I typically use ZFS on Solaris or FreeBSD but would recommend using a different zpool for swap if you can so you can have a different vdev layout more suited to that load (ie, RAID1 rather than RAID5) and/or to tweak other settings as desired independently of your data zpools
Either way, definitely provision your swap zvols as thick volumes so that you have all the space you might need pre-allocated and you won't force the system to hunt for more at the point where it is already under load. Regards, Malcolm -- Malcolm Herbert m...@mjch.net
