Unable to install OpenNode 6.0b1, switching to CentOS method

(1/1)

Zucan:
I am trying to install OpenNode 6.0beta1 on an Dell Optiplex 790. 

The first problem i run into is that it fails to acquire a DHCP address properly.  It is trying to configure the network on eth0.  I find it interesting that CentOS6 detects the interface as em0 and not eth0.  I wonder if OpenNode is confused about the interface somehow and forces it to eth0 anyways.  In any case, if I configure the interface manually within the installer, the network comes up just fine and the install process moves forward.

The next problem occurs after I answer the question about whether or not I do automatic partitioning or manual partitioning.  I chose automatic.  After that, it appears that the installer changes the video mode on the graphics card and it soon locks up.  The keyboard doesn't do anything and the cdrom stops spinning.  I restarted the installer using the "basic video" option and I get the same exact result.  Any ideas on how to get past that?  My gut tells me that it is likely video related, but without anything on the screen, I can't see what errors are being generated.

So, ultimately, I am left with the "convert CentOS6 to OpenNode" option.  I have read the forums and notes on the site.  It doesn't look difficult.  But some questions come to mind... Obviously, when doing a native OpenNode install, it partitions the disk according to its desires.  Since I have the option of controlling partitioning during the CentOS6 install, is there a recommended setup that I should use when doing the CentOS install?  The last install I did shoved all the remaining free space into /home, which I imagine is not ideal for OpenNode.  Are there any other recommended settings that should be chosen for the CentOS install?

I will wait for a response before proceeding on the CentOS conversion.

1) When multiple network interfaces exists on the machine OpenNode installer should present them all and let you to choose which one to configure. Installation wont proceed without right interface having link status - eg cable in place. Strange interface names can happen - or out of order interface detection - but I imagine pure CentOS installer detects these the same way.

2) We have seen this GUI (X) mode installer stalling problem - but not yet fully understand the problem behind it. Could you try to push CTRL+C on the keyboard - to see if installer falls back to text console mode and goes forward?

3) You can partition your host any way you want - OpenNode itself automatically tries to make 3 separate partitions:

a) root - not more than 10G needed - min 5G
b) /storage - for KVM disk images and templates
c) /vz - for OpenVZ VM-s

Swap should be 2xRAM - but no more than 8G needed.

But you can actually very well live with single root partition - /vz and /storage folders will be created automatically and you could migrate these later to another block devices if needed.

I forgot to come back with a response on #2 below, which is the issue with the display seemingly locking up during the install.  I tried various things, such as changing resolutions are part of grub, text mode, etc.  None of that worked.  The one method that DID work, however, was a reverse VNC back to my desktop that gave me a graphical window where I can do the install.  I saw my VNC client on my desktop up to allow other clients connect to it and then pointed the OpenNode install to connect to my desktop via VNC and it just worked...  Maybe that trick can help others that run into the same problem.

It sounds like video driver issues in kernel - could you please run official centos installer and see if problem still exists?

Zucan:
The CentOS installer runs fine... In, fact, I had already installed CentOS before I decided to try OpenNode.  However, that being said, when I did do the OpenNode installer, it was off the 6.0 beta release, not the current 6.0rc1 release.  I have no idea if it was fixed between those releases.

FYI, I am not going to reinstall my system at this point... CentOS or OpenNode.  I have a good working OpenNode setup now and I'm not touching it :)

I installed OpenNode 6.0rc1 at home and didn't have any display issues... But it is a completely different hardware set, so I am not surprised.
