It was a recent Proxmox version (newest ~6 weeks ago). It's possible that I used some experimental new kernel version and haven't tried on completely basic/default setup. The disks were Samsung's MZVL21T0HCLR-00B00. The pair with ext4 sw raid booted all VMs (Linux, FreeBSD) with no issues but second pair with ZFS pool wouldn't. It may have been due to the newer kernel version but I asked myself a few questions about what's missing in FreeBSD's bhyve regarding my needs and took this route instead of trying default kernel. # zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT VMs 952G 828G 124G - - 36% 87% 1.00x ONLINE - zroot 944G 1.21G 943G - - 0% 0% 1.00x ONLINE -
