Hi all,

I've downloaded new proxmox iso: Proxmox VE 8.4 ISO installer
Installing this on new hardware, so I can join my existing cluster, add ZFS pool and start migrating my VM's and demote the old nodes afterwards.

When I go to Node > ZFS I get this erorr.
Screenshot 2025-06-03 at 10.54.26.png

When I run modprobe zfs I get the following error:
modprobe: FATAL: Module zfs not found in directory /lib/modules/6.8.12-5-pve
What is the best way to install ZFS now?

Thanks in advance!

Hi!

Could you post the output of pveversion -v? Is this immediately after the installation or did you change anything regarding ZFS or run any upgrades?
 
meanwhile i did a full update and reinstalling

Hi! Thanks for replying!
This is immediately after installation.
Also added no-subscription repo, and ran upgrade, still same
i ran #apt install --reinstall zfs-dkms zfsutils-linux
rebooted
and still the same

its not able to load the module for some reason.

Code: 
# modprobe zfs
modprobe: FATAL: Module zfs not found in directory /lib/modules/6.8.12-5-pve

#pveversion -v

Installing zfs-dkms should not be necessary and it's a little weird that you're seemingly running on kernel 6.8.12-5-pve even after reboot when you've got 6.8.12-11-pve installed. Did you pin the kernel version?

Please try apt purge zfs-dkms and booting with the correct kernel version.
 
i have pinned 6.8.12-11
but still boots in -5

I pinned again, did refresh and did initramfs -u

still showing -5 after rebooting :(

Will try and install again from scratch again tomorrow morning with older iso i guess

I've reinstalled the server with Proxmox 7.4 ISO from the site.
After adding the repo, and upgrade & reboot I still have the same problem :(

The ZFS modules are not loaded.
Try running '/sbin/modprobe zfs' as root to load them.


root@snl-brd-pve01:~# /sbin/modprobe zfs
modprobe: FATAL: Module zfs not found in directory /lib/modules/6.8.12-5-pve

Within the syslog I do have a few "Function not implemented" messages, incl. zfs

Reinstalled again using a different ISO i still had on a DFS: 8.3
Still same problem ! :-0

root@snl-brd-pve01:~# ls /lib/modules
5.15.102-1-pve    5.15.158-2-pve

I don't even got the 6.8.12-5-pve folder
 
Issue is solved by reinstalling again ... with 8.4 ISO on a brand new USB stick.
Also after adding repo, and upgrading it works as expected
