OpenZFS on Windows rc9 is out
The recent problem with several zfs snaps is fixed, had no problems with update and a snap mount.

Jorgen Lundman
"Bring in the verdict on rc9, let me know what things are still broken. You don't want me with nothing to do for long. I as curious about the long filename patch, but if I sync up, we will be 3.0rc from now, and the feedback was to hold back on too-new features."

Not anyone with a single problem with this OpenZFS 2.2.6 release on Windows?
The items on my trouble list are solved. Is this the "still beta but usable one"

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.

Whether with or without ZFS, there seems to be no way around using Windows Server as a NAS if you want a really fast SMB server with RDMA (e.g. with 25G nics and 3GB/s over LAN with low latency and CPU load).

A current Windows Server is available as Datacenter and Standard with an unspeakably complex and expensive licensing model for servers, CPU and core numbers, each with a minimum and Client Cals and RDP Cals.

Fortunately, there is Server 2022 Essentials, ideal for a Windows NAS.
Hardly more expensive than a better Windows 11 license and very simple in terms of licensing.

See the Windows Server pricing and licensing overview .

Windows Server Essentials 2022 is a restricted Windows Server license for small businesses, limited to one server with one CPU and a maximum of 10 cores and one VM. Otherwise, the Essentials Edition has the same features as Windows Server 2022 Standard. A maximum of 25 users or 50 devices can be managed. Access (CALs) does not have to be licensed here. Use as a terminal server, with associated RDS CALs, is also possible with the new version. Windows Server 2022 Essentials is available as a very cost-effective OEM license with or without hardware.

btw
OpenZFS on Windows seems to be very fast now, quite as fast as ntfs (beside 4k)

OpenZFS on Windows crashes with local CDM benchmarks
On some cases there are import problems of pools

Windows 2022 Essentials with SMB direct/ RDMA + a future ZFS is slowly becoming my first choice for a high performance NAS.

Updated OpenZFS for Windows rc10 with a fix for a Crystal Diskmark and mount problem
Releases · openzfsonwindows/openzfs
  • Fix UserBuffer usage with sync-read/write (CrystalDisk)
  • Handle mountpoint differ to dataset name.
From week to week less, minor or very special problems thanks to intensive user testings and the hard work of Jorgen Lundman .
Try it and do not forget to report remaining problems to go from a usable to a stable state.

Windows + ZFS + local sync of important data to a ntfs disk seems already a very good option for a ZFS NAS or Storageserver. If you need superiour performance, combine with Server 2022 Essentials for SMB Direct/RDMA

** OpenZFSOnWindows-debug-.99-3126-g97bdecb6f.exe

Testing install of zed

Zed is a ZFS fault management service to monitor and log ZFS.
It also automounts last imported pools on bootup.

OpenZFS on Windows 2.2.6 rc 11 is out

rc11:
  • 32bit tunables was using 64bit and unsettable.
  • zfs mount would userland assert
  • GCM nested cpu calls
  • tunables would not survive reboots
Important is the fix on a mount problem and with encryption using gcm. Tuning via registry should work better.
Additionally zed (ZFS error daemon) is included to log events and to automount last used pools.

Please update, install for testings and report back problems.
ZFS on Windows especially paired with Server 2025 (Essentials) will give a storage server with a unique feature set.
My napp-it cs web-gui already supports the new features Raid-Z expansion and fast dedup for evaluations beside Storage Spaces settings.

Let us hope for many testers
This is declared as a release edition, not release candidate.

Beside superiour ACL management, SMB Direct with nics 25-100G is the killerfeature for a fileserver based on Windows Server. OpenZFS on Windows is now 2.3 with direct io to disable the time and resource intensive Arc caching on fast NVMe pools what can improve pool performance.
