Comment 5 for bug 620027

Other than the earlier suggestions (merge in the error checking branch)...

What perplexes me is that it looks like pvcreate is succeeding in both cases, because a PV appears to be created.

If it's not dependent on the order in which you run the commands, then perhaps it's a permissions problem? (I wonder if the sudo is causing trouble). Who are you running this as? Can you try running as root (e.g. sudo bash beforehand).

Also, I noticed you seem to have uid and gid flags... do you by any chance have ~soren/nova/derootification merged in? Are you running off a clean trunk?
