I think I've figured it out. It may be completely wrong, but the way I was causing the PXE boot was to zero the boot sector of the node before the reboot. I increased that to 10Mb to make sure the partition table was zeroed as well, and now the process seems to work. I'm still interested if anyone else has encountered something like this and what a better solution might be.
Thanks!

I've dug through logs, read source, googled and binged and can't seem to find an answer that moves me forward. If you can help, I'd greatly appreciate it. I have a pool of VM's running in a VMWare vSphere cluster. Crowbar is running fine and PXE booted these nodes and was able to allocate them. Note that the "bios" and "raid" are both set to "not set" on all of these nodes. I then applied some barclamps and that worked fine as well. I want to return some of these nodes to an unallocated state (with all of the "junk" that the barclamps put down removed), so I issued the command: crowbar_machines reinstall <node_id> And then forced the node to PXE-boot. We're not using BMC, so I had to force the node to PXE-boot, but I presume that's ok? It PXE-boots fine and then enters the loop waiting to be allocated. When I later allocate the node, it fails booting Ubuntu with the message: Partition disks - Volume group name already in use. I've tried "reset", "reinstall", and "delete" and none of them give me the behavior I want, which is just to "give me a fresh new system." So my questions are: 1) Do I have the process correct for "returning a node to an unallocated state"? 2) Why would the volume group still be set after a PXE boot? 3) What else can I do to track this down? 4) What additional information can I provide to help?
