Oops – wiped out the production server

I have the privilege (ha!) or managing our infrastructure for our development team.  This includes our source code server, our CI server, jira, wiki etc.

I decided for convenience these should all be virtual machines, running on one of the servers we rent from the very reasonable (and pretty helpful too!) http//ovh.co.uk.  I use the excellent proxmox GUI from http://proxmox.com to manage them all.

Anyway, we need another server as we are outgrowing our existing one (or will do soon), so I rented another one and have been in the process of experimenting –> re-installing –> experimenting cycle that a new box always encourages.

For convenience, I number the physical machines host, host1, host2 etc.  The new machine is called host, the existing production machine is host1.

OVH provide an excellent manager which remotely lets you re-install a (fairly large) number of preconfigured operating systems – one of which is proxmox, so for the fifteenth time I started the re-installation.  And then yes, you can see where this is going, yep – I had selected host1 instead of host thus wiping out all 12 of our development machines in one foul swoop.

GULP!

And no, there is no way to cancel the installation….
