[gentoo-user] mount cdrom: No buffer space available

[gentoo-user] mount cdrom: No buffer space available

[Thufir]

I'm going by <http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?
part=1&chap=8> to mount the cdrom and cdrw drives, but it's failing.

There are two optical drives:  a CD-ROM and a CD-R/W; both drives work 
physically.

When I enter "mount /mnt/cdrom1" or "mount /mnt/cdrw1" then I hear a 
drive spin before it fails, but "mount /dev/cdrom" doesn't cause any 
noise.  They all fail, error messages:

A Google seems to suggest that "mount: No buffer space available" is  
commonly returned when the device is already mounted.

The manpage for `mount` indicates that `mount -a` will mount all  
devices listed in /etc/fstab, so your output suggests to me that the  
CD drives are mounted when you issue this command - no wonder they  
fail when you try to mount them again separately!

I don't use optical drives very much under Linux, so please forgive  
me if I'm mistaken. I'd think that `df` would show the mount status  
of optical drives, so IMO it'd be useful to post the output of `mount  
-va && df && mount -v /mnt/cdrom`

Oh, I wasn't finding that or didn't know how to interpret it.

Yes, I concur with everything above.  However, I guess I left out the 
fact that there's a disc in each drive; the discs are readable.

Possibly, but I think this is unlikely.  I have seen the 'already
mounted' error many times but never this buffer error.

I also found (with Google) one forum posting where it was stated that the 
cause was a bad, self-burned disk in the drive. When the poster changed the 
disk, the problem disapeared.

Who knows?  If the mounting process does a whole bunch of stuff before
allocating buffer space or dying on that error, it's difficult to say
what's going on ... without looking at the code.

In this case, the discs are fine, as are the drives.  The drives mount 
fine in Fedora and read these particular discs fine (music CD's).

What other things effect mounting devices? can I test the /dev/ 
configuration?  how about mtab?  Just shots in the dark...

You don't mount audio CDs.

Not to listen to them, or to get any sort of valuable information off
them.  But can't you mount them?  I vaguely remember being confused
when the files (TOC) i copied off a music CD wouldn't play by
themselves...

There is no need to do so. However, a fuse based filesystem for mounting 
audio CDs exists, see http://castet.matthieu.free.fr/cddfs/.

Oh, thank you all for your input -- I've been a bit obsessed with rails 
and let this go to the back burner a bit.

However, I did notice that when I click on "CDROM" from nautilus there's 
a message about HAL; again, though, it cannot be a hardware issue as 
these particular discs and drives work in another distro on the same 
machine.

On boot, and I think shutdown, there are messages about failing to access 
the CDROM -- this is post POST and after GRUB -- I think; maybe it's on 
shutdown only.

I believe it to be a driver issue (HAL is a hardware driver?  Hardware 
Abstraction Layer?  But isn't it more BIOS than OS?).  I'll double check 
things with some data discs on the other distro in the next few days and 
do some more googling (and wikipedia-ing).

If this sheds any light:

I think it's more on shutdown that I notice lotsa weird messages about 
the cdrom drive(s) since futzing with /etc/fstab.

If the discs and drives work on the same machine with a different distro,
then I agree, the hardware should work.

Also, as the /dev/ entries exist and it doesn't complain about that, the
drives are probably detected correctly.

Can you also check with datadiscs on the Gentoo installation?
I agree with the others that audio-discs are generally not mountable.
The FUSE-driver for Audio-discs might be installed on your other distro
(Redhat?), but is not installed by default with Gentoo.

<Snipped dmesg-output>

When I do the above command, it only shows me the cd/dvd writer, not the
cdrom drive.
Can you post the full output of "dmesg" after you booted the system?

Can you also give us the contents of your "/etc/fstab" file?

Haven't followed up all of this thread, but it may well be a clash between 
hald/dbus trying to control your media devices and your fstab.  Entries in 
the latter are only applicable if you want to be mounting such devices 
manually.
