Hi All, How would i obtain the current setting for the vdev_cache from a production system? We are looking at trying to tune ZFS for better performance with respect to oracle databases, however before we start changing settings via the /etc/system file we would like to confirm the setting from the running OS. Thanks Tony

By default, it''s set to 0xa00000 or 10MB. Regards, markm
