Proxmox gives me a blacksceen

Hello everyone,

I have a HP ProLiant ml150G6 server which I want to install Proxmox on.
Everything goes well and after the installation it reboots and gives me a black screen with a blinking dash. I have played with Debian, but I,m not an expert in it. :confused:

I tried to reinstall Proxmox which didn't work. I formatted the HDD's a couple of times in the hope that it only was a booting error from grub which eventually didn't help.

I'm clueless about this and I really want to try this out instead of using Vmware's ESXi.
It would be a shame to not use this software so that is why I'm here to ask anyone if they know how I can fix this. Didn't found much on the net or I didn't used the right words to search.

Hopefully someone can help me. :(
 
Hi,
this looks like, that you have two disks installed on your system and the disk-order is different between bios and system (so grub can't find /boot on the other disk).
Try to change the disk-order in the bios, or install with only one disk.

Hi Udo,

It is true that the same thing happens when u start an empty disk. At my bios I selected the disk where Proxmox is installed to boot first which didn't help. I'll try to get the other 5 HDD's out of the server in the hope that it will work.

Thanks Udo for the really fast reply!
 
Unfortunately it didn't work. Only one of the HDD's were still in the server and i reinstalled Proxmox on it, when it rebooted it gave me the same blackscreen with that blinking dash.

I also tried to install it on another HDD which was different from the first one, but even that didn't work.

Any suggestions? :confused:

Hi again,
so you don't see the grub-menu?! Your boot-order in the bios is right?!

Then you can only write the boot-loader again (live cd booting, like grml; mounting pve-root and /boot; grub-install). But this need a little bit experience.

But you can do the same what fnu has done http://forum.proxmox.com/threads/5991-proxmox-doesn-t-start-after-installation?p=34049#post34049 - put before the installation an usb-stick on the server. The installer use also them for the grub-installation.

I'm going to try this as soon as possible! Hopefully this will work. I saw this post but didn't thought it could help. :eek:

Thank you for the link.
 
I think I get it.

What I need to do is make a copy of ubuntu or anything with GRUB on it to my usb and boot that. When the GRUB screen comes I need to choose my harddisk with Proxmox and when I'm in Proxmox I can alter the GRUB that Proxmox use wherever that may be.

I'm going to do this after work.
 
Not sure what exactly you tried. I have seen at least one case where the ubuntu installer (i know you don't run ubuntu, but maybe this is more common) installed to wrong HD by default. ex: I have 5 600GB drives for raid pool, and 80GB drive for OS. That one is /dev/sdf and I told installer to format and install there and it did. It also (and I am lucky I saw this) installed grub on /dev/sda, which was not in boot order in bios. What was suggested was physically unplug all drives but OS drive, do the proxmox install, then power off and plug all drives back in (and make sure you go to bios to have those drives not in boot sequence.)
 
That is very strange that Proxmox will try to install grub on another HDD. I'm going to try this out in the hope that I can play with Proxmox!

Fingers crossed :D
 
Yes it works! I'll reboot and use Ubuntu's live cd to format the other drives and hopefully it will boot the Proxmox again! Thanks for all the help.
 
Oh hindsight, cruel hindsight...
I had three raid partitions on a server: data-1, os, data-2
I installed Proxmox 1.8 to the OS partition and everything seemed alright. The computer in question is a test server and its insides get rearranged from time to time. I was having trouble setting up DRBD, the "previous experiments" were being detected. My efforts to delete the leftover DRBD / LVM data must have taken GRUB as well. It doesn't help that I was playing around with the boot order in BIOS at the same time.

Moral of my story: plan your partitions and disk layout before you install, verify your theories and avoid "flexibility" when it won't be helpful.
