  |details=JHU Networking will be swapping out all of the Hopkins-managed Malone Hall ''wifi'' access points in the building. They plan to start work around 11am that Friday, and they expect it could take 4 hours, more or less, to replace them all.  During that time, wifi access might disappear and reappear.  Additionally, when your wireless device tries to reconnect to the newly-replaced access point, you ''might'' be prompted to accept a certificate, and we were informed that you should do so.<br/>

::JHU Networking has indicated they are testing power transfer equipment in Mason Hall that will affect several buildings, including Malone and Hackerman.  They will be cycling power to the buildings, perhaps several times.  They expect their outages to be < 10 seconds each.
  
::'''WHEN:''' Saturday, June 26, starting at 8pm
+
::Our CS IT servers that provide you most of our IT services should remain up and running, since our servers have backup battery power.  Unfortunately, the JHU network in the building does not.  So, you will probably experience brief network interruptions when the power is cycled by Facilities.  And each time the power is out, CS services that you interact with (email, web, home directories, etc.) will be inaccessible due to the building's network being unavailable during the outage times.
  
::'''DETAILS:'''
+
::Faculty who run their own servers in the CS Server Room (MH G-29), please note that if you do not have UPS units in your racks (and most of you do not), you can expect your systems will power cycle each time Facilities cycles power in Malone Hall.  Please be aware.  PhD students who maintain those systems (and perhaps other systems in the building), please keep that in mind as well.
  
 +
::The CS computing labs' systems (currently, for the summer, all located in G-61), those computers are not on UPS systems, so those computers will power cycle and should boot back up on their own.  But, if you're planning to use our lab systems, because they might go up and down several times during the electrical work time period, you might not want to do your school work on those systems during that time.

::JHU Facilities is preparing for BGE to test electrical equipment that affects several Homewood buildings.  They will be performing this test on Saturday evening, June 26 at 8pm.  If you recall, back on May 6, there was a very short power outage that affected our building and others.  The testing BGE will be doing is part of their troubleshooting what happened in May.

::'''WHAT:'''
 
  
::'''WHEN:'''  
+
:JHU is experiencing email issues with it's @jhu.edu mail services due to a global outage at Cisco.  This affects both incoming and outgoing email messages to external recipients.  It also impacts systems that send email through JHU's email gateways.  Expect major mail delays until this is fixed.  (We suspect that those with @jhu.edu addresses can still send and receive to others with @jhu.edu addresses.)

====Major Malone Power Outage Planned (Affecting CS IT Services) - Saturday, March 30 from 6am to 2:30pm (CS IT Services Outage before and after Power Outage as well)====
  
'''WHAT:''' Major CS Grad/Research Net IT services outage, as we update our file server system.  
+
:'''WHAT:''' There will be '''''no''''' CS IT computing services available during an upcoming all-day major power outage for ALL of Malone Hall.
  
'''WHEN:'''  ''Tuesday morning, Oct 13, 5am to approx. 6am.''
+
:'''WHEN:'''  Power Outage - Saturday, March 30, 2024, starting at '''6am''' and running until '''2:30pm''' (so, roughly, 8.5 hours.)
  
'''DETAILS:'''
+
:: Loss of CS IT services - Saturday, March 30, 2024, starting at '''5am''' (one hour before the power outage) and lasting until '''4:30pm''' (two hours after the power outage is completed.)
:Our CS Grad/Research Net home directory file server, ''rtfm.cs.jhu.edu'', will be rebooted so that a time-sensitive, required update can be applied.    We will apply the required update this coming Tuesday morning, Oct 13, starting at 5am.  We expect the reboot and configuration to take no more than an hour if all goes well.
 
  
: During the process of applying the update, several of our CS services will be unavailable.  A list is below.
+
:'''DESCRIPTION:'''  JHU is planning an a all-day power outage for Malone Hall, and all of our computing services will be unavailable during that time.
  
: If there are any unexpected complications during the update process that will delay the restoration of services, we will update this CS IT Support Wiki's Notices page.
+
:The actual power outage is planned to start at 6am, Saturday morning, March 30,, and will continue  for approximately an 8.5 hours.  '''''However,''''' we need to safely bring down our computer servers and clients ''earlier'' than that (before the power goes out.)  We plan to bring our systems down that morning around '''5am'''.  And although the power to the building should restored around 2:30pm that same day, we will not have all our systems back up and running until approx. 4:30pm, so plan on about 2 hours after the power outage is deemed over until our servers and services are available again.

+
:<span style="color:#ff0000">Please read all of the notes below regarding Malone Hall Residents, CS Server Room users, and a list of the CS IT services that will be unavailable during the outage. </span>
 
 
* CS Mail service, both incoming and outgoing, will be suspended for CS Grad/Research Net users.  Incoming mail should be queued by the sender until our mail service is back up again.
 
 
 
* IMAP, POP, and Webmail from our CS (Grad/Research Net) Mail server will be unavailable.
 
CS IT Support Wiki
 
* 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 and some CS faculty and grad students use these) will be unavailable.
 
 
 
* SSH service to our C.S Grad/Research Net Linux boxes (masters1 through masters16, gradx, and gradz) will be unavailable.
 
 
 
* Console (desktop) access to masters1 through masters16 will be unavailable.  However, since users are not currently allowed in the CS labs, this should not be an issue.
 
  
* MySQL service via the mysql.cs.jhu.edu server will be unavailable.

::<span style="color:#ff0000">'''NOTES TO MALONE HALL RESIDENTS:'''</span>  During the time of the outage, we're assuming most building lights will be out and the J-Card system might be out too.  That might make it more difficult to get into the building during the outage.  But with the power out, we're not sure how much need there will be for anyone to be in the building during that time anyway.  If you have an office refrigerator, expect that to be out too.  If you are counting on your UPS (battery-backup) systems to continue powering your office equipment, keep in mind the expected length of the outage (8 hours) and plan for a longer period of time, just to be safe.  And keep in mind that your office phones may be inoperable during the outage.  So please plan in advance for this outage.

:'''WHAT:''' Linux kernel bug causing some of our Fedora 31 lab systems to hang.
+
'''CS IT Services That Will Not Be Available During The System Maintenance:'''<br/>
 
 
:'''WHEN:''' First identified in CS, last week of January, 2020.    '''''UPDATES below the DETAILS section...'''''
 
 
 
:'''DETAILS:'''
 
 
 
::As you know, recently, we upgraded our lab Linux clients to Fedora 31.  Over the past several days, we've discovered some odd behavior from some of the lab systems.  Upon further investigation, we have learned that there is a kernel bug that is causing some systems to hang (requiring a reboot) when certain NFS operations are performed.  (NFS is the system that allows our Linux clients to access the home directories, certain apps, other shared file systems.)
 
 
 
::We're seeing that the bug is documented and that it affects not only Fedora 31, but some prior versions as well.  It just happens to be that we are seeing its effects now.
 
 
 
::This is a Linux kernel issue and there are Linux folk working on trying to get this bug patcMarch 22hed, but we do not know how long it will take.
 
 
 
::In the meantime, CS IT is looking into work-arounds to bypass this bug as much as possible.
 
 
 
::There is no way to predict if or when this bug will cause a system to hang.  Some of our systems may never notice it.  We think it might happen to some systems that are heavily utilizing NFS operations, but again, we're not sure.
 
 
 
::Our recommendation is that when you're editing files, etc. save your work on a regular basis, just in caseThis is a good practice to follow anyway.
 
 
 
::'''''IMPORTANT:'''''  If you experience a system that hangs (and doesn't recover after several minutes), please email  {{mailto|support}} to let us know the name of the system that experienced the hang, the time of the hang, and what activity you were doing on the system at that time (which will help us troubleshoot the problem further.)
 
   
 
::We will update here with our progress on circumventing this bug.
 
 
 
::'''UPDATE:  1/29/20'''  We are applying alternative pre-bug kernels to those  Linux clients that are available to be rebooted (to activate these kernels.)  As more become available, we'll reboot them as well.  We're hoping these alternative kernels will prevent the hangups until officially patched kernels become available.
 
 
 
::'''UPDATE: 2/7/20''' We have applied updates to most of our systems in order to activate the alternative pre-bug kernels, which we hope will prevent hangups.  There are still some systems which have not yet had the alternative kernels applied, and that will happen as the systems become available for us to reboot.

:'''WHAT:''' Malone Hall MH 122 '''and''' Malone Hall G61, both the Masters and Ugrad sides of the lab, '''and ''all'' the lab Linux computers, will be closed to CS students due to an ACM Programming Contest.
<!--:'''WHAT:''' Emergency reboot of ''blaze'', the dept's main Grad/Research net mail server.
 
  
:'''WHEN:''' ''(TODAY!)'' Tuesday, Dec. 12 @ noon and lasting approx 1/2 hour if all goes well.
+
:'''WHEN:'''  Starting Friday evening, Feb 23, 5pm '''through''' Saturday, February 24, 9pm.
  
:'''DETAILS:'''
+
:'''DETAILS:'''  
  
::We have discovered an issue with our mail spool disk on ''blaze'' our Grad/Research net mail server which must be corrected right away.  As such, we expect that a configuration change and reboot should fix the problem.
+
: Both the MH 122 '''and''' G61 Masters and Ugrad Labs will be used for an ACM Programming Contest and will therefore be '''''closed''''' to those not participating in the contest.
  
::We plan to do this shortly, at ''noon today (lunchtime.)''  The reboot should take approx. 1/2 hour if all goes well. If there are issues, it might take some additional time to complete the repair. 
+
: Additionally, all of the labs' Linux computers (grad1 through grad16 and ugrad1 through ugrad24) will be unavailable during the time period referenced above.
 
 
::During the reboot time, there will be ''no CS email service in or out of the CS Grad/Research network.'' You will not be able to send or receive mail (IMAP/POP/etc.) through blaze (smtp.cs.jhu.edu/pop.cs.jhu.edu) or via webmail during that time. Also, DNS might be slow or non-existent, depending upon your client's own configuration.
 
  
::You also might experience slow connection times to www.cs.jhu.edu.
+
* During the lab closure times, compute servers, gradx.cs.jhu.edu, gradz.cs.jhu.edu, ugradx.cs.jhu.ed, and ugradz.cs.jhu.edu '''''will continue to be available remotely''''', via SSH.
  
::Grad Net Lab Linux systems (masters1 through masters16, gradx, and gradz) may experience a short delay as their NIS service connects to a different server.  
+
* We have to take down the lab systems late that Friday afternoon.  At the end of the ACM contest that Saturday night, the coordinators of that contest will be turning our lab computer systems back on.  Most should boot normally.  But, if some do not, just trying using an alternate one in the lab.  We'll be back in the Monday afterwards and can check on any systems that didn't boot normally.  (And don't forget, as mentioned above our compute servers -- gradx, gradz, ugradx, ugradz -- will continue to be remotely available, even if the lab systems are not.)
  
::Any updates and notice of completion will be presented through this NOTICES page today.
+
* The printers in MH 122 and MH G61 will remain online, but, please pick up your printouts outside of the contest hours.

:During the network outage, CS systems might not be seen by each other, and network traffic between CS and outside-of-CS may be halted.  Many CS services will be unavailable when the network is unavailable.  Again, JHU Networking expects this to be a brief network outage, so you might only experience a short system hang.
 
 
 
We will update this Notices page in case there are delays with restoring any of our services.

:'''WHEN:''' Wednesday, January 18, from ''8am to approx 11am''.

<!--  **VM Server Shutdown TEMPLATE **
 
 
'''WHAT:'''  The dept's Virtual Machine will be shutdown.
 
 
'''WHEN:''' Wednesday, January 11 from 6am to 3pm (or earlier)
 
 
We need to do some work on the VM server and will be taking it down during the above date and time.
 
 
As part of the shutdown process, we will suspend most or all of the VMs; some
 
VMs might have to be shutdown all the way instead.  And when the VM server is back up and running again, we will restart or unsuspend all VMs.  In all cases, VM owner intervention should not be needed; we can handle this remotely.
 
 
After the VM server is up and running again, VM owners will receive an announcement (and updates will be posted here), and, we do ask that VM owners check to make sure their VMs are running as expected.  Please email [mailto:support@cs.jhu.edu support@cs.jhu.edu] if there are issues.

'''WHAT:''' ugradz.cs.jhu.edu (one of our CS Dept Linux Ugrad Net compute servers) will go down for a memory upgrade.
 
 
'''WHEN:''' Thursday, April 6, from 9am to 11am.
 
 
'''DETAILS:''' ugradz will be taken offline so that its memory can be upgraded.  While ugradz is down for its memory upgrade, you can still access our other Ugrad Net Fedora 25
 
systems (ugrad1 through ugrad24 and ugradx.)  Info about our Fedora systems can be found at:  https://support.cs.jhu.edu/wiki/Category:Linux_Clients
 
 
Please make sure you are logged off of ugradz before the upgrade time.
 
 
Any updates will be posted here.
