Ubuntu 16.04 LTS - Server: What are the differences in performance between a ZFS (no RAIDZ) and a LVM - Of course by using the same HDDs. I used LVM for a long time until a fatal day I got a HDD failure (without the possibility of have a good backup for my 20TB). I need to take a decision (please: beside trying a good backup) between use LVM again or create a RAIDZ0 ZPOOL. What is the best option and why?. Thanks for your help.
First I have no info about RAIDZ0, but if follow RAID numbers this is stripping. In such case it does not matter if you use LVM with striped volumes of ZFS. Will be better to reconsider your "RAID" strategy to use something like RAID5 or 6.
In sense of management LVM need more handwork, ZFS do automatically many things w/o need of operator intervention. But ZFS is "imported" from Solaris and IMHO its far far away from current ZFS because meanwhile Oracle develop a lot of good things in Solaris.
So my recommendation is to use LVM with proper RAID level
