zfs_arc_max only working on 1 of 4 servers

Dec 26, 2018

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

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

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

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

Proxmox 1, 2 and 3 is running boot disk in zfs "raid1"
Promox9 is just running a single boot disk
Yes. All of them, one by one.
