UNPLANNED SERVICE OUTAGES


masters12 (grad net computer located in G61) is down due to a bad disk. Grad/Research Net users can use any of the other Grad/Research Net Linux systems until we've replaced the disk. No ETA on the disk replacement timeframe yet.


PLANNED SERVICE OUTAGES

Planned Service Outage #1

WHAT: Major CS Grad/Research Net services outage, as we upgrade its file server.

WHEN: Wednesday, July 6, from 12am to approx 9am.

DETAILS: One of our major CS Grad/Research Net servers will be shut down to be upgraded to new hardware and system configurations, early morning on Wednesday, July 6, from 12am until approx 9am.

That server, rtfm.cs.jhu.edu, is our CS Grad/Research Net home directory (/users) file server. It will provide us increased storage capacity, better performance, and improved redundancy.

As a result of this server upgrade process, several of our CS services will be unavailable during the shutdown/upgrade (described below). If there are any unexpected complications during the upgrade that will delay the restoration of services, we will update this Notices page.

Suspended (Unavailable) Grad/Research Net services while rtfm.cs.jhu.edu is down.

  • CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users (as this fileserver works in tandem with our mail server.) Incoming mail should be queued by the sender until our mail service is back up again. Outgoing mail will not be available.
  • IMAP, POP, and Webmail from our CS (Grad/Research Net) Mail server will be unavailable.
  • Some CS webpages, including user (and possibly lab and other CS pages), will be unavailable.
  • Grad/Research Net user accounts/home directories will be inaccessible during the downtime.
  • SMB File Shares (CS Office Staff uses these) will be unavailable.

  • ssh service to our CS Grad/Research Net Linux boxes (masters1 through masters16, gradx, and gradz) will be unavailable.
  • Console (desktop) access to masters1 through masters16 will be unavailable.
  • MySQL service via the mysql.cs.jhu.edu server will be unavailable.

Ugrad Net users: During the rtfm.cs shutdown/upgrade, email directed to your ugrad acct @cs.jhu.edu will not be immediately delivered. Other Ugrad Net services should remain available.

=UPDATE 7/6/16 7am

All is proceeding as schedule. We're still hoping for a 9am return to operations. Please check back here for updates.
