Grub2: os-prober problem

English Install/Boot/Login
1

Yesterday I installed openSUSE 12.2 kernel update from
config-3.4.11-2.16-desktop to 3.4.28-2.20-desktop. All went well,
rebuilt Nvidia module also. I tried several fixes in bug report on
Bugzilla. No help. They did show the os-prober did not run. I remember
some threads on mailing lists and formums about this problem Could not
find them. Supposed to have been fixed in 12.2.

Is this a regression in the new kernel version? Can I copy the old
submenu from the backup of /etc/grub.d/30_os-prober to new version of
/etc/grub.d/30_os-prober? Will it get wiped out each time I boot?

Is there another fix? Can I create a chain link to 12.1 and would I
put that in the custom section of grub.d?

[Disk Config]
sda → openSUSE with both kernels mentioned above. Active kernel is
3.4.28.
sdb → openSUSE 12.1
sdc → Not Used
sdd → 100GB Win Partition and 400 GB Backup for 12.2

And what is the problem? You never described it.

Sorry about that. As noted in 1st paragraph 4th line os-prober did not
run.

I agree its not clear on the problem. The problem is that the grub2 does
not detect the OS on sdb (openSUSE 12.1).

Notice there is no code between the comments.

Grub.cfg the openSUSE 12.1 is shown.

I’ve posted the current grub.cfg file at:

<http://paste.opensuse.org/59530840>

Here’s the current /etc/grub.d/30_os_prober section.
CODE

Notice ### BEGIN /etc/grub.d/30_os-prober ###

END /etc/grub.d/30_os-prober

/CODE

I have posted the old grub.cfg /etc/grub.d/30_os-prober section at:

CODE

Hope this answers your question. I will provide anything else you need.

It’s impossible to answer without seeing actual os-prober run logs, but one immediate idea is - if filesystem (I suppose, you have ext4 for 12.1) was not cleanly unmounted, os-prober cannot mount it to probe for operating system. Try to manually mount 12.1 root partition (mount point does not matter) and run os-prober. Does it detect it now?

5

Speculating,
It’s not entirely clear(to me at least) that you are really using GRUB or GRUB2 as the primary bootloader, and it may be that something changed that is not loading sdb early enough for the os-prober to see the disk. Note that you need to be looking at the <first> bootloader in your chain first, then the next, then next (etc). I can’t guess what order and what entries are in each bootloader, you’ve posted only a GRUB2 bootloader which may or may not be relevant.

Also, since this is a multi-boot, I wouldn’t know if simply doing a repair of some sort would fix the problem. If it’s merely a timing issue sdb is mounted by the time the boot menu appears) and you have a copy of your old grub.cfg, simply replacing new with old might work. But, that assumes a lot that’s not clear in your post.

yes my file system is exit4.

Where are the os-prober run logs located? Searched var/log and /boot. No
Logs. Do I need to turn them on somewhere?

Can I mount the 12.1 root from 12.2? I cannot get to the 12.1 diskexcept
from dolphin (12.2), Doesn’t that mean it is mounted correctly?

Thanks for your help!

It is using syslog, so they are in /var/log/messages. They are not always prefixed with os-prober, so makes sense to record the last message in /var/log/messages, run os-prober and paste to SUSE Paste everything from the recorded message onward. You can simply run os-prober standalone, no need to use grub2-mkconfig.

Is your openSUSE 12.1 on /dev/sdb5 or /dev/sdb6?

Got it Working!!
Not sure what fixed it but it’s fix I thing. Steps I went thru using
jcmcdaniels Grub2 Command Scripts:

  1. Ran /etc/grub.d/30_0s-prober (See http://susepaste.org/52294112)
  2. Ran update grub.cfg menu
  3. Displayed grub.cfg using grub.cfg editor
  4. Ran update /etc/default/grub
    got mmessage that item 4 has 644 permissions should be 755,
    continued.
  5. Restarted the computer and the grub2 menu came up with correct
    menu items.
  6. Rebooted computer, menu still good.

Only thing I noticed is /etc/default/grub now has <xxxx(has user
name)>:users as owner:group and 644 for permissions. old version has
root:root, permissions 644.

Which is correct, I would guess root:root but it was not working before
the above steps.

Any comments?

According to log you provided, os-prober correctly detected openSUSE 12.2 with root in /dev/sdb3. So it is still not clear what was the problem.

I don’t know what was wrong either. Once I ran os-prober stand alone,
and then updated the grub.cfg all is working well.

I going to replace 12.1 with 12.3 RC1 as soon as I get to it. May be
after I publish my Lions Club bulletin next week, cannot afford to not
get it out on time, Maybe RC2 by then.

Will see what happens. Thanks for all your help on this.

os-prober runs much smoother with rc1 and it automatically installed grub2-efi and added windows 8 to the boot menu

Good to know. I have EFI disabled in the BIOS on this system. As for
Windows 8 or any other MS product I do not use them. I have XP on
VirtualBox but have not used it in the last year as my motherboard does
not support 64 bit vitualization. When I get new motherboard I’ll see if
I will use it.

thanks for the information.

I’m still have strange problem with this;
On 2/13/2013 I got the os-prober to see the 12.3 install, then I did an
update (Using YaST) of 12.2 and this wiped out the section of the grub2
menu relating to 12.2. Stayed that way, even though I tried running os-
prober.

Today I did some updates again to 12.2. When i rebooted the menu had
links to os 12.3. The main lin started a boot, had error message:


[FAILED] failed to start Console System Start Up Logging
See ' console-kit-log-system-start.service' for details

it proceeded to al last visible message of:


Started cleanup of temporary directories

waited approx. 35 minutes and the did ALT/Control/Delete and it tried
again, got to same spot. Noticed the next message after the ALT/CTL/Del
Command was deactivating swap about five time.

Is it possible 12.2 is keep 12.3 from proceeding?

In conparing the menu entries on 12.3 to 12.2.Looking at the menu on
12.2, the 12.2 menu entries all look good. The entries entered by os-
prober for openSUSE 12.3 and the entry in advanced seem to boot to the
same spot and hang (see comments in paragraphs above (todays message).
The entry that should say recovery mode doesn’t. if you boot that entry
I get error message:


Invalid Magic Number

What is the magic number, who gererates it?

After this I tried the livecd and it boot into 12.3 OK. It is a little
slow.

Any Ideas what to check next or try.?

Thanks I really appreciate everyone who has responded.

So I am also noticing now the fact that Grub2 is no longer picking up my Windows install either or my EFI install on a separate hard drive. I have seen this on two PC’s with Windows dual boot. When I update grub2, this is the only added message I see:

Feb 27 18:40:32 LINUXMASTER sudo:    james : TTY=pts/4 ; PWD=/home/james ; USER=root ; COMMAND=/usr/sbin/grub2-mkconfig --output=/boot/grub2/grub.cfg

When I go and look at when Grub2 says it was last updated, it says: ** grub2-2.00-1.23.1 Mon 07 Jan 2013 05:15:31 PM CST**

Which is earlier than I would have guessed the problem began.

Thank You,

Not sure what I did to get it to work, except try running 30_os-prober
and update the grub2 grub.cfg file several times on 12.2. Then
experienced problem with hang in booting 12.3.

Finally I installed 12.3 RC2 from DVD RW and was able to boot 12.3.
Grub.cfg only saw the 12.3 options. Ran 30_os-prober, it detected my Two
12.2 versions plus 12.3. updated grub.cfg using grub2cmd script. All
working fine now.

12.3 appears good so far.

I now have sda - 12.2
sdb - 12.3 RC2

Have noticed on 12.2 so far after 2 updates to grub2-branding-opensuse
that the devices detected on 12.2 are lost. Need to run os-prober again.
Is anyone else seeing this?

Have not updated grub2-branding on 12.3 yet.

Thanks to all that helped with this.
