Bug#616689: Root-on-LVM setup fails often due to timing issues
I too have issues with this problem.
For all of our Dell PowerEdge servers I've needed to use the rootdelay parameter.
Ages ago I used to have it set to rootdelay=10
Then a number of months ago after some upgrades the failure was happening again.
I had to bump it up to rootdelay=20
Today I upgraded a virtual machine running on VMware VSphere from kernel 2.6.32 to 3.0.0.
It is also exhibiting the boot problem of not finding the volume group fro the root mount point.
Adding rootdelay to it fixed it.
The rootdelay parameter seems to be a moving target, and increasing it too much adds an unnecessary delay to boots.
I was finally going to report this when I came across this bug report.
I'll try the scsi_mod.scan=sync option as maybe this won't cause unnecessary delays?
But it would be good to have this fixed as standard.
Francesc, maybe try 'dpkg-reconfigure grub-pc' and specify the parameters that way?
You might have more luck with that...
