Recently I decided to upgrade my old linux based hdd enclosure: processor arm9 kernel 2.6.12 I can't update or upgrade linux or it's kernel So I tried to update HDDs: When I run this command I realized that I need linear, not raid0 mdadm -Cv /dev/md0 --level=0 -n2 /dev/sda2 /dev/sdb but when I tried to zero superblocks (I stopped md0 previously) I've got "Segmentation fault" error.. Later I have connected my drives to PC and zeroed superblocks sucessfully, but when I connected drives back to enclosure and tried to create linear I've got "Segmentation fault" error again! And from now every time I'm trying to do something via mdadm with these drives I'm getting that "Segmentation fault" error! I haven't tried dd if=/dev/zero of=/dev/sda2 cause my hard drive have 2Tb! Here are my questions: 1. Can mdadm damage my hard drive(s)? 2. How to locate and zero superblocks completely? (I know that there are two versions of superblocks.. but I don't know which one I have) Thanks -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
