Since yesterday several of our customer's monitoring alerted us, that Fileserver drives, which host FSLogix VHDX files, see significant usage growth. We had to emergency expand several drives today and yesterday, to stop a potential Citrix outage. Anybody else seeing significant VHDX growth in the last few days?

I heard nothing currently... This was a thing in the past: Google Chrome's silent 4GB AI download problem [updated] | Malwarebytes

Can you compare the contents within a few profiles between Monday and Tuesday? Any common apps/software between your customers that downloaded updates within their appdata?

funny enough - i had the same thing happen yesterday but we use CPC not FSL.

@Andy Stadtlander yes I could. Just need time to do so ^^

mount the largest containers give it a drive letter and run a windirstat usage report on it. I have recently had issues with containers growing large and it was the M365 apps autorecovered data consuming GB's within the profile container C:\users\appdata\local\Microsoft\excel. Had to run a container cleanup script to mount and remove all the autorecovered docs and then a compaction script to free up the white space after deletion
