migrate raid 1 to 2x raid 0

[BorysJ]

I want to get more space by splitting RAID1 into independent RAID0. There is no risk to safety, because data is duplicated on 2 servers. Ideally I would like to keep contents of 1st disk directly and have second unused, to create another volume. Last resort is to delete RAID1, make new RAID0 and let it rebuild overtime. Servers are DL380G9 with P440ar

Just split the mirror using the Smart Storage Administrator GUI and reformat the remaining logical disk.
