Going from 1 vdev 2 disks mirrored to 2 devs each 2 disks mirrored is pretty straight forward. Attach initial two disks as a mirror vdev: zpool attach zones c0t0d0 c0d1t0 Add third and fourth disks as a mirror vdev: zpool add zones mirror c0t2d0 c0t3d0 http://blog.alainodea.com/en/article/448/making-a-zfs-4-disk-mirrored-vdev-zpool-on-smartos-on-r720xd I'm not sure what the best process for disk replacement is, but I've done very limited autogrowth experiments and it looks like you can replace disks in a mirror vdev one at a time with larger and wait for resilver and continue: http://blog.alainodea.com/en/article/440/experiments-with-zfs-failure-modes-and-autogrowth Best, Alain -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJTta3lAAoJEP0rIXJNjNSAapcH/0Knb4g5KBhggTmRBuyxuTWT O9sk4qq+SO51mt/ZMbw6sSe+6pZ4F8s3MP9p5RjtwJkcip98uOxb23pY4aJdd4P4 IitCTYMSr0cgwURq2HJvIjO5wQS3l33yWdiZUckifKSvEqhZoC6oAIcbyq/o3Jl1 PgyFP2LFuLYswrakTYzJHlFNJ+XLVm7W1OtUYjk06hU5THcdY1EmbyCBGyzaL6Rl CqWPYK3b/aYtptkz8gQLTtFsLoqBkdL1gt6qucw5mV5o7JzOyZQWA0bjIfFHnWgr 05LOF2r/kokjD71rOUErtKa09XWqkTdAtutAEHuUjaeNi0GwNmDiOyTvC9mPuuA= =0qY0 -----END PGP SIGNATURE----- ------------------------------------------- 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
