upgrade from latest 2.x to 3.0 fails?

[Netizen]

I am installing 2.3 and without doing anything else (apart from reboot) I am procceeding into upgrading it to 3.0

Running the upgrade script from 2.x to 3.0 does not seem to cause any issues however after the reboot the server (in a DC) is not booting anymore.
I have done this already twice and I'm not sure what causes it. Any ideas?

The second time, just before the reboot I did a grub-update:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.32-20-pve
Found initrd image: /boot/initrd.img-2.6.32-20-pve
Found linux image: /boot/vmlinuz-2.6.32-19-pve
Found initrd image: /boot/initrd.img-2.6.32-19-pve
Found memtest86+ image: /memtest86+.bin
Found memtest86+ multiboot image: /memtest86+_multiboot.bin
done


After the reboot the server is not accessible anymore.

This same thing happened to me, but after reboot server, grub waiting on start to select kernel, memtest .. etc. Timeout not working, working after adding hidden timeout to grub config and then update grub.

Why don't you install 3.0 directly then?

1) The DataCenter does not provide the image of 3.0. The image of 2.x works ok.
2) I want to do it on a few servers. If I ask the DC to put it manually it will be too expensive.

Can you provide a way to correct the Grub before the reboot? Not everybody is a linux guru...

We provide a correct grub config. Seems you run into a bug.

Same thing happened to me.
After many reboots and some changes on configuration, it works !
I looked into changes I made (for example in /etc/default/grub) but actually I didn't see anything relevant. It's a mistery ! May be there's a bug somewhere...

I'll have soon another server to install Proxmox from scratch, I'll try to reproduce the problem...
