For every system I have ever done zfs root on, it's always been a slice on a disk. As an example, we have an x4500 with 1TB disks. For that root config, we are planning on something like 150G on s0, and the rest on S3. s0 for the rpool, and s3 for the qpool. We didn't want to have to deal with issues around flashing a huge volume, as we found out with our other x4500 with 500GB disks. AFAIK, it's only non-rpool disks that use the "whole disk", and I doubt there's some sort of specific feature with an SSD, but I could be wrong. I like your idea of a reasonably sized root rpool and the rest used for the ZIL. But if you're going to do LU, you should probably take a good look at how much space you need for the clones and snapshots on the rpool Ben -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
