Cortex XDR 8.9 Non-Persistent Citrix Servers and Cache Write Issue

[M.Rivera653095]

Hello everyone,

We have encountered and issue where the target servers do not get content updates.  The citrix Windows servers reboot nightly with the golden image configurations but do not receive the latest content updates.  At the same time, around noon we have to reboot the target servers due to write cache filling up to 100%.  Have you encountered similar issues and what did you do to remediate?  Thank you!

Do you use brokers?
Are you able to run cytool connectivity_test?

Hi Tiago,

We do not use brokers.

Thanks,

When you create the Golden image you did this steps:

• Ensure the agent was installed with the VDI flag: msiexec /i cortexxdr.msi VDI_ENABLED=1.

• Force a content update: Run cytool content update (or check-in via the console).

• Crucial: Run the "Image Prep" scan. This pre-verifies files so the targets don't have to do it live:

  cytool imageprep scan timeout 4 upload 95 path C:\temp\

• Wait for it to finish, then shut down and promote the image.

on agent VDI profile check this:
