OSCER users,


Resending this scheduled maintenance outage alert.

Although our records show that we sent this email
this past Thursday (Aug 29) at 5:48pm Central Time,
we've had reports that some of y'all didn't receive it.

Our apologies for that -- it's not clear what went wrong
with this listserv.

Henry

OSCER users,

Supercomputer/OURdisk scheduled maintenance outage
Wed Sep 4, 8am-midnight Central Time

OSCER will hold a scheduled maintenance outage
for the supercomputer and OURdisk, specifically:

* Update the operating system to Enterprise Linux (EL)
version 9.4 on one of our /home diskfull servers.

* Replace OSCER's old internal database with a
new, better database.

* Reboot OURdisk's metadata server (MDS), to
establish a new set of connections to the compute nodes
and other clients, and to verify MDS backup failover.

* Upgrade the 4PP data center's power infrastructure to
accommodate more GPU nodes and compute nodes.

* Upgrade network connectivity on one of our storage nodes.

As always, we apologize for the inconvenience --
our goal is to make OSCER capabilities even better!

The OSCER Team ([log in to unmask])
