I am using a boot lun size of 5GB. but vmware said I need a 5.2 gb for scratch?
I was still able to create a 4.1 gb vmfs volume from the 5gb boot lun after esxi install.
any idea?
In this case not all partitions were created on the 5GB LUN, and you may need to create a persistent scratch location manually.
