ZFS tune (zfs_arc_min, zfs_arc_max) ?

[user623]

Migrate from CORE to SCALE.

Previous (CORE) i can control ZFS over sysctl (use tunables). How i can control zfs_arc_min, zfs_arc_max on SCALE on boot ?

I try use script/command as:
modprobe zfs zfs_arc_min=53687091, zfs_arc_max=1073741824

and

modprobe zfs c_min=53687091,c_max=1073741824

but no have effect:

These can be changed with the commands:
echo SIZE_IN_BYTES >> /sys/module/zfs/parameters/zfs_arc_min
echo SIZE_IN_BYTES >> /sys/module/zfs/parameters/zfs_arc_max

You will need to add it as a preinit command under the "Init/Shutdown Scripts" selection for the change to persistence across reboots.

Tnx.

Hmmm...very strange. I try it before, and not have result. But after few reboots (2..3) now all looks fine. ))
