[linux-lvm] Unable to boot system

[linux-lvm] Unable to boot system

[Pratik Solanki]

Hello,

I am a newbie to LVM and recently installed Fedora Core 2 with LVM. I
have 2 hard disks, only one of them is used in a volume group. I have
4 logical volumes in the group, /, /usr, /home and swap. Everything
was wonrkinbg fine until I decided to upgrade my system through yum. I
used the development releases since I wanted gnome 2.8. I did not
update everything; instead I just updated selective gnome packages.
After rebooting my system refuses to come up. It says something like

Uncompressing Linux ....
...
Reading all physical volumes. This can take a while ...
Found Volume Group "Vol0". metadata lvm2
4 logical Volumes in volume group "Vol0" now active
Restarting System

I can use the fedora rescue disk and mount all the volumes without any
problem. I did notice that when I was restarting, my systems showed
errors when disabling swap (swapoff), but it went by too fast for me
to write down the exact error. Something about /dev/mapper/LV03 not
found.

Any ideas on what is causing this and how I can fix it.

Thanks,
Pratik.

Hi Pratik,

I'm afraid I'm not far past LVM newbie myself.

One problem I had was the startup scripts for Mandrake 10.0
'intelligently' determined whether I was running LVM1 or LVM2 by the
presence of configuration files.  (The configuration methods differ
between the LVM1 and 2).  As I had been messing around with both LVM1
and LVM2 I had a mixture, and this destroyed the logic of the startup
script.

It might be worth having a little look through the startup script to
figure out where it's going wrong, and maybe that'll point you at the
answer.  I believe Mandrake is similar to RedHat, so chances are that
your startup script is also /etc/rc.sysinit.

It's worth noting that the script expects errors in some situations and
retries some operations again later.  So seeing errors during boot isn't
necessarily a problem...

Of course, it might be failing before you get to the startup script, but
that would suggest something modified your initrd image during the
upgrade, if the upgrade is the cause and not a red herring.

Cheers,

Frank
