LVM it's probably fine with. Raid, MUCH less so. What you need to make sure does NOT happen is a lot of random writes. That might make deleting an lvm snapshot slightly painful ... But adding a SMR drive to an existing ZFS raid is a guarantee for pain. I don't know why, but "resilvering" causes a lot of random writes. I don't think md-raid behaves this way. But it's the very nature of raid that, as soon as something goes wrong and a drive needs replacing, everything is going to get hammered. And SMR drives don't take kindly to being hammered ... :-) Even in normal use, a SMR drive is going to cause grief if it's not handled carefully. Cheers, Wol
