ZFS supports swap to /dev/vzol, however, I do not have data related to performance. Also note that ZFS does not support dump yet, see RFE 5008936. I am getting ready to install a new server from scratch. While I had been hoping to do a full-radiz2 system, from what I am understanding here,

I am getting ready to install a new server from scratch. While I had been hoping to do a full-radiz2 system, from what I am understanding here, my best bet is to still do a UFS drive for the root/boot partition, since ZFS does not support dump. Is this correct? There is no official support

I took a look at some Jumpstart instructions... As a n00b to Solaris Administration, I think I am likely to screw that up at the moment. I know that with my FreeBSD system, I specified the RAID at the hardware level then fdisk detected the volume as something I could install to... Last time I

*if* you already have the root filesystem under SVM in the first place, then no reboot should be required to add a mirror. And I assume that's all we're talking about for the ZFS mirroring as well. Is there any reason you'd have SVM on just the one partition? I can see why you'd do
