ZFS

Is there any plan to expand XOSTOR with ZFS ontop of the LINSTOR/DRBD layer?
Here is a example of a HA setup with DRBD and ZFS:

Hi,
We do not use DRBD directly but LINSTOR. LINSTOR on top of ZFS might work, but it's far from being a priority now.

Understandable, I forgot that this is built ontop of LINTSTOR and not on DRBD directly.
I belive then this post by LINBIT is more appropiate.This stack which is outlined seems interesting as it means we could for exampel use ZFS as volume manager and create a mirror-1 zpool for fast access, and raid-z2 or zfs draid for the slow access. Utilizing LINSTOR and DRBD for distributing this across the cluster. And utilizing bcache to unify these two zpools for using the fast/slow tier.
I understand that right now the storage controller api of xcp-ng and xo is not setup to utilize such a setup. but could I potentially setup a ext4 or zfs filesystem ontop of this stack and use the already existing storage controller infrastructure, or would I be losing out on either performance and/or features by doing so.
