[auton-users] Request for Downtime

Hi.  I need to take Lofty(the fileserver) down for some disk upgrades 
and wanted to get an idea of when a day of downtime would be possible. 
Obviously, since this machine is rather integral to the lab network, 
this will have to occur on a weekend, preferably for an entire day, as I 
have a significant amount of data to transfer.  By no means does the 
downtime *need* to occur immediately, but I would like to accomplish the 
upgrade as soon as possible.

Long running jobs on the opterons which need access to BigPapa can be 
temporarily suspended for the duration, but would clearly face a higher 
risk of problems.  Jobs which do not need continual disk access, such as 
those reading/writing to /tmp could continue to run.  Desktop machines 
using BigPapa would be unusable for the duration of the downtime.

The Auton website and email will not be affected.

So, at the risk of giving too little notice, would this Saturday(10/9) 
through Sunday morning inconvenience anyone?  I know we had very low 
utilization last weekend.   If I hear of no objections, I will plan for 
this Saturday and send another email.  Please do speak up if there will 
be a better weekend for me to do this.

Thanks,
Jacob
