Heads up for a data corruption bug in ZFS, few versions affected, might have started at 2.1.x, but many reports on 2.2.x
That did not work for me on ubuntu, but did on my debian/proxmox distribution
proxmox:
zfs-0.8.3-pve1
zfs-kmod-0.8.3-pve1
ubuntu:
version: 0.6.5.6-0ubuntu26
srcversion: 0968F94158D646E259D86B5
vermagic: 4.4.0-142-generic SMP mod_unload modversions retpoline
looks like im using an ancient version and am ok?
