Thanks martysch. That is what I meant about adding disks to vdevs - not adding disks to vdevs but adding vdevs to pools.
If the geometry of the vdevs should ideally be the same, it would make sense to buy one more disk now and have a 7 disk raid-z2 to start with, then buy disks as and when and create a further 7 disk raid-z2 leaving the 15th disk as a hot spare. Would 'only' give 10TB usable though. The only thing though I seem to remember reading that adding vdevs to pools way after the creation of the pool and data had been written to it, that things aren't spread evenly - is that right? So it might actually make sense to buy all the disks now and start fresh with the final build. Starting with only 6 disks would leave growth for another 6 disk raid-z2 (to keep matching geometry) leaving 3 disks spare which is not ideal. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
