zfs_nocacheflush
I have a Sunserver M5000 running Solaris 10 8/07 with one zpool .The zpool is on a EMC san . We have a poor performance on our progress databases and I will like to try to disable cache flushing . (from zfs Evil Tuning Guide) My question is : can I turn off chache flushing online : echo zfs_nocacheflush/W0t1 |mdb -kw
