You don't need any usb stick and Windows. On hp website there are available rpm packages for Red Hat with online flash utils included. I used them from Proxmox on DL380 G6 and G7.

zfs destroy zpool/vm-101-disk-1 If You have zvol snapshots then: zfs destroy -r zpool/vm-101-disk-1 to destroy all.

You can use 4k volblocksize, but zfs will write 4x4k for every 4k from zvol. Zvol with 4k block will use 4GB on zpool for every 1GB size. Thread creator have zvol with default 8k block and his zvol use 2GB for every 1GB size.

ls -l /dev/disk/by-id

Your problem is volblocksize. Because You use RAIDZ2 with 6 disks and ashift=12 (4k block) your minimal volblocksize is 4x4k (4 stripes + 2 parity).

How do You try to mount, because for me it's working this same with any logical block size used. Try to do: fdisk -l /dev/your-pool/your-path/to-zvoland then trymount -o loop,offset=512×first-part-sector /dev/your-pool/your-path/to-zvol /your/mountpoint

Yes. It is possible. Read about STP: https://excitingip.com/1688/understanding-spanning-tree-protocols-stp-rstp-mstp/

Did You try options-> hotplug?

In hardware You can change bios to OVMF (UEFI). Try, disk is UEFI already but You need proper bios.

I would recommend create vm with settings from virtualbox and convert vmdk to raw image: qemu-img convert -f vmdk -O raw GSM-TRIAL-21.04.4-VirtualBox-disk001.vmdk /dev/path/to/vm-disk-nnn

4k random reads will be faster with 8k volblocksize because zfs reads only 12k from disks. With 16k volblocksize it must read 24k from disks. But this is when compression is off. You could try use 12k volblocksize with lz4 compression and format ext4 in guest with stripe-width=4 then test. If...

volblocksize = ashift * number of stripes not mirrors. For ashift = 12 You have 4k block on disk: 2 disk mirror ZFS writes 2 * 4k block with same content 2 disk stripe ZFS writes 2 * 4k block with different contents (8k) 6 disk stripped mirror (3 stripes * 2 mirrors) ZFS writes 3 stripes * (2...

You can use simpler hookscript: #!/bin/bash function launch() { nohup /usr/lib/kvm/virtiofsd -f --socket-path=/var/run/shared-fs.sock -o source=/zp0/ct0/subvol-103-disk-1 --cache=always --syslog --daemonize &> /dev/null & return 0 } if [ $2 = "pre-start" ]; then...

Do not use stride parameter when formatting ext4 in guest. This is not real array from quest view. Use for 32k: mkfs.ext4 -b 4k -E stripe-width=8
