zfs_arc_max only working on 1 of 4 servers

[potetpro]

Hi.

my /etc/modprobe.d/zfs.conf on all servers look like:
options zfs zfs_arc_max=573741824

I have tried running:
update-initramfs -u

on all servers.

and the result currently is:

root@proxmox1:~# cat /proc/spl/kstat/zfs/arcstats | grep c_max
c_max 4 67530100736
root@proxmox1:~# cat /sys/module/zfs/parameters/zfs_arc_max
573741824

root@proxmox2:~# cat /proc/spl/kstat/zfs/arcstats | grep c_max
c_max 4 67574499328
root@proxmox2:~# cat /sys/module/zfs/parameters/zfs_arc_max
573741824

root@proxmox3:~# cat /proc/spl/kstat/zfs/arcstats | grep c_max
c_max 4 42207549440
root@proxmox3:~# cat /sys/module/zfs/parameters/zfs_arc_max
573741824

root@proxmox9:~# cat /proc/spl/kstat/zfs/arcstats | grep c_max
c_max 4 573741824
root@proxmox9:~# cat /sys/module/zfs/parameters/zfs_arc_max
573741824


Proxmox 1, 2 and 3 is running boot disk in zfs "raid1"
Promox9 is just running a single boot disk

on all servers.

Only to be clear because you did not write it explicitly: You rebooted your machines after the changes, right?

Yes. All of them, one by one.


update-initramfs: Generating /boot/initrd.img-5.0.21-1-pve
Running hook script 'zz-pve-efiboot'..
Re-executing '/etc/kernel/postinst.d/zz-pve-efiboot' in new private mount namespace..
No /etc/kernel/pve-efiboot-uuids found, skipping ESP sync.

Found this post:

Saying he got it working using: pve-efiboot-tool init /dev/device
I am running zfs raid1 on my boot volume, do i run the command against both disks?
