First, we created the RAIDZ2 pool zmanda with six drives. Then we added six more drives and verified that we had a pool with 10.9 Tbyte of physical space. Depending on which RAIDZ configuration you choose, the actual available capacity might be different. See the zpool(1M) man page for more details.
