Unable to import ISO (zfs, zvol issue)

OK thanks for trying it. I don’t really know what else to try. I can work around the problem (and I don’t really need to import ISOs - there are other ways for the odd occasion I might want one).

incus config device add myvm archiso disk source=/path/to/my.iso boot.priority=2

Is it worth adding an issue about this on GitHub, do you think?
