Replacing ZFS setup - Moving from 6xRAIDz to 4xRAIDz

[Team140]

Currently I have 6 1TB drives in a RAIDz arrangement attached via internal SATA and eSATA 4x enclosure. I want to replace this with a single (new) external USB3 4x enclosure with fresh 2TB drives.

What is the easiest way to accomplish this? This is my first ZFS box and it has done quite well at home, so I'm looking at implementing ZFS at work.

My thoughts are to stand up the new disks and enclosure as a new ZFS pool, copy from ZFS pool to ZFS pool via rsync, tear down original ZFS pool, then export new pool, then re-import as the original pool name.

Does this sound right? Is there an easier method I'm not aware of? The pool name will need to stay the same as there are additional services that rely on that mount point to work correctly.

do not use usb attached hard drives for a nas.

just dont do it.

+1 ; USB is not as robust as SATA, you ave a lot of troubles and at the end lose your data.

Not to mention the drive ordering nightmares of USB... Run away.

I agree, USB 3 may be really fast, but it isn't a replacement for sata.

Sata3 is far better as a standard than USB 3

You are opening a can of worms with USB.

crack open the enclosure. I bet the drives inside are regular SATA drives. Then you can put them in the NAS where they should be.
