Anyway, why did you deploy a VCSA with 500 GB?
I've choosen "Small" in the deployement size when I upgraded, it should be 340GB total (According to this HowTo : )https://www.virtualizationhowto.com/2018/04/upgrading-to-vmware-vcenter-server-vcsa-6-7/ )
I'm close to 100 VMs.
I added the attachments to this post.
Thanks for the help!
Nobody has an idea on how to proceed ?
I missed the previous update.
Seems that you will have to live with it.
Here is another thread where it was discussed: Reduce VCSA disk size
At least, if you have thin disks you won't waste all that space.
Hope this helps.
There are ways to shrink the size (converter or attaching vmdk from a new vcsa) of /storage/seat.
I was able to help one of my customer to reduce /storage/seat from 1.4TB to 100GB.
