File Server Slowness

by

Access to EECS home directories on home.eecs was particularly slow for a while this morning. For users with mail or browser profiles in their home directories, this may have prevented their mail client or browser programs from functioning normally.

Access to project.eecs does not appear to have been affected.

Staff are investigating the cause. The likely culprit are slowdowns from a new backup combined with replication.

The symptoms disappeared at 9:30am on Tuesday, Sep 09. More should be known about the root cause by 9am Wednesday.

Cory Transformer Upgrade

by

Physical Plant will be shutting off all the power to Cory Hall to switch
transformers on Wednesday night, June 4th from 7pm to 9pm. This will
allow upgrade of our back up transformer located in the basement. The
building will be closed from 6pm until 9pm for this event. Please ensure
your lab equipment and computers are prepared for this event.

Please contact Scott McNally for questions or Mark Davis (642-1468) in
room 253, Cory Hall.

Note that CUSG will be on-site during this time, and will coordinate the shutdown of CUSG-supported servers in Cory Hall, and later will get them back online when the power is restored.

CUSG will attempt to power-off all CUSG-supported Cory Hall workstations (Windows PCs and Linux workstations) starting at 5:30pm. CUSG will power-off all CUSG-supported Cory Hall servers beginning at 5:45pm. Some may be online as late as 6:30pm, as we continue shut-downs remotely. Servers will be brought back online as soon as power is restored.

Soda Hall computer services should continue normally.

Bounced email to help@eecs

by

A configuration problem caused all email to help@eecs to bounce this morning, citing “User unknown”.

This was related to work on migrating some back-end CUSG services to a new server.

We apologize for any inconvenience this may have caused.

Network Disruption

by

From about the time of the routing changes this morning in Soda, some systems have had trouble with NFS mounting of partitions from coeus and project. The problem appears to be isolated to specific systems. The problem does not affect all systems moved to a new router this morning. The problem does not appear to be reproducible on all systems on any specific network.

At least one affected client machine seems to be fixed after a reboot.

Staff are continuing to investigate this issue.
