Cloning fails

larstr — Thu, 10 Feb 2011 07:59:30 GMT

CMU 4.2.1

I've installed a master node with RHEL5.5 and the backup works fine. However, when I'm trying to clone the image it fails:

If I boot the RHEL55 CD in rescue mode and mount the partitions I'm fully able to chroot into the install. Why CMU is unable to do so is a big question....

Whoa.. yer building an HPC Cluster?

Hopefully some HPC afficionado is lurking here. Else, suggest you hit http://hp.com/go/cmu and check if there is anything out of of spec to what you are trying to do and if RHEL 5.5 is even supported.

This too:

You using Myrinet? or HP's brand of Innfiniband?

Looks like the nodes undergoing cloning are not able to access the commands in the "/"
partition of the backup image.

Have you specified the correct device name for the root partition during backup/cloning?

This forum is for generic cmu questions/discussions
only. These sort of issues must
be escalated through standard HP support
channels.

We figured this out. We were trying to clone using the default logical group. The solution was to use a different logical group.

..and yes, we're building a HPC cluster. Hope to see increased activity in this forum. :)

Chris Holmes (CMU) — Thu, 26 May 2011 14:15:42 GMT

This is fixed now. CMU v5.1 will now error if you attempt to clone with the 'default' logical group.

Hope you got your HPC cluster up and running!
