<p>Hello everyone,</p>
<p>as already announced on Slack, we'll be performing maintenance on
the Hall A counting house computers (servers and desktops) in
first half of September. Expect occasional reboots and temporary
outages. Some reboots have already happened, so if you find a
session gone, that's why.</p>
<p>In particular, we will</p>
<p>- Upgrade all Alma 9 systems to Alma 9.6<br>
- Upgrade the remaining CentOS 7 systems to Alma 9.6 (except adaq3
for the time being)<br>
- Upgrade the hardware of adaqsc and adaqfs<br>
- Deploy a new machine, avideo1, for serving live and timelapse
video of the hall cameras<br>
- Decommission the unused ancient workstation avideo2<br>
</p>
<p>Also, the counting house disks will be cleaned up after November
1. Legacy ROOT files, log files, etc. (SBS and otherwise) will be
removed. If you care about any of these (mostly online replay
results), please copy them to long-term storage (e.g. MSS).</p>
<p>Additional computing upgrades (new machines) for MOLLER will
happen later this year or early next year. There will be a
separate announcement for that.</p>
<p>Please contact me with any questions and concerns.</p>
<p>Ole</p>
<p><br>
