We have a production server which does nothing but nfs from zfs. This particular machine has plenty of free memory. Blogs and Documentation state that zfs will use as much memory as is "necessary" but how is "necessary" calculated? If the memory is free and unused would it not be beneficial to increase the relative "necessary" size calculation of the arc even if the extra cache isn't likely to get hit often? When an L2ARC is attached does it get used if there is no memory pressure?
Thanks, Chris
