VCL AVD profile storage reset
View Details
Task Number: CHG0036293

NOTICE: On 12/19/2024 9:15am, VCL AVD profiles will reset for the next semester. The VCL AVD profile storage is intended for semester use of the resources required to access course instruction and classwork. All AVD users have a profile that is used when logging in to various AVD servers. The profile contains each user's data and settings such as Documents, Downloads, Desktop, and Application.

At the scheduled time, staff will archive the Fall 2024 profile storage, update related GPO's to utilize the new spring 2025 profile storage

on-prem VCL reservations failing
View Details

Final Update (2:46pm): The remaining affected reservations have been fixed. If you are still experiencing issues, please contact vcl_help@ncsu.edu for support.

Update (1:45pm): The core problem causing this issue has been identified and resolved. Most things are back to normal. There are still a few reservations staff are manually fixing.

Update (10:13am): Now that reservations are getting IP addresses, we're seeing lots of sluggishness with connections to them.  Staff are still investigating.

Update (9:42am): The issue with getting IP addresses is resolved.  New reservations should deploy correctly now.  Staff are currently working on finding and correcting any reservations missing IP addresses.

After a network change late on 10/31, on-prem VCL computers are no longer getting IP addresses. This is causing most new reservations to fail, and some existing reservations to lose their network connection. Staff are working on fixing the issue.

Task Number: CHG0032029

Sunday May 8th 11pm through Monday 5pm VCL resources will be degraded for network maintenance.  Staff will be migrating physical network connections that will disrupt a sub-set of VCL resources. The impacted users have been notified separately. No impact is expected for additional VCL resources in Azure or another DataCenter location.

WVD services through VCL are degraded
View Details

Update 4/9 8:33am - A little after midnight, Azure notified us that they had sufficiently mitigated the problem to allow things to function normally. They are still in the process of fully resolving the issue. Access to WVD resources should be working normally now.

----------------------------

Update 4:19pm - Azure is having a problem with management of resources in the datacenter our resources are in. We're still waiting on them to resolve the issue.

---------------------------

Microsoft Azure services used to manage WVD resources are currently not working well. It seems that running systems are still working okay. However, we can't scale WVD resources up as more people use them. If too many people try to use the existing resources, they will get overwhelmed. Staff are looking in to the problem.

Problems using VCL WVD systems
View Details

Update - 1:18pm 8/24
The quota limit has been increased. Users should be able to log in to WVD normally now.

Original message - 11:55am 8/24
Users started experiencing problems when logging in to VCL WVD systems around 7pm on Monday (8/23) afternoon. Problems include only seeing a few icons on the desktop and not seeing applications in the Start menu. The cause of the problem has been identified as a quota limit on the storage where all user profiles for WVD are stored. Staff are working on getting the quota increased. User profiles include places like Documents, Downloads, Desktop, Start menu related items, and application configurations.

User profile space is not intended for long term storage of files. The NCSU Drive (B:) and Google Drive File Stream need to be used for long term storage of files used in WVD.

VCL service degraded due to network port
View Details

Around 5pm on Friday 8/6 a network port failed on some VCL hardware. This affected about 30 existing reservations and prevented new reservations in the same datacenter from being created. Reservations in the affected datacenter have IP addresses starting with 152.7.98 or 152.7.99. Service was restored around 10pm.

3/15 10:03pm update - Access to resources in the Azure Portal is working correctly again.

3/15 7:53pm update - Microsoft has implemented a fix that is apparently slowly taking effect. Logging in to WVD resources appears to be working at this point. Access to resources in the Azure Portal does not appear to be working correctly yet.

Microsoft is having an authentication issue that is affecting WVD resources that are available through the VCL site. Currently connected users can remain connected, but new logins are failing or showing users have no access to any resources.

Azure NCSU resources
View Details

Resolved: Created new session hosts with new naming scheme as a work around. MS support case remains open to determine root cause.   

 

An issue with the Azure WVD NCSU host pool was discovered last Friday which prevents managing underlying virtual machines for the general NCSU resources. This issue does not allow the power on virtual machines as new users connect to dynamically grow compute capacity. All related VCL application entries have been redirected to a higher end set of resources. As a temporary fix students will need to choose NCSU-HeavyApps.
