Some time ago, I attempted to upgrade a RAID 1 array to a RAID 10 array by adding two more disks to the original two that lived in an IBM xSeries 346. In the RAID card's bios, I told it to grow the array onto the new disks, and for whatever brain-glitch reason I checked the "striped" box. This just striped the old RAID 1 array across the new disks without upgrading it to RAID 10. The RAID card reports that the RAID level is "1E".
Naturally, I was quite dismayed to find that the array was no bigger than when I started.
Is there any way I can fix this? Can I pull the new drives (with the intention of formatting them and starting the upgrade again) without destroying the array?
