[Planetlab-users] yum fail on some planetlab nodes

[Justin Cappos]

I've seen rebuilding the database even after wiping these files not
work before.   It may be easiest to destroy that sliver and start
fresh.   You can do this through the PLCAPI API or use the webpage to
remove the node, wait for it to disappear, and the readd it.

Thanks,
Justin
