Just install the OS on the first drive and add the second drive to form a mirror. There are wikis and blogs on how to add the second drive to form an rpool mirror. After more than a year or so of experience with ZFS on drive constrained systems, I am convinced that it is a really good idea to keep the root pool and the data pools separate. AFAIK you could set up two slices on each disk and mirror the results. But actually I'm not sure why you shouldn't use your USB drive for root pool idea. If it breaks you simply reinstall (or restore it from a snapshot on your data pool after booting from a CD). I suppose you could mirror the USB drive, too, but if you can stand the downtime after a failure, that probably isn't necessary. Of course, SSDs are getting pretty cheap in bootable sizes and will probably last forever if you don't swap to them, and that would be an even better solution. USB SSD thumb drives seem to be quite cheap these days. The you'd have a full-disk mirrored data pool and a fast bootable OS pool; if you go the SSD route I'd go for at least 32GB. Of course you could get a 1TB USB drive to boot from, and use it to keep a backup of the data pool, but if it failed, you'd be SOL until you replaced it. IMO that would be the best 3-disk solution.

Re: [zfs-discuss] Is LSI SAS3081E-R suitable for a ZFS NAS ?
I do not know if this has anything to do with some of the problems you're seeing. however, there is definitely an issue using /some/ LSI controllers on Supermicro boards. I just rencetly had an issue with using LSI3442 (the next gen over the 1068E chipset) on a Supermicro MB (X8DTN-6). Anyhow, if the LSI board is in the system, the drives are recognized and everything works. HOWEVER, if you have to use the SATA CD-rom/DVD drive - it will not boot from the drive. For whatever strange reason, supermico and I determined that it just didn't like the LSI SAS Controller in the system which caused this. We have no idea why a SAS controller would affect a SATA boot. . . Another issue we have found is the latest x8dtn board does not play nice with the latest release of Solaris (at least for us). It will work fine up to snx129. However 131 (or upgrading from 129 to 131) will fail on boot after GRUB. It'll just cycle/reboot at that stage over and over. Not sure what the issue is between 129 and 131 but that is what we've found on our Supermicro MB and the latest OpenSolaris version. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
