We are currently converting our SSD-based Ganeti clusters from LVM on RAID to ZFS, to prepare for our NVMe future, without RAID cards (1). Was hoping to get the second box in our dev ganeti cluster reinstalled this morning to do further testing, but the first box has been working great!

1: LSI has a NVMe RAID controller for U.2 chassis, preparing for a non-RAID future, just in case.
