Adding ram to a cluster

[Pablonhd]

Hello, I have a two node cluster (2003 /w PAE enabled) I wish to add ram too. The existing nodes both have 4 gigs of ram and I will be adding 4gigs to each.

I was under the impression I could move resources around and take each node down one at a time to add the ram. This would reduce downtime. To date I have not been able to do this.

Bring down the first node, adding the ram, and bringing it back up seems fine. The problem is I cannot move resources back to that node. The resources get stuck at "pending online". Eventually the whole cluster will fail. Shutting the node down with the extra ram causes the cluster to comeback online.

Anybody have any thoughts?

Do you have any /3GB or /USERVA switches set in the boot.ini file?

What resource fails when moving to the node that you took down? Has the cluster service started correctly? What is in the application and system logs?

As it turns out removing /3GB fixed everything.

This is contrary to ms's own documentation.
