When running real data, as opposed to benchmarks, I notice that my l2arc stops filling, even though the majority of my reads are still going to primary storage. I''m using 5 SSDs for L2ARC, so I''d expect to get good throughput, even with sequential reads. I''d like to experiment with disabling the l2arc_noprefetch feature, to see how the performance compares by caching more data. How exactly do I do that? Right now, I added the following line to /etc/system, but it doesn''t seem to have made a difference. I''m still seeing most of my reads go to primary storage, even though my cache should be warm by now, and my SSDs are far from full. set zfs:l2arc_noprefetch = 0 Am I setting this wrong? Am misunderstanding this option? Thanks, Rob -- This message posted from opensolaris.org
