<p>I did not receive any feedback on the date for bringing on the
new Lustre system. A date has been chosen: Thursday, August 8th
(later than the original July 24th target). I am assuming that
this is not a problem for us.</p>

<p>Folks,</p>
<p>There will be a need for an interruption of our cache disk use
to bring on new Lustre disk space (about a petabyte for all of
Physics) and to upgrade Lustre software on the old system. All
of the files already backed up to tape will disappear from
cache; to access them they will have to be re-fetched from the
tape library. Also new farm jobs will not start if they will run
over the transition.</p>
<p>The proposed date is Wednesday, July 24th. The computer center
has asked for feedback on the schedule. Let me know if you know
of reasons why this is <b>not</b> a good time for the outage. </p>
