Guide to setting up XFS on top of ZFS on Linux Hardened Repository?


A little while ago we purchased an additional SAS storage enclosure for our existing Linux Hardened Repository server. Due to the number of disks, and also because we only have a Host Bus Adaptor rather than a hardware RAID card, we attempted to set this up as 5 md-raid6 arrays of 12 drives each, combined into a single volume using LVM.

While initially this seemed to be working, after a little bit we have been getting tons of I/O errors. We exhausted all possible troubleshooting steps in collaboration with Veeam support, but it just seems like this is a wrong setup for a Veeam repository.

I recently discovered the concept of “XFS on ZFS”, i.e. the idea of being able to set up a ZFS ZPOOL - which would replace the md-raid and LVM parts mentioned above - and then format this with the XFS filesystem. Apparently this is not a new idea either, as I found it was mentioned briefly in a Veeam webinar at https://www.veeam.com/resources/videos/build-secure-repositories-17144.html?rwty.

Does anyone know if there’s a detailed guide on how to set this up? As I could not find any instructions in the Veeam Knowledge Base or User Guide on how to do it?

Answering my own question, to my surprise the information given in the slides of the webinar turned out to be sufficient in order to set this up, it proved surprisingly simple.

I am not sure you will find anything on the Veeam site but maybe check the forums - https://forums.veeam.com

Other than that searching Linux forums and sites might be the only way to go.
