Last night I created a raidz1 array, however later in the evening I realised I needed to create a raidz2 (RAID5), is it possible to change the raid level of my array from raidz1 to raidz2 without destroying the data on the drives?

Welcome to Ask Ubuntu! How did you set up ZFS on Ubuntu Linux? This is not a Linux native file system. I know of an external project and a FUSE approach. – gertvdijk Jan 16 '13 at 9:59
I used this tutorial: – Magnum26 Jan 20 '13 at 12:57
Please edit your question with extra information. This is a Q&A site, rather than a discussion forum. Also, your link is basically just a blog and not a single how-to. Based on the blog contents I believe you used this ZFS-native PPA. Please also incorporate more of your set up, (pool set up, disks, etc.). Keep in mind that ZFS is not a Ubuntu/Linux file system, so it will be hard to get support here. If you don't get response here, consider asking it on instead where more ZFS-people are active. – gertvdijk Jan 20 '13 at 13:46
That is correct I did install the ZFS syetem using the ppa, I then created a zpool with my disks 3 x 1TB. Last night I destroyed the Raidz0+1 and created a RaidZ2 as I couldn't find a solution. I'm now copying over the data again. – Magnum26 Jan 21 '13 at 9:29

Rebuilt the array using RaidZ2 instead as I couldn't see a way of changing it over.

Thanks anyway.
