In case you read my last two posts and followed along, you now have an all flash ZFS on Linux based datastore. Only problem is, it’s not performing at all.
In the previous post I described how I mounted 4 NVMe flash drives in a single host in order to build an all-flash datastore. In this post, I’ll describe how to move from FreeNAS, TrueNAS (or any other ZFS host OS) to ZFS on Linux, and test if the performance is acceptable to continue with ZFS.
