Well, the maintenance was going fine up until the point the system got
pulled forward by accident and the power cable pulled out the back.  So
so much for uptime :)

On the plus side, the drive replacement is finished successfully and the
main array is just finishing up with reconstruction.  There is now some
additional space available -- I will figure out what to do with it soon
and make it available to users.

An extra thanks to Derek for heading into Boston to do this.

Thanks for your patience,
Dan
