How can I tell if a disk is SMR?
My setup consists (relevantly) of one pool with two two-disk mirror vdevs, each made up of 10TB disks. I'd like to increase my storage capacity by adding one disk and converting everything to a RAIDZ2 group (yes, I know I have to completely restore the data from backup, not change the topology on the fly). I have a spare 12TB WD Elements drive that I'd like to shuck and use for this purpose, but how do I tell what's inside it?
The List of known SMR drives thread only says, for Elements disks, "Precise models vary and are not guaranteed; assume SMR in capacities below 8TB". Neither hdparm nor lshw tells me anything that makes sense to me.
Is it safe to use this disk for this purpose?
