Zfs Problem

[gpetrom]

Hi
I am trying to install proxmox on hetner dedicated machine. After installing debian 11 base setup i am trying to install proxmox following the below guide.
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye
After it seems that installation is finished, zfs is not installed it. See the output from pveversion -v

As you can see zfsutils-linux is missing
I have tried to install zfs with the following commands
apt install pve-headers apt install zfsutils-linux zfs-dkms zfs-zed

and i am getting the following error

Setting up zfs-dkms (2.0.3-9) ... Loading new zfs-2.0.3 DKMS files... Building for 5.15.39-1-pve Building initial module for 5.15.39-1-pve configure: error: *** None of the expected "capability" interfaces were detected. *** This may be because your kernel version is newer than what is *** supported, or you are using a patched custom kernel with *** incompatible modifications. *** *** ZFS Version: zfs-2.0.3-9 *** Compatible Kernels: 3.10 - 5.10 Error!

I think that zfs in proxmox is installed it by default, am i wrong?
Any ideas what it is the problem?

Thanks in advanced

When installing the proxmox-ve package to a Debian it should automatically install a custom pve version of zfsutils-linux version 2.1.4. So ZFS should work out of the box. You can check whats installed with: apt list --installed | grep zfs
Should look like this:

libzfs4linux/stable,now 2.1.4-pve1 amd64 [installed,automatic]
zfs-zed/stable,now 2.1.4-pve1 amd64 [installed]
zfsutils-linux/stable,now 2.1.4-pve1 amd64 [installed,automatic]

But some packages are missing that would come with a installation from a PVE ISO. Like the "zfs-zed", "pve-headers" packages you already mentioned. And other stuff like "tsmtuned", "postfix" and so on.

Hi Dunuin

Thanks for the answer.
Yes zfs is not installed. The question is why ? and why it is not installing correctly when i am doing it manual.
Is there a way to fix this?

I don't got that "zfs-dkms" package and according to the error the PVE kernel and ZFS version is too high for that package to work.
