Mount: not a directory WTF?!

johnnyblade · 10-22-2006, 12:49 AM

Whaddup peeps? In a nutshell, I just converted from Fedora Core 1 to Slackware 11 and even though I've only been using it for maybe six hours so far, I already like it better, anyway, whenever I try to mount my cd-rom or cd-rw drives it keeps giving me the same crap:

mount: block device /dev/hdc is write-protected, mounting read-only
mount: Not a directory

And then nothing. I'm not going to bother with the whole fstab bs for the moment, I'm trying to mount these drives manually. And I'm root when I try to mount them so I don't wanna hear anything about permissions. My cd-rw drive is on /dev/hdc and my cdrom is /dev/hdd when I try to use mount -t iso9660 /dev/hdc /mnt/cdrw it gives me the same errors. I manually created the /mnt/cdrw directory to mount my cds here and it keeps on giving the same error. I know it can't be the scsi emulation mucking it up because it does this with my cdrom too. Yes they are on the same ide channel, (i don't use scsi or sata, yet) these are run of the mill atapi drives. It's really pissing me off because all of my data is backed up on CD and I need it. I have no other OS on my system, it's just Slackware. So WTF is going on?

fstab is not that difficult and allows you to mount devices frequently without having to type the whole mount command again and again.

Try mounting with the "auto" option for filesystem.

Would you post the command you use to mount the device.
Also look at output of dmesg there might be a clue.

Try mounting in your $HOME directory also.
mkdir cdrom
mount -t iso9660 /dev/hdc cdrom

And you don't have any aliases like cdrom or cdrw do you?

Show us the output of:

Code:

# cat /etc/fstab

as well. And for lines like:

Code:

/dev/<somesthing> /<location> <item> <item> <nr> <nr>

Show us the output of:

Code:

# ls -ald /<location>; file /<location>

Okay here's the contents of /etc/fstab fresh from the konsole:

/dev/hda2 swap swap defaults 0 0
/dev/hda1 / reiserfs
/dev/hda3 /home reiserfs defaults 0 0
/dev/cdrw /mnt/cdrw auto noauto,owner,ro 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 defa

As you can see it's already set up for auto fs detection, and it gives me the same bs. this is the command I used just five seconds ago to mount the cd-rw as well as the ouput from that command:

root@darkstar:~# mount -t auto -o unhide /dev/hdc /mnt/cdrw
mount: block device /dev/hdc is write-protected, mounting read-only
mount: Not a directory

I've also tried this:

root@darkstar:~# mount -t iso9660 /dev/hdc /mnt/cdrom
mount: block device /dev/hdc is write-protected, mounting read-only
mount: Not a directory

and this:

root@darkstar:~# ls -ald /mnt/* ; file /mnt/*

See what I'm getting at? This doesn't make any sense at all, and here, just for the sake of being thorough:

I've already recompiled the kernel, (it was necesssary to get my mouse working) but prior to that I had the same troubles. I'd try with a 2.6 kernel but my 2.6 kernels are on, you guessed it, CD. And I don't have broadband so downloading one is out. i think whoever figures this one out should get a golden penguin award or something,

/bin/bash · 10-22-2006, 07:57 PM

Run dmesg after you get the error. You only need to post the last few lines of dmesg.
dmesg |tail

Also if you try to mount to a non-directory you get a different error:
# mount /dev/hdc file
mount: block device /dev/hdc is write-protected, mounting read-only
mount: mount point file is not a directory

That is a different error than you are getting.
mount: Not a directory

So your error is not from mounting to the wrong mount point.
