[gentoo-user] mounting cdrom during boot

[gentoo-user] mounting cdrom during boot

[-- Attachment #1: Type: text/plain, Size: 791 bytes --]

Everytime I boot my system I see this message:
==========================================
/dev/cdrom: open failed: No medium found
==========================================

Everytime I shut down my system I see these (those two lines were repeated 23 
times during last shutdown):
==========================================
/dev/cdrom: open failed: No medium found
Attempt to close device: '/dev/cdrom' which is not open.
/dev/cdrom: open failed: No medium found
Attempt to close device: '/dev/cdrom' which is not open.
...
==========================================

I do not have a cd in the drive. Earlier /dev/cdrom was in /etc/fstab with the 
noauto option. After I discovered this I tried removing it from /etc/fstab. 
But no change. Any ideas?

Are you using LVM?

Sure. So it's because of this?

========================
# grep ^\ *filter /etc/lvm/lvm.conf
    filter = [ "a/.*/" ]
========================

Thanks for the pointer. I forgot to change that when I reinstalled after my 
old harddrive was replaced. :)

Yup. Remove the cdrom and then:

# lvchange -a y

Yes, you need to comment this line and uncomment the cdrom line. Or you
can use a filter line that only permits specified devices, which also
stops LVM scanning any memory sticks etc (unless you want LVM on a memory
stick :)

Well, I'm not using LVM and I'm getting the same messages (unless I
have a CD  in the drive).

I have changed it to this:

========================
# grep ^\ *filter /etc/lvm/lvm.conf
    filter = [ "a|^/dev/hda|", "r/.*/" ]
========================

My cdrom drive is /dev/hdc. But this has not changed anything. I still get 
those messages. :(

Try

filter = [ "a|^/dev/hda|", "r|.*|" ]

Just a guess, is it one of those hald "auto mount everything I put anywhere near the computer so I act like windows" things?

Thank you for your reply. Like I said in the original post it already 
contained noauto in /etc/fstab. In fact it was identical to the line you are 
showing. As that didn't help I also tried outcommenting that line 
in /etc/fstab. That didn't change anything either. :(

PS. Please in the future post your response below that which you are 
responding to.

I think it is related to lvm2 somehow because of this:

==========================================
# vgchange -a y
  /dev/cdrom: open failed: No medium found
  Attempt to close device '/dev/cdrom' which is not open.
  7 logical volume(s) in volume group "vg" now active
==========================================

The hal use flag is disabled and hal, pmount and autorun are not installed.

Are you sure that's the only filter command in the file? Only the first
one is used.

It wouldn't hurt to an "r|/dev/cdrom|" to the filter.

Did you run vgscan after editing the file?

    # Remember to run vgscan after you change this parameter to ensure 
    # that the cache file gets regenerated (see below).

Nope. I missed that part. I /think/ I did reboot though but that didn't seem 
to fix it. Anyway running vgscan seems to have fixed it. Thanks.
