Hi I have a couple of questions I currently have a 4disk RaidZ1 setup and want to move to a RaidZ2 4x2TB = RaidZ1 (tank) My current plan is to setup 8x1.5TB in a RAIDZ2 and migrate the data from the tank vdev over. What''s the best way to accomplish this with minimal disruption? I have seen the zfs send / receive commands which seem to be what I should be using? The reason I''m not doing a simple copy is I have Xen Volumes as well which I''m not exactly sure how to copy over. ZFS list (snipping the rpool) yields tank tank/vm tank/vm/centos48 tank/vm/centos48/disk0 tank/vm/centos54 tank/vm/centos54/disk0 Basically I''m looking to replace a 4disk Raidz1 with an 8disk raidz2 (from what I understand I can''t simply add 4 more disks to the existing raidz1 and update it to raidz2) -- This message posted from opensolaris.org

You will end up with a clone of your original pool''s filesystems on the new pool. -- Ian.
