Client: Help, emergency. I have 24 hours to move my workload to another server. What do we do?
Me, five minutes later: "Done. Your workload is now running on the new server."
Client: "How did you move over 200GB with just a minute of downtime, from one provider to another and in a different country?"
Me: "Thanks to FreeBSD, ZFS, and a little bit of proactive planning."

I have a task that replicates all the VMs from one server to another every 15 minutes using zfs-send/zfs-receive. This VM connects to a VPN with two reverse proxies.
Meaning, when I move this VM, we don’t need to change any IPs since it’s not directly exposed.
I powered it off, cloned the differences in seconds, and restarted it.

Client in disbelief.
Me, relaxed and happy.

Thank you, FreeBSD, thank you, ZFS!

Has anyone ever had this issue with NVMe SSDs?

"A device which does not exist was specified."

Is this a hardware defect? The drive (PNY CS3140 1TB) is only about 5 weeks old. It seems to fix itself after a couple of reboots, but it's very annoying. Linux doesn't seem to have any issues with it yet.
