ESXi 5 shows a datastore with no free space but it's empty

Hi all,

We have a HP P2000 FC storage and I did set up a new 2.4 Tb LUN and presented it to the ESXi cluster.

All the hosts can see it fine ( Capacity 2.18 Tb and Free Space 2.18 Tb ). See highlighted AS1DR_FR5_L13

The issue occurs when I add a new 2 TB virtual disk to one of the guests....

Then after creating the disk, the datastore is showing with 184.29 Gb free only but there is nothing in there.

I did delete the Volume and vDisk on the HP P2000 storage, created it again with different sizes but I'm having the same results.

Do you guys have any idea on what is going on ?

Cheers

Fabio
