Thanks :) I was hoping (and I assume it’s the ultimate goal of the project) to be able to hot plug PCIe devices such as NVMe drives. On Solaris you can replace them provided you power them off previously (there’s a command for that, “hotplug”). On FreeBSD I’ve tried using devctl but powering off, disabling a device and enabling it again has led to a panic. Interestingly, I disabled nvme0 using devctl and "nvmecontrol devlist" didn’t find any nvme controllers despite having 10 controllers and 10 drives. However, the ZFS pool of 10 NVMe drives was working happily. Degraded of course, with one NVMe missing.
