[linux-lvm] Unable to boot system

[Frank Dean]

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
