We have 2 LUN that have been presented to an ESX 3.5 server. Both LUNS were formated as VMFS with the default 1MB blocksize for a VMFS filesystem.
We have now to place a big VMDK file in one of the Datastore (blank with no information named DS1) that goes beyond what the 1MB blocksize limit can handle.
Could someone walk us through the steps we have to follow in order to change the blocksize for this datastore? The Datastore does not contain any data and is a LUN that it has been carved on the SAN.
