Problems with mount

stormrider_may · 07-19-2006, 10:27 PM

Hello,

I'm having a strange situation, when my cdrom is not mounted, i get those permissions:

drwxr-xr-x 2 root cdrom 48 2006-06-06 11:50 cdrom1

Then when i try the cdrom, permissions change to this...

drwx------ 5 400 401 4096 2003-10-05 16:41 cdrom1

What can i do to fix this????

Here is fstab

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
/dev/hda2 / reiserfs notail 0 1
/dev/hda1 /home/fernando/hd reiserfs defaults 0 2
/dev/hdc /media/cdrom0 iso9660 users,ro,noauto,noexec 0 0
/dev/hdd /media/cdrom1 iso9660 defaults,ro,user,noexec,noauto 0 0

thanks

Try this:

Code:

dev/hdd /media/cdrom1 iso9660 users,ro,user,exec,noauto 0 0

and post the results...

Same thing, the permissions/owner when i mount changes to:

Code:

drwx------ 5  400   401 4096 2003-10-05 16:41 cdrom1

Thanks for you answer.

How do you mount (exact command)? What output do you show us when you post the permissions, "ls -l"? Did you umount before you tried my suggestion?

stormrider_may · 07-20-2006, 07:30 AM

I'm pasting what i am exactly doing...

Code:

debian-fernando:/media# ls -l
total 0
lrwxrwxrwx 1 root cdrom  6 2006-06-06 11:50 cdrom -> cdrom0
drwxrwxrwx 2 root cdrom 48 2006-06-06 11:50 cdrom0
drwxr-xr-x 2 root cdrom 48 2006-06-06 11:50 cdrom1
debian-fernando:/media# mount /dev/hdd
debian-fernando:/media# ls -l
total 4
lrwxrwxrwx 1 root cdrom    6 2006-06-06 11:50 cdrom -> cdrom0
drwxrwxrwx 2 root cdrom   48 2006-06-06 11:50 cdrom0
drwx------ 5  400   401 4096 2003-10-05 16:41 cdrom1
debian-fernando:/media#

JZL240I-U · 07-20-2006, 07:46 AM

Oh. Assuming you made the change in/etc/fstab I suggested above, try

Code:

umount -a
mount -a

and check again...

stormrider_may · 07-20-2006, 09:04 AM

Here it is

Code:

debian-fernando:/home/fernando# umount -a
umount: /home/fernando/hd: device is busy
umount: /dev: device is busy
umount: /: device is busy

Why do you want to mount something which is already mounted, namely /dev/hdd? Well, if this is what you want, try

Code:

mount -o,remount /dev/hdd
{man mount on the syntax for the -o and remount flags,
I'm not sure whether I remember that correctly... }

i'm not trying to mount something that is already mounted, take a look:

Code:

debian-fernando:/media# umount -a
umount: /home/fernando/hd: device is busy
umount: /dev: device is busy
umount: /: device is busy
debian-fernando:/media# mount -a

JZL240I-U · 07-20-2006, 09:34 AM

Hm, yes you're right. Now, try it with "-o,remount" it should use the parameters from your fstab...

stormrider_may · 07-20-2006, 09:43 AM

same things...

Code:

debian-fernando:/media# mount -o,remount /dev/hdd
debian-fernando:/media# ls -l

JZL240I-U · 07-20-2006, 10:03 AM

Grrr. What happens when you issue a "chmod 755 /media/cdrom"?

I can't do this, because cdrom is mounted as a write-protected fs

stormrider_may · 07-20-2006, 03:44 PM

where can i set which user cdrom will be mounted as?

Huh? What's that got to do with another?

What is the error message, when you issue chmod?

In /etc/fstab. But you allow groups to mount (in my earlier post it was the group "users"), so if you want one single user to be able to mount, you create a group like "cdmounter" or some such and add the special user to this group. root is allowed to mount, too.
