[gentoo-user] Again - problem on installing Gentoo

[gentoo-user] Again - problem on installing Gentoo

[Stephen Liu]

Hi folks,

Have another round installing Gentoo, running
"install-amd64_minimal-2006.1".  Still encountered the same problem
apart from that of Internet connection.  Installation went through
without difficulty.  Grub started but ending at "Error 15 : File not
found".

I installed grub manually with;
# cat << EOF | grub
> root (hd0,0)
> setup (hd0)
> EOF
...... (hd0,0)/boot/grub/stage2/boot/grub/menu.lst...succeeded.

Kernel image has to be copied manually;
# cp arch/x86_64/boot/bzImage /boot/linux-2.6.17-gentoo-r5

# ls -al /boot/
.keep
boot -> .
grub
linux-2.6.17-gentoo-r5
loar+found
* end *

What is ".keep" there ?

/boot/grub/grub.conf
...
....
kernel (hd0,0)/boot/kernel-2.6.17/gentoo-r7 root=/dev/hda2
* end *

I still could not resolve re-entering chroot environment unable to find
"env-update, emerge, /src/, /modules/".  I wonder whether I was
following the right book.  It seems to me installing Gentoo even more
difficult than installing LFS and BLFS.

Advice would be appreciated.  TIA

Hi,

Are you sure about 'kernel (hd0,0)/boot/kernel-2.6.17/gentoo-r7
root=/dev/hda2'
Shouldn't it be 'kernel (hd0,0)/boot/kernel-2.6.17-gentoo-r7 root=/dev/hda2'
instead ?

Just rechecked it.  It is;
'kernel (hd0,0)/boot/kernel-2.6.17-gentoo-r7 root=/dev/hda2'

Sorry it was my typing mistake on my posting.

= wrong kernel name

try: 'kernel (hd0,0)/boot/linux-2.6.17-gentoo-r5 root=/dev/hda2'

On a side note:
You asked about the "boot -> ." symlink in your previous thread, this is a 
convenience thing for users like you.

You have a seperate /boot partition /dev/hda1 with the kernel.
But you tell grub the kernel is at "(hd0,0)/boot/<kernel>"
This maps to /dev/hda1/boot/<kernel>

By linking "boot -> ." grub can still find the kernel even though the config 
is wrong.

During installation after chroot, I ran;

# ls -l /usr/src/linux
lrwxrwxrwx  1  root  root ...... /usr/src/linux ->
linux-2.6.17-gentoo-r7

I used it as kernel version.

/usr/src contains the source to the kernel (as you'd expect form the
name). The actual kernels live in /boot, this is the version that must
match.

As was previously pointed out, if you use "make install" to install your
kernel, the correct files are copied to the correct places, and symlinks
are set up so you don't need to mess with your bootloader config.

Hi Neil,

Gentoo started booting after changing following line;
kernel (hd0,0)/boot/kernel-2.6.17-gentoo-r7  root=/dev/hda2
to
kernel (hd0,0)/boot/linux-2.6.17-gentoo-r7  root=/dev/hda2

But still having following problems;


1)
Engine: Unable to open the engine block file /var/lock/evms-engine :
Read only filesystem.  The engine is not protected against other
instances of the Engine being opened at the same time.  Error returned
from evms_commit_changes ( ) : No such device [!!]


2)
Loading module 3c59x ....
Failed to load 3c59x  [!!]


3)
All
/dev/vg/usr
/dev/vg/home
/dev/vg/opt
/dev/vg/var
/dev/vg/tmp

have same problem as listed follow;
e2fsck: No such file or directory which trying to open /dev/vg/usr. 
The super block could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else).  There the
superblock is corrupt, and your might trying e2fsck with an alternative
superblock :
e2fsck -b 8193

# e2fsck -b 8193 /dev/vg/usr
fsck.ext3: No such file or directory while trying to open /dev/vg/usr

Please advise how to fix them.  TIA

Hi,

Do you follow the installation guide from gentoo.org? I mean, do you use a
"standard" scheme?

Hi Jean-Marc,

> Do you follow the installation guide from gentoo.org? 

There are several documents on Gentoo website.  I followed 2 documents:

Partitioning HD with LVM
Gentoo LVM2 installation
http://www.gentoo.org/doc/en/lvm2.xml

Installation
Gentoo Linux AMD64 Handbook
http://www.gentoo.org/doc/en/handbook/handbook-amd64.xml


> I mean, do you use a

I made some adjustment for my case.  I did not emerge LVM2.  

If fail again.  I'll run a final test according their HD config (w/o
slave), not running LVM.

Re: [gentoo-user] Re: Again - problem on installing Gentoo (Gentoo started)

[Stephen Liu]

Hi folks,

Fruther to my late posting, now Gentoo started finally, but still
having problem on mounting Logcial Volumes;
/dev/vg/usr
/dev/vg/home
etc.

"localhost login" started.  Root login was possble.


/etc/fstab now looks like as follow:
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
proc /newroot/proc proc rw,nodiratime 0 0
sysfs /newroot/sys sysfs rw 0 0
udev /newroot/dev tmpfs rw,nosuid 0 0
devpts /newroot/dev/pts devpts rw 0 0
cachedir /newroot/mnt/livecd/lib64/splash/cache tmpfs rw 0 0
tmpfs /newroot/mnt/livecd/lib64/splash/tmp tmpfs rw 0 0
tmpfs /newroot/mnt/livecd/lib64/firmware tmpfs rw 0 0
tmpfs /newroot/mnt/livecd/usr/portage tmpfs rw 0 0
usbfs /newroot/proc/bus/usb usbfs rw 0 0
/dev/hda2 / ext3 rw,data=ordered 0 0
/dev/hda1 /boot ext2 rw,nogrpid 0 0
/dev/vg/usr /usr ext3 rw,data=ordered 0 0
/dev/vg/home /home ext3 rw,data=ordered 0 0
/dev/vg/var /var ext3 rw,data=ordered 0 0
/dev/vg/opt /opt ext3 rw,data=ordered 0 0
/dev/vg/tmp /tmp ext3 rw,data=ordered 0 0
none /proc proc rw,nodiratime 0 0
udev /dev tmpfs rw,nosuid 0 0
* end *


"tmpfs /newroot" not created during booting.

I think following warning is critical;
device-mapper : dm-linear : Device lookup failed
device-mapper : error adding target to table

Any advice???  TIA

Your previous mail stated that you did not emerge lvm2. 
However, /dev/vg/usr IS a logical volume so it will never work 
until you install the lvm2 software.

Look Stephen, throughout this thread several people have asked 
you if you followed the relevant howtos and your replies were 
mostly, um, evasive. The errors you are making are elementary - 
wrong file names, trying to use a facility that has not been 
installed, etc. So I earnestly recommend you go back to the 
howto on the wiki, and follow the instructions EXACTLY, without 
trying to tweak stuff and be different. Once it's working, then 
you can tweak it.

He has EVMS installed, he doesn't need lvm2 tools.

My problem is LV not being activated on booting so all devices such
/dev/vg/usr, home, opt, etc. can't not been mounted.  At time of
installation ;
# vgchange -a y 
must be run to activate LV.

I'm now looking around where ("/rc.d/"  ?) I have to add this command.

I tried creating /tmp/newroot, /tmp/newroot/mnt, etc.in anticipating
mounting LV.  But found it did not work.

Actually Gentoo started but the above devices unable to mount making
some files can't be found.  Other problem are of minor matters.

In the past I have been playing around on FC5 and Ubuntu 6.06

My problem is LV not being activated on booting so all devices such
/dev/vg/usr, home, opt, etc. can't not been mounted.  At time of
installation ;
# vgchange -a y
must be run to activate LV.

I'm now looking around where ("/rc.d/"  ?) I have to add this command.

I tried creating /tmp/newroot, /tmp/newroot/mnt, etc.in anticipating
mounting LV.  But found it did not work.

Actually Gentoo started but the above devices unable to mount making
some files can't be found.  Other problem are of minor matters.

In the past I have been playing around on FC5 and Ubuntu 6.06
partitioning HD with LVM on command lines but never work.  I was
compelled using GUI to get it done.  Then it worked without problem.  I
don't know its reason.

Sorry if this sounds harsh but if it works from the GUI but not from the
commandline then the problem exists between keyboard and chair: you're not
typing in the commands properly. Computers are stupid. They need to be told
EXACTLY what to do; spelling mistakes just don't cut it. FWIW the other day
I need to do some "resurrection" work involving LVM and it would have taken
a quarter of the time if I'd just been more careful ;-)

I tried dozen times on Ubuntu unable to activate LV.  Sorry I don't
think it was keyboard problem.  I also followd their installation book.
 The folks on their mailing list tried to assist me without result. 
Problem was unknown.

Did you compile dm into the kernel (or: Is the dm-mod modules loaded?)?

At time of installation I ran;
# modprobe dm-mod
No printout

Afterwards I found it for "Loading the LVM2 module".  I ran LVM not
LVM2 so I did not care it further.

I can re-run the above command again starting the 
"install-amd64-minimal-2006.1".  It is before "chroot".  If after
"chroot" I have to wipe out the HD and re-work from the beginning.

I think following warning is a major problem;
device-mapper : dm-linear : Device lookup failed
device-mapper : error adding target to table

How to check whether EMVS is working?  Tks

There is no LVM2 module.

From the EVMS FAQ:

"Q.  I'm running on a 2.6 kernel and some or all of my volumes fail to get 
activated. The volumes don't show up in the /dev/evms/ directory and I get 
the following errors in my kernel log: 
device-mapper: dm-linear: Device lookup failed
device-mapper: error adding target to table

A.  You probably need to apply the bd-claim patch to your kernel. See 
http://evms.sf.net/install/kernel.html#bdclaim for more details about this 
patch and other possible options."

The problem is that beginning with kernel 2.6 it is no longer allowed to 
talk to devices via different paths (i.e. /dev/hda1 and /dev/evms/hda1). So 
evms_activate (or: the device-mapper) will have problems creating a mapping 
when the device is allready used via a different path. However, from the 
other mails in this thread, I don't see where this is happening.

Are you using both lvm2 tools _and_ EVMS? Then it is clear that the latter 
will fail.

Sorry, it's on the book:
http://www.gentoo.org/doc/en/lvm2.xml
Code Listing 2.1: Loading the LVM2 module
# modprobe dm-mod

I haven't installed LVM2 intentionally.  Neither I selected LVM2 module
in kernel Device Drivers, IIRC, nor I ran "etc-update".  I'll start
Gentoo later to check it again.

Others noted with tks

Then the book is wrong, or at least misleading. The header should then 
be: "Loading the Device Mapper module", because this is what the command 
does.

Yes you have, otherwise it wouldn't be there.

Again, how comes it exists, if you didn't select it (assuming you've not 
used genkernel)?

I don't get the point about etc-update?

Starting Gentoo and login as root

To fix "Volume activation"
device-mapper: dm-linear: Device lookup failed
device-mapper: error adding target to table

Edited "/etc/evms.config"
under "Sysfs_device
added "exclude = [hda]

Now problem GONE.


The remaining mounting problem are;
mount : mount special device /dev/vg/usr does not exist
mount : mount special device /dev/vg/home does not exist
mount : mount special device /dev/vg/opt does not exist
mount : mount special device /dev/vg/var does not exist
mount : mount special device /dev/vg/tmp does not exist

re-ran
# modprobe de-mod
FATAL: Module dm-mod not found.

Any suggestion?  TIA

Clearly, you did not follow the guide !
Clearly this is yet another mistake you made yourself !
Clearly we *cannot* help you if you randomly follow parts of guides !

If you dont know *exactly* what you are doing you should follow the guide to 
the letter !

I suggest you skip LVM and stick to the official installation guide.
I suggest you take small steps and learn in small increments cause you're in 
way over your head right now.
