arc_summary Error in proxmox

[awptechnologies]

i have replaced my boot drive by using sgdisk to configure the partitions to match old drive. create zfs snapshot. I then did a send and receive to new pool removed old disk and everything seemed perfect. It booted fine all my vms are there and working. My issue is with arc_summary i get this error: ZFS Subsystem Report Fri Nov 03 13:39:39 2023 Linux 6.2.16-19-pve 2.1.13-pve1 Machine: Earth (x86_64) 2.1.13-pve1

KeyError: 'meta'

Original exception was:

If i run arc_summary -r it prints everything with no problem. Is this something that will be fixed with update or is there something i can do about this issue?

It looks like you are trying to run arc_summary from OpenZFS 2.2 on 2.1.13.

how do i fix good sir when i do zfs --version i see zfs-2.2.0-pve1 zfs-kmod-2.1.13-pve1

[amotin]

Install user-space and kernel module from the same version.

[awptechnologies]

can you help me out with that i ran apt-get install zfs-dkms and did modprobe zfs but its still the same

[awptechnologies]

sorry never had to go this in depth with zfs

[awptechnologies]

@amotin is this correct

[awptechnologies]

Fixed it. I upgraded to 6.5 kernel and it's fixed. Seems like proxmox pushed update for user space before the actually kernel. When I manually installed kernel it worked instantly. Also I removed zfs-dkms. It didn't seem to need it

How to install: Ensure that either the pve repository is set up correctly. You can do so via CLI text-editor or using the web UI under Node -> Repositories

• apt update
• apt full-upgrade # to get ZFS 2.2 user space packages
• apt install pve-kernel-6.5
• reboot
