Re: Gentoo failed to start

Hi Jarry and folks,

Tks for your advice.

Booting with a LiveCD:
My problem booting with Knoppix5 is it does not support LVM, vgscan,
vgchange, etc. not available.  I can only boot with "Gentoo
install-amd64-minimal-2006.0"

After activating lv, mounting all devices, etc., coming to;
# mount -t proc none /mnt/gentoo/proc
# mount -o bind /dev /mnt/gentoo/dev
# env-update
-/bin/bash:env-update:command not found.

It did happen in my previous rounds.  Other command such as "emerge"
also found missing compelling me to wipe out the HD and to start again.
 Any suggestion.  TIA

Another problem I forgot to mention in my previous posting is;
/lib/modules
was missing

# ls -al /lib | grep modules
did not find it.

Problem about switching consoles.  After "chroot" I can't read online
manual.  Therefore I have to press [Ctrl]+[Alt]+F2 switching to another
console.  (I suppose the working console is [Ctrl]+[Alt]+F4).  But
after switching back to the working console all the work disappeared. 
It did happen occassionally but not always.  Any advice?  TIA.

Because it's confusing.

You need to chroot to /mnt/gentoo before running etc-update:

# mount -bind /dev /mnt/gentoo/dev
# cd /mnt/gentoo ; chroot ./ ./bin/bash
# etc-update

Also chroot needed here?

I think you've gotten confused by which console you are working on.
Normally the live CD starts several consoles (6?), that are accessible
on Alt+F1 through Alt+F6.  (The Ctrl+Alt combination is only needed
when switching from X to a console).  So most likely, you were working
on tty1 (Alt+F1).

Hi Richard,

Yes I did.  Sorry for not listing them on my previous posting.  Steps
taken previously as follows;

# cd /mnt/gentoo
# mount -t proc none /mnt/gentoo/proc
# mount -o bind /dev/mnt/gentoo/dev
# chroot /mnt/gentoo /bin/bash
# env-update
-/bin/bash:env-update:command not found.

other commands also not found.

If I start again wiping out the complete HD, following the steps on the
handbook.  Then it worked seamlessly.

# env-update
>> Regenerating /etc/ld.so.cache....

I can't resolve if after exiting chroot and re-enter chroot, commands
will disappear.  I tried many times in my previous rounds.

I'm sure on my previous rounds, [Ctrl+Alt+F4] switching back to the
working console.  Sometimes all work were there.  Another time they
were lost.

I'll try your advice "Alt+F1" next time.  Tks

Re: Gentoo failed to start

Hi Richard and folks,

Further to my late posting, tried again still failed.  Steps performed
as follows;

After activating lv, vg, mounting device, partitions, etc.;

# cd /mnt/gentoo
# mount -t proc none /mnt/gentoo/proc
# mount -o bind /dev /mnt/gentoo/dev
# chroot ./ ./bin/bash
All w/o complaint

# env-update
-/bin/bash:env-update:command not found

ignoring the above complaint and continued:
# source /etc/profile
# export PS1="(chroot) $PS1"
both w/o complaint

Edited /etc/fstab as follows;
/dev/hda1  /boot ext2  defaults,noatime  1 2
/dev/hda2  /  ext3  noatime  0 1
/dev/hda3  /  swap  sw  0 0

/dev/vg/usr  /usr  ext3  noatime  0 1
/dev/vg/home  /home  ext3  noatime  0 1
/dev/vg/opt  /opt  ext3  noatime  0 1
/dev/vg/var  /var  ext3  noatime  0 1
/dev/vg/tmp  /tmp  ext3  noatime  0 1

/proc  proc  default  0 0
/dev/shm  tmpfs  nodev,nosuid,noexec  0 0

/dev/cdrom  /mnt/cdrom  auto  noauto,user  0 0
/dev/cdrom1  /mnt/cdwriter  auto  noauto,user  0 0
* end *

Ran
# grep -v rootfs /proc/mounts > /etc/fstab
No complaint

Exited chroot and umounted all devices and partitions.  Rebooted PC.

Still failed, only a black screen with 2 "!" scatering on it.  Neither
"grub>" displayed.

Tks

Does this filesystem contain a grub directory with stage2, menu.lst
(or grub.conf), etc?  What does grub/{menu.lst,grub.conf} contain?

> # grep -v rootfs /proc/mounts > /etc/fstab

Um...you mean ">/etc/mtab", right?  Otherwise your fstab is going to
contain things that are not really necessary, like usbfs and sysfs
filesystems....

Anyway, this step is really not even necessary even with mtab, as
Gentoo will fix it when you boot.

Did you install grub?  If so, did you use grub-install or my previous
instructions?  What output did you get from that?  I guess try
re-installing grub.

another upgrading to gcc 4.x issue

During 'emerge -e system' I have got emerge errors for two
packages (sys-libs/db and sys-libs/pam). At both cases an
error is something like this:

...
checking for a BSD-compatible install... /bin/install -c
checking for i686-pc-linux-gnu-cc... i686-pc-linux-gnu-cc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
...

All other 120 packages were emerged without problems.
Where to dig in?

Re: Gentoo failed to start

Hi Richard,

After entering chroot environment re-installed grub;

# cat << EOF | grub
> root (hd0,0)
> setup (hd0)
EOF

Running "install /boot/grub/stage1 (hd0) (hd0)1+16 p
(hd0,0)/boot/grub/stage2 /boot/grub/menu.lst"... succeeded

Exited chroot and umount everythings.  Rebooted PC.

Grub started but ending at;
root (hd0,0)
Filesystem type is ext2fs  Partition type 0x83
kernel (hd0,0)/boot/kernel-2.6.17-gentoo-r7 root=/dev/hda2
Error 15:File not found.
Press any key to contiue

Restarted PC and entered chroot environment again.  Found
/usr/src/linux file missing.  It should be symbolic-linked to -->
linux-2.6.17-gentoo-r7

Failed to re-run 
# USE="-doc symlink" emerge gentoo-sources
because "emerge" command not found.

Further discovery: new /etc/fstab
tmpfs /newroot tmpfs rw 0 0
/dev/hdd /newroot/mnt/cdrom iso9660 ro 0 0
/dev/loop/0 /newroot/mnt/livecd squashfs ro 0 0

/dev/vg/tmp /tmp ext3 rw,data=ordered 0 0
none /proc proc rw,nodiratime 0 0

* end *

Would it be the result of previously running;
# grep -v rootfs /proc/mounts > /etc/fstab

Deleted /var/lib/portage/config

I accidentally deleted /var/lib (I meant to delete /var/lib/mysql).
The only damage seems to be the deletion of /var/lib/portage/config
and /var/lib/portage/mysql

I'm not worried about world, I can easiliy fix that over time by
running emerge -p --depclean and adding world entries. There are
probably only about 10 packages anyways because this is a mythtv box.

But what is config all about? On my other machine it looks like the
file contains a bunch of hashes for config files in /etc/. Are these
used to quickly see if a file in /etc/ is different or does it just do
a diff?
