S == spare. Recreate md0 like this: mdadm --create /dev/md0 -l 1 -n 2 /dev/sdb3 missing This creates a RAID1 device with 2 disks, but it's created in *degraded mode*. Now when add sda3 later, md0 will resync as expected. Ensure you have backed up your data before playing with mdadm!! - Raja _______________________________________________ To unsubscribe, email [email protected] with "unsubscribe <password> <address>" in the subject or body of the message. http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
