As far as I know there is no question here: you simply cannot put 4K drives in a vdev originally created with 512b drives[*]. You need to make a new pool with the 4K drives. Even if you could get them into the existing pool, the performance effects would likely be relatively bad. ZFS does a lot of unaligned writes. - cks [*: If we're being technical, it's possible to force OmniOS to think that they're all 512b drives. ] _______________________________________________ OmniOS-discuss mailing list OmniOS-discuss@lists.omniti.com http://lists.omniti.com/mailman/listinfo/omnios-discuss
