    [PVE] High I/O delay when transferring data

    imo, ZFS for home lab is too costly if you need performance. keep ext4/Lvmthin over your hw raid, even better for iops switch to hw Raid10.

    My VM doesn't boot anymore. The VM disk is on a ZFS. SMART passed. Any ideas?

    can be a result of cache=writeback, crash at the wrong moment, then guest can lost important data. disable it.

    Change Pve Ip by web interface not change in welcome tty

    doesn't work because /etc/issue is generated each boot by PVE banner service. ip in /etc/hosts need updated too.

    Please explain LVM Thin making your existing Proxmox drive a mirror

    Why ?! ZFS for PVE OS only is perfect with spinners, there isn't slowdown. But ZFS on spinners for VM storage will be slow depending your guests and workload. For me, SSD are mandatory for Win10+ or Win Server 2016+

    Virtual Disk question

    truenas require its own dedicated disks, at least pass-through disks or better pass-through a hba. ZFS on ZFS is only ok to do some tests.

    Use raid hardware alongside zfs for Disks Setup

    integrated sata ports are provided by smart array b110i which is not a hw raid controller but a "software raid", better to switch the b110i to stock ahci controller then zfs will be ok. Remember ZFS isn't speedy.
