If you format, fdisk, and partition the disks, you can use the slices for slogs. (You can also implement it in some other ways.) However, the point of the slog device is *performance* so you're defeating your purpose by doing this. People are always tempted to put more than one log onto a SSD because "Hey, the system could never use more than 8G, but I've got a 32G drive! What a waste of money!" Which has some truth in it. But the line of thought you should have is "Hey, the system will do its best to max out the 3Gbit/sec or 6Gbit/sec bus to the drive, so that disk is already fully utilized!" _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
