That's exactly how I interpreted it.Please quote where i said zvols don't fragment?
Is that how you interpreted this: "the 'fragmentation' issue wouldn't be a problem."
It's not harder to replace drives.. you replace a drive in the WebGUI just like the manual says to. You don't have to do any more or less clicks of the mouse if it were fill disk.
You know how many people have had to go with a smaller swapsize so they could resilver disks? *Many* people have had to replace a disk with a refurbished disk(or another spare) and found that the spare is 100kb too small. So what do you do? You set the WebGUI swap size to 1.5GB and you do the resilver.
There are TONS of reasons why the swap space is useless but extremely, extremely useful. Don't knock it. I find it interesting that you're going to argue over what is literally going to be a rounding error for disk sizes these days.
If you understood all of the aspects of how FreeBSD works you'd realize partitions are the way to go. I'm sorry but I'm not going to explain it any more than I already have. Plenty of topics on this already if you want to read them.
Take care.
