I then added it into the array and it worked as before. However, it still wasn't added when I rebooted. ...but, there is something different. Now, when I --examine /dev/sdi, it gives output for the whole array including 2 spares, which is the end result I expect : Active Devices : 6 Working Devices : 8 Failed Devices : 0 Spare Devices : 2 However, --detail /dev/md2 still denies /dev/sdi exists : Active Devices : 6 Working Devices : 7 Failed Devices : 0 Spare Devices : 1 What's up?
