Hi All,
I have three ESXi Hosts in a cluster running the latest version vCenter 6. Each host has 120 Gig of SSD used for Virtual Flash Resource Management. I have 10 VMs assigned 5 gig of virtual flash. By my math accounts, that would be 50 gig usage out of 120 gig. However, often times, when putting the ESXi hosts in MM for patching, I get an error saying the VM cannot be migrated do to a lack of vFlash resources on the other hosts.
I can overcome this obstacle by removing the 5 gig vFlash assigned to the VM. However, I don't understand how/why/what consumes the SSD for vFlash. I doubt this is a bug, since I have had this issue since a fresh install of ESXi 6 when it first was released last year. Could anyone give me some insight on why this is not working as I would expect?
Thanks!
