You should not need to wipe the disk. mdadm is smart enough to use Update Time and Event count to determine that the disk is not the current disk and needs rebuilding.
mdadm (actually kernel driver) is not smart at all. If you boot with single array member and modify file system, then with another single array member and modify file system differently and finally with both members together it will happily assume both belong to clean array and are synchronized - causing data corruption. Just got it trying to reproduce this issue. @stakanov - could you please show mdadm --examine /dev/sdc1 mdadm --examine /dev/sdd1 before doing any changes? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
