How to re-convert Raid0 to Raid5?

Our MSA500 G2 has a RAID5 on 5 300GB Disk + 1 300GB spare, ARRAY1!

In this ARRAY1 is a logical drive with ca. 1144407 MB!

Yesterday I accidentally convert the RAID5 to RAID0! This action ends without problems and everything is fine at present.

Now I have a logical drive with size of ca. 1144407 MB and free disk space of ca. 286 101 MB.

What should I do to re-convert the RAID0 to RAID5 without loosing data und without downtime?

If I start config-assistant and choose RAID5 to reconfigure the logical drive, I became a message that sometimes the data will be deleted, if no logical drive is configured on ARRAY1!
But there is a logical drive!

Is that the right procedure to get back the RAID5?

best regards

Sebastian

You should be able to migrate the logical unit from RAID 0 to RAID 5 as there's space for the parity data.
Please post the exact message you get when doing this.
