This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig0402EA43580307E3D2299BAA Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hi, folks, Currently we have a RAIDZ1 system using 6 x 1TB drives, which we use as a bacula storage device. We now have another 6 x 1TB drives to increase capacity. I'd originally planned to just create another zpool and have two partitions mounted for bacula to store stuff in. However, it would be better in many ways if we could just add the capacity to the existing setup, presumably by creating a second vdev in the original pool. However, according to my understanding, if you want to boot from a zpool, you can only have one vdev in that pool. But what exactly does this mean? Is it really mounting the root fs that's the problem, or is it reading the kernel out of /boot ? Originally I followed the recipe in http://wiki.freebsd.org/RootOnZFS/GPTZFSBoot/RAIDZ1 for creating a system using a RAIDZ1 pool, so I have small freebsd-boot and -swap partitions on every drive. I don't really need that much swap space, so is there a way of parlaying that into something like the UFS /boot setup described in http://wiki.freebsd.org/RootOnZFS/UFSBoot ? Except I don't care about BIOS level compatibility with other OSes and so would happily forgo installing a MBR.
