Friendly advice: you can force this 512e drive into an existing 512n pool. However, you will be unhappy with the performance of the result. You will be happier with a 512e device. > > the other models in the ZRAID are a Seagate ST31500341AS (1,5TB) which > reports as 512 and seems just to have 512 > dkmp_ext.dki_lbsize = 512 > dkmp_ext.dki_pbsize = 512 > > and the same is reported by the other Western Digital 1TB WD10EADS > > I do not think that there is a way that the old ones will work with 4K, but I > hope that the new one will work with 512. And I really hope that someone has > the clue how to integrate my new diskdrive before another one dies… I think you’ve got this backwards? 512n devices work fine with 4k block sizes. 512e drives perform poorly with 512 byte block sizes. — richard > > Mat > -- [email protected] +1-760-896-4422 ------------------------------------------- smartos-discuss Archives: https://www.listbox.com/member/archive/184463/=now RSS Feed: https://www.listbox.com/member/archive/rss/184463/25769125-55cfbc00 Modify Your Subscription: https://www.listbox.com/member/?member_id=25769125&id_secret=25769125-7688e9fb Powered by Listbox: http://www.listbox.com
