I don't want to take my array, containers, and VMs down to change a single setting (in this case, enabling SMB Multi-channel), but by the time I need to take the whole thing down for whatever reason, I will absolutely forget to set it before restarting the array and the cycle continues.

Plenty of other settings fall into this cycle too though. When I was first setting up it took me 4 different times before I finally remembered to set my array's new name before starting it.

A good suggestion, but I personally don't understand why people are so afraid of rebooting or even restarting the array. I mean, set your vm's to hibernate and you're back to the way everything was in like 10 seconds after restarting the array. But I support your suggestion 🙂
