same or similar problem.

Thanks for the courtesy of posting your results, so few do.

I think you could combine your solution into 1 line:

Code:

# chmod -R 666 /mnt/floppy

While this doesn't do exactly what your code did, it may be what you really need -- any sub-dirs on the floppy as well the root.

However, I think the correct & permanent fix lies in your fstab; possibly in the umask, or maybe in the UID / GID. Suggest you take a look at the fstab & mount man pages. I don't do floppies or Slack enough to offer you the specific advice you really need, sorry.

Thanks for the input. Now that I think about it, I believe that that chmod command could be put into one line like you said. I tried the umask idea and for some reason "umask=0" didn't work like it should have. Oh well... :-)

Have a good one.

Hi.
I've met about the same problem and I found a way around it: by using a LiveCD (knoppix) i read the /etc/fstab it built and tried to copy that kind of lines.
From what I found, you should use "users" instead of "user" - that way you would allow any user to umount it (not only the user that mounted it).
Also, umask=000,rw and, as a suplementary option, I saw they use exec, so it would be like
/dev/fd0 /mnt/floppy auto noauto,users,exec,rw,umask=000 0 0
