OSCER users,


OSCER will hold a scheduled maintenance outage Wed Feb 28 8am-midnight.

Systems affected: supercomputer, OURdisk, OURcloud, OURRstore tape archive.

The OSCER team will perform the following maintenance items (time permitting),
in the following priority order:

(1) Shift to a new user database instance.

(2) Update Linux on OURdisk.

(3) Decommission our one older OURdisk monitor node (we have
5 newer monitor nodes, which are already in production alongside
the one older one, and the recommendation is to have either 3 or 5).

(4) Time permitting, upgrade one of the condominium compute nodes to
25GE (from its current 10GE).

(5) Time permitting, reconfigure the routing of the supercomputer's
Infiniband-to-Ethernet gateway appliances, and shift onto these
IB-to-Ethernet gateway appliances the network traffic of
(i) one compute node (for testing) and (ii) one of our scratch subsystems.

(6) Time permitting, shift all nodes to the IB-to-Eth gateway appliances.

We apologize for the inconvenience -- as always, our goal is to make
OSCER resources even better!
