Yesterday I upgraded a Fedora server to 4.4.9-300.fc23.x86_64, after the reboot all my ZFS pools where gone. After some fiddling and testing I created these set of steps to solve the problem:
dnf remove zfs dnf install zfs modprobe zfs zpool import zpool import -D zpool import raid1 zfs mount -a
Can somebody acknowledge the same problem and is this to be more expected in the future?
ZFS version: zfs-0.6.5.7-1.fc23.x86_64
