[gentoo-user] Can't see /dev/hda1,2,3 but I know they exist...

I performed a bit of an update on my laptop a day or two ago, and after
reboot, I lost the ability to do anything with /dev/hda*. I currently have 0
swap space, and according to stat, ls etc, they don't exist. But, booting to
an install CD I burned for diagnostic purposes, it sees them just fine.
Also, and this is the strange part. It boots no problem, so the OS is able
to mount at least /dev/hda3, even though from the command line I'm not
seeing it. I'm probably missing something completely dead obvious (it's
after midnight here and all), and Google's turning up nothing, so if someone
could kindly slap me in the face with it, that'd be appreciated. Thanks
either way for whatever help comes my way.

How about /dev/sda1,2,3?

There is no /dev/sda*, either. First thing I checked.

As your root-filesystem does appear to be mounted, can you give use the result 
of the "mount" command to see how it identifies the root-filesystem?

I have seen harddrive naming schemes change between kernel versions. Eg. hda 
might end up being hdb or hdc,... (same with sd.....)

Alternatively, to avoid this, you could use drive-labels and configure 
/etc/fstab with these labels rather then the drive-items.

Can you also show us the dmesg-output to see if the drives are actually 
identified?
If "udev" is not running correctly, the device-nodes might not be created 
automatically.

Hello. Please quote correctly when you reply, like everybody else.

You can see the partitions listed in the /proc/partitions file.

Kernel versions of native install and Live CD?

I susupect Hung's suggestion may be the answer.  AFAIK grub is boot
strapping before the kernel, and so the devices can be named different
from BIOS and the install.  I had a similar strange problem where I
needed symlinks for hd devices to sd devices or vice versa with an
older kernel and newer hardware (and I think some BIOS tweaks).  [I'm
not recommending people to symlink devices, since that seems like a
bad way to do things, but I'm willing to be stupid for myself in cases
of need.]

Kernel versions of native install and Live CD?

Native install is running 2.6.29. Live CD is running I'm not certain which
version kernel. It's the most recent ISO of the X86 CD however, so I imagine
later than that.

See the "When is a disk not a disk" thread a few days ago. I guess this is 
the same problem:

That seems to have been it. Testdisk did indeed write a new partition 
table, minus one of the partitions which it insisted on deleting so I 
suppose something was wrong with it.

The first thing that jumps to my mind is you have an older initrd that
has your HD drivers in it (such as ATA), but the newer kernel you've
probably just built (is that what you mean by "a bit of an update"?)
doesn't.

Check for an initrd, and tell us what "a bit of an update" means :)  You
could also compare config files between your rescue CD and your system,
if you can find it!

You could see your HDD because the boot CD have enabled all drivers.
Could you double check if you have configured the kernel for your HDD
correctly?

The kernel was not updated or changed since the laptop's last fully
successful boot. And, at that time, it was configured to acknowledge my HDD.

thanks for bottom posting, but I'm having a hard time differentiating
between your post and the one your responding to, because they're on the
same level.  I guess you're using Outlook because you can't boot
properly?  In Outlook you can tell it to prepend the standard "> "
before the original message in the menu somewhere.

So back to your problem - you can boot but just how far?  Can you log
into X?  What were the updates you applied?  (Please list them all).
What boot messages do you see?  How do you log in?

Type `fdisk -l` and post the output.

thanks,

Copy the live cd kernel to your machine and make it an option in grub
and try booting that.  Then at least you can stop chrooting and
optical mounting.  This will give us some information on if it is a
kernel problem or not.  Make sure to make modules_install

If it's the kernel, check out kccmp to compare the kernel options
between Live CD and the machine's kernel configuration after you dig
up the configuration for the kernel on the Live CD.

Other people are mentioning udev, and I wonder about this, too.
Either before or after you check the kernel (whichever you decide is
easier or seems better to you), can you chroot and rebuild udev
through portage and also run a revdep-rebuild please?  You said you
updated, but it is not clear to me that the full update was proper.
If you don't have revdep-rebuild, emerge the gentoolkit in the portage
tree to get it, and check out the documentation to see what else it
includes!

Hi,
  I just had to restart my computer (power issues :( ) in the middle of
an update (well, it was more like 'just before the end';) and after
restart I have the same problem as you, no /dev/sd[ab]* files...

My first guess was that I rebooted without updating the config files, so
I ran etc-update (there were some udev config files as well as init
script) and rebooted, but that didn't help.

It is certainly not a problem with drivers not being in kernel, as the
kernel sees the disks and partitions (see below), so I just run

tail  -n +3 /proc/partitions | while read maj min size name  ; do  mknod /dev/$name b $maj $min ;  done
/etc/init.d/localmount pause; /etc/init.d/localmount start

to get everything mounted again...

That means it will have to be an  udev (or even openrc) problem.
The last update of udev did in fact say this:

 * Checking for suitable kernel configuration options...
 *   CONFIG_SYSFS_DEPRECATED:    should not be set. But it is.
 *   CONFIG_SYSFS_DEPRECATED_V2:         should not be set. But it is.
 *   CONFIG_IDE:         should not be set. But it is.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.
 * 
 * udev-151 does not support Linux kernel before version 2.6.25!
 * For a reliable udev, use at least kernel 2.6.27

 * Your kernel version (2.6.28-gentoo-r2) is new enough to run udev-151 reliably.

I didn't want to mess with the kernel right now, but I gues that's the
first thing to try...
I'll report when I rebuild & reboot...

yoyo

yop, that was it

though you wrote about /dev/hda*, which means you should be a bit more
carefull if you used the IDE drivers (under ATA/ATAPI/.... support,
thats the "CONFIG_IDE" option) and disabled the CONFIG_IDE options, you
have to enable it under
Serial ATA (prod) and Parallel ATA (experimental) drivers (CONFIG_ATA)
and also your device might get renamed to sd* instead of hd* (I don't
know, I have only a cdrom, that becomes sr0 ;)

But I think that the real problem was with those SYSFS_DEPRECATED
options, so you might be able to get things working with just disabling
those and leaving IDE as it was...

btw, I found this bug afterwards:

yep, switch from CONFIG_IDE to Parallel ATA.  And the drives will be
changed from hda to sda, so be prepared with a boot disk to change
fstab.
