zfs 2.1 roadmap
- Thread starter alexskysilk
- Start date
Are you sure that pve-kernel 5.11 test ships with ZFS 2.0.6?
On my test node I see:
Yes, pretty sure, I did the build
https://git.proxmox.com/?p=pve-kernel.git;a=shortlog;h=refs/heads/pve-kernel-5.11
The thing is that we do not divide user-space tools per major version in separate packages as they're backward compatible anyway. So, if you just update but do not install the
pve-kernel-5.13 package you'll get 2.1.1 user-space but 2.0.6 kernel module.You can check both, user and kernel version with
zfs -V, for example:
Bash:
zfs -V
zfs-2.1.1-pve1
zfs-kmod-2.0.6-pve1
uname -a
Linux prod2 5.11.22-5-pve #1 SMP PVE 5.11.22-10 (Tue, 28 Sep 2021 08:15:41 +0200) x86_64 GNU/LinuxAnd for 5.13 based kernel it looks like:
Bash:
zfs -V
zfs-2.1.1-pve1
zfs-kmod-2.1.1-pve1
uname -a
Linux prod1 5.13.14-1-pve #1 SMP PVE 5.13.14-1 (Tue, 28 Sep 2021 06:16:44 +0200) x86_64 GNU/LinuxYes, pretty sure, I did the build

Thomas, thanks for clarification.
Are they (user-space 2.1.1 and kernel 2.0.6 100% compatible?
Thanks for the @mention, but it wouldnt do me any good now since I cant reform a pool retroactively...
In the future I will no longer use zfs anyway so its not really an issue. (and if you're asking, cephfs)
Backward compatible, sure. You naturally cannot use newer features the user-space tools would know already about (e.g., draid).
*sad ZFS noises*
If you have the infrastructure to run Ceph in a serious manner thats a great alternative tho!
@t.lamprecht
Just booted into 5.13 on my workstation, running PVE & PBS together.
So far, nothing explodes.
ZFS also allows me to upgrade my pools to use the new 2.1 dRAID:

Proxmox VE 6.4 is in bug & security fix only mode since the release of Proxmox VE 7.0, so we won't take in new feature releases of upstream project, iow. PVE 6.4 will stay on ZFS 2.0.x.
As mentioned, it's only on the
pvetest repository at time of writing, it will move to no-subscription in a bit and only later to the enterprise repository, at least if no issue pops up.Do you plan to update 5.11 kernel in pve 6.xx version to latest ZFS (2.0.7)? User-space tools was updated to 2.0.7 recently.
No, 5.11 won't get any update anymore, you can update to 7.x if you require a newer kernel:
https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0
The 5.13 kernel is the current default there, and the 5.15 is also available as opt-in.
Those can manager the slightly older 5.11 kernel module just fine though.
