Hello,
I am too just setting a new system up. I have 24GB of memory in the box and would like to use that as a cache. From research, the method to do that is to create a zfs volume and use a file extent under the iSCSI menu (correct if wrong please). Similar to the post below, I am having issues determining the space to use.

This has generated two questions:
Question 1: If my installation is on a separate 8GB USB drive, do I still need to worry about the upgrade space referenced above?
Question 2: I have tested that I can over allocate the available space. Does data corrupt or will the system simply halt if that occurs? Is there a reason this is possible?
While the two volumes are 8x2TB and 8x500GB each configured in a hardware RAID5, I still want to be as efficient as possible with the resources while keep performance ideal.
Thanks!
