February 12, 20251 yr I have 64Gb od memory and my server is no where close to utilizing half of it, so I'd like to allocate more of the ram to the ZFS Cache. I can't seem to get the cache limits to stick (or at least show up utilized on the dash). In Tools->System Drivers i set the ZFS cache with the following script (I commented the original values in the event I need to go back to default): # LimeTech - Default ARC size is MemTotal/8 (in bytes) # default 8395400192 # using 12GB ZFS Cache min and 32GB max below in bytes options zfs zfs_arc_min=12884901888 options zfs zfs_arc_max=34359738368 Dash shows the following: I tried without setting the min value and the results were the same. Any ideas?
February 12, 20251 yr Community Expert Solution the dashboard shows you what is actually IN the cache. Of course it may be less than the min value because if there is no data to store, how shall he fill the memory? I dont see any sense in setting the min value (did not even know that it existed before your posting 🙂 ) Copy some files to the zfs disk(s) then you will see the dash value raise.

Thanks, I was just coming back to say exactly that. After running some transfers it loaded up the RAM. You're avatar is perfect for my misundertanding!
