Well, poop! I just saw the ArsTechnica 2020 exposé about the WD Red SMR drives and realized that's the model of the six 4TB drives I got for this server...back in 2020! So, I guess I'll just move the ZVOLs off of this ZFS array, reformat it as an MDRAID instead, then move the virtual disks...

Thanks, @fiona . That explains it. That's highly unfortunate for everyone using ZVOLs for their virtual drives. Yes, discard was on, and fstrim did, in fact, reduce the size of the moved copy of the ZVOL back down to ~7.5G. However, I have a 300G virtual drive that has around 150G or so...

Thanks for your quick response, @Dunuin . I appreciate it. Yes, I just double checked. "Thin provisioning" is checked on both pools. Both pools are comprised of mirrored pairs, no raidz of any kind. The odd thing is that "zfs list" shows it as taking up all 32G, but the pool allocation...

I'm about to replace the HBA card used for my hdd_pool, so I want to temporarily move the ZVOL virtual drives of my VMs from the hdd_pool to the ssd_pool, just to be safe. I tested with one of the smaller virtual drives that's set to look like a 32G drive to the guest OS and has 7.52G actually...

Hi all. I have a new installation of 2.1 with a new KVM with Ubuntu 12 installed in it. The KVM's NIC is set to use NAT. Something assigned it an IP address of 10.0.2.15 and set its gateway to 10.0.2.2 and DNS server as 10.0.2.3. (1) Where did those IP addresses come from? I don't see DHCP...
