I suggest you partition the disks with a small (10-20 GB?) partition (slice to some) for rpool and the rest of the disk in another partition. Mirror the rpools and build a RAIDZ2 on the big partition. You'll get more usable space and two disk failure tolerance.
If you *really* want to be efficient with 6 disks, use a three way rpool mirror and make a RAIDZ1 for log files using the other 3 partitions. Single disk failure tolerance on everything and two disk tolerance on the critical bits. It may not be "bootable RAIDZ" but it's close enough in my book. It gets the job done w/ minimum effort and good failure tolerance for the cost. True bootable RAIDZ would not look much different from an operations perspective. In fact, it might be more complicated. The really nice thing about partitioning the disk like this is how simple it is to set up. -------------------------------------------- On Wed, 2/26/14, Stefan Müller-Wilken <[email protected]> wrote: Subject: [OpenIndiana-discuss] ZFS pool layout - request for opinion To: "[email protected]" <[email protected]> Date: Wednesday, February 26, 2014, 2:06 AM Dear all, one thing I stumble over again and again is ZFS pool layout for 6 disk servers (e.g. 1 HU ProLiants) . What I do so far is reserving disk 1 & 2 for the rpool mirror and put disks 3 - 6 into a RAIDZ-1 data pool. I don't really like this layout as it means wasting a lot of space on the rpool while having only minimal redundancy for data. What do others do to combine space efficiency with bootability and redundancy?
