Hi Andres, For general ZFS best practices info, please see this site:
http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide For your specific questions, creating a mirrored ZFS configuration provides the most flexibility if you want to change the device configuration. For example, you could start with a two-way mirror, like this: # zpool create tank mirror c1t0d0 c2t0d0 Then, attach another disk for a 3-way mirror: # zpool attach tank c2t0d0 c3t0d0 If you get more disks, add another 3-way mirror: # zpool add tank mirror c3t0d0 c4t0d0 c5t0d0 Even better, add some spares: # zpool add tank spare c2t1d0 c3t1d0 If you change you mind, go back to two, 2-way mirrors: # zpool detach tank c3t0d0 # zpool detach tank c5t0d0 If you want to replace the existing disks, with larger disks, then: # zpool replace tank c1t0d0 c6t0d0 and so on, until all the disks are replaced. Similar examples are available in the ZFS Administration Guide: http://docs.sun.com/app/docs/doc/817-2271/gavwn?a=view You cannot currently remove a device except to replace a disk in a mirrored or RAIDZ configuration, or detach a disk in a mirrored configuration.
