zfs discuss - Nov 2008 - Replace Drives in RAIDZ Array

I found this posted on another site and its exactly what I want to do.  I have 6
drives I want to replace with 6 larger drives.  Can anyone help me with what
commands I would need to run?  Do I replace, Offline, etc?

=================2) replace all the drives in the raidz, 1 by 1 (waiting for zfs
to reconstruct the data on the new drive), and when you have replaced the final
drive the zpool will "magically" increase in size. i.e replace the
500GB drives, 1 by 1, with 750GB drives, and when you finish the zpool effective
storage will jump to 2250GB.
=================
thanks,
Chris

Chris,

If you have created a RAIDZ storage pool then yes, you would use zpool
replace to replace the existing disks with the larger disks. See the
example below of a RAIDZ replacement example.

A bug currently exists that means you might have to export and import
the pool to see the expanded disk space.

More device replacement tips are provided here:
