I’m setting up a new iSCSI LUN / volume and am wondering what the
recommended sector size is.



The setup wizard recommends 8KB for vmware.



I’ve read that QCOW2 uses 64KB blocks? Does this mean I use 64KB on the
iscsi LUN? Sorry if this is a stupid question.


Yes, qcow2 uses 64K, but I'm unsure if that's optimal in any way to the
underlying disks.
I doubt it makes a noticeable difference.
