I cannot confirm that; instead I am assuming a workflow like the following: 1. A disk is about to fail 2. Notification from SMART hits sysadmin's mailbox 3. # swapoff /dev/sdXY 4. Replace disk, create partitions 5. # swapon /dev/sdXY 6. # mdadm /dev/mdK -a /dev/sdXZ -- Michael Iatrou -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
