May 27, 20251 yr Hello,I'm trying to create snapshots of a windows VM that's hosted on a ZFS drive. I have 744 GB free. The VM itself is several TB, though most of that is in a secondary drive (it's a gaming VM, all the games are on the second drive).My understanding is that a snapshot is only a diff anyway, so it doesn't need to clone the entire disk. I would think that the 744 GB would be sufficient space for that, especially considering not much changes on it now other than updates, but when I try to create a snapshot I get an error for insufficient storage.I need more information on what the hangup is-do I need room for a full clone? Can I only snapshot the (relatively small) system drive? Any advice is appreciated, thank you.
May 27, 20251 yr Author Some more information:I was able to snapshot a Linux guest VM with no issues. I also got more options to use the ZFS native snapshot, which I don't get when trying to do the Windows VM. I do see the Linux VM has qcow images for hard drive, while the Windows VM has .img files. Not sure if that matters?
