I still have troubles here. I found out something interesting: I used zero-superblock with --force on the disk and the partition, and i used dd to zero over the end of the partition and disks.
It works now, but when i add the spare-drive to the RAID i get the "error: found two disks with the index 4 for RAID md0." again. When i remove the spare and zero the superblock, it works again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999076 Title: mdadm 0.9 metadata at the end of the disk confuses grub To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/999076/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
