Good day. I have a 2010 Mac Mini, installed with Snow Leopard Server and configured my HDD with RAID 0. The problem now is, I can't offline my RAID and can't delete my HDDs from the setting. When I select the RAID tab, with the Striped RAID Set, and 2 of my RAID Slice, I can't select the '-' button. Whenever I also click Delete, I get a 'Deleting RAID set failed' error. Also whenever I erase the individual HDDs or remove the it from the partition, I also get a 'Partition failed. POSIX reports: The operation couldn't be completed. Resource busy' error. Is there a way to fix this problem? Thanks.
