June 13 2019: Slowness on /z/Proj spaces

We recently added new drives to expand the space on /z/Comp, but the server hardware really does not like some of these new drives. Because of how the system works, it is taking us a while to replace those drives. It'll probably take until well into the weekend to get the drives swapped out for ones it prefers, and there will unfortunately be intermittent access issues until that task is complete.

We will update this note when we have all the new drives swapped in.

Dec 13 2018: New Bitcoin Scam Seen on Campus

(From the Office of Cybersecurity)

Colleagues,

Please be aware that the Office of Cybersecurity and the UW Police Department have received reports of a new Bitcoin (cryptocurrency) email scam. The message claims that a bomb has been placed in the building that the recipient is in and demands a large Bitcoin payment. This scam has also been seen nationwide at businesses and other educational institutions, including the University of Washington at Seattle and Penn State.

Aug 20, 2018: Email delivery problems

Late last week the BCG made some changes to our name server configuration at the request of DoIT (Outlook integration). Unfortunately, in making those changes we introduced a bug into how email addresses are resolved. This error caused email from outside the UW Outlook system, to @biostat.wisc.edu addresses, to fail to deliver. Email sent to your @wisc.edu address, or sent entirely from within UW's Outlook, would still be delivered as normal.

July 31 2018: R 3.5.1 ready

The newest version of R, 3.5.1, is ready and usable with the path /s/pkg/linux64/R/3.5.1/bin/R. After some testing, we will make this the new default, in a few weeks.

Some packages have dropped maintenance since the last update:

  • deal - very old
  • msgl
  • ncdf - replaced with ncdf4 package, which is now installed
  • ReporteRs
  • epicalc

If you need a particular replacement package for one of these, please let us know.

July 18 2018: Directory Difficulties

Today one of our file servers had a drive fail. The normal failover process worked, but unfortunately took long enough to confuse a bunch of machines.

The usual symptom is that directories (home directories, project directories) will not attach. Often your login session will just hang.

Unfortunately, this takes a hard reboot to fix reliably. We are checking a bunch of the open login and compute servers (Wednesday afternoon), and rebooting as we can.
