Bill, In the future, you can try: # lockstat -s 10 -I sleep 10 which aggregates on the full stack trace, not just the caller, during profiling interrupts. (-s 10 sets the stack depth; tweak up or down to taste). nice. Perhaps lockstat(1M) should be updated to include something like

First, ZFS allows one to take advantage of large, inexpensive Serial ATA disk drives. Paraphrased: ZFS loves large, cheap SATA disk drives. So the first part of the solution looks (to me) as simple as adding some cheap SATA disk drives. I hope not. We have quotas available for a reason.
