The existing vdev (the first set of disks) is still there and he added another vdev (a second set of disks, in raidz2 configuration) to the pool. So, the pool is certainly bigger. > I think that the word is that you can't > change the geometry of a created raidz. That's not fully true. You can replace every disk in vdev (mirror, raidz, raidz2) by a bigger one, one by one, resilvering after every replacement, and grow the existing vdev, thus growing the pool while keeping hte same configuration. -- ( Kees Nuyt ) c[_] _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
