Up to now all my OpenZFS installations were on Illumos/OmniOS due a superiour stability and the kernelbased SMB server. As Illumos lacks some newer but wanted OpenZFS features or newer network options like SMB over RDMA I am looking for alternatives that supports newest OpenZFS features like draid, raid-z expansion, direct io or fast dedup. Linux with SAMBA is an option but is a pain when it comes to ACL permissions compared to Illumos, Solaris or Windows. SMB direct/RDMA with an absolute superiour lan performance works currently best/only with a Windows Server as SMB server and Windows 11 clients with first tests on Linux + ksmbd. So no I am not on the way to leave Windows. I left Windows 15 years ago for ZFS.
I am on the way back to Windows due OpenZFS on Windows, SMB direct and the ACL permission and auditing features as the reasons. The current release candidate is quite usable and worth a look. Report back problems to get a stable release asap with snap versioning, encryption, hybrid pools and 1000x easier storage handling compared to Storage Spaces.
