KSM error

[MikeAndreev]

Hi,
we have Proxmox cluster with 4 hosts

proxmox-ve: 6.4-1 (running kernel: 5.4.128-1-pve)
pve-manager: 6.4-13 (running version: 6.4-13/9f411e79)
pve-kernel-5.4: 6.4-5
pve-kernel-helper: 6.4-5
pve-kernel-5.4.128-1-pve: 5.4.128-1
........................................
ksm-control-daemon: 1.3-1

On one host I got next error (and stopped KSM daemon) in ~1 min after start KSM Tuning Daemon:

All parameters in /etc/ksmtuned.conf are commented (default settings) and the same on all hosts.
Any ideas?

the same error (on Proxmox 8)
did you solve the problem?

Hi,

the same error (on Proxmox 8)
did you solve the problem?

can you share the exact error message you get? The script /usr/sbin/ksmtuned comes from the Debian package ksmtuned, so you might want to report the bug there: https://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=ksmtuned

EDIT: I wasn't aware that Proxmox VE 8 does actually still provide a custom ksm-control-daemon package which can be used alternatively to the Debian one. A patch has been sent by @stfl that should address this issue: https://lists.proxmox.com/pipermail/pve-devel/2024-January/061460.html
