Can rebooting both nodes of a Microsoft Windows 2003 Cluster blow away the cluster?

I have rarely done this, but I deployed packages that automatically rebooted two cluster nodes (physical servers). Now I see "NTLDR is missing" on both nodes. Did I blow away the cluster? Ideas?

The identity of the active cluster is maintained by the quorum drive. As long as the quorum drive is accessible and ANY ONE of the nodes can still boot you will have an active cluster (with just that one node as a member). Rebooting them at the same time will not harm the quorum drive or the ability of the cluster to attach to the drive and determine its place in the world.

Now whatever you did to wipe out the NTLDR is going to hose your cluster nodes, because NTLDR is part of the boot loader and no operating system will load without it. That is your real problem. But you can replace the bootloader once you boot the node with a bootable image on a CD. Make a bootable CD and then replace the missing boot loader components.

If you want to know how to make a bootable CD it will cost you more than 25 cents. : )

Asker's Rating:

• Thanks. It is strange that this info is noticeably lacking on the internet. I just wanted to know if rebooting them at once would mess anything up. I've always wondered, "If two nodes failing at the same time destroys the cluster, no rational enterprise would be using the technology!"
