Which variable?

 

[tac12345]

vfs.zfs.l2arc_write_max 200MB True
vfs.zfs.l2arc_headroom 4 True
vfs.zfs.l2arc_noprefetch 0 True
vfs.zfs.l2arc_write_boost 380MB True

Sysctls use MIB values (dotted format), so that is your case here. Tunables tend to be driver names followed by a _load.

thanks ! but in both case, setting will be applied before the pool is imported?
