what use is it if one disk fails… and half of the swap area goes lost and you can not resync the disks because some system-processes are failing….
# switch off swap space swapoff -a # check out what software raid to switch off cat /etc/mdadm/mdadm.conf # switch it off mdadm --stop /dev/md/2 # remove it mdadm --remove /dev/md2 mdadm --zero-superblock /dev/sda5 mdadm --zero-superblock /dev/sdb5 # recreate it mdadm --create /dev/md/2 --level=1 --raid-devices=2 /dev/sda5 /dev/sdb5 # save config mdadm --detail --scan >> /etc/mdadm/mdadm.conf # reactivate swap space mkswap /dev/md/2 swapon /dev/md/2 # Watch them resync and wait until complete. watch cat /proc/mdstat
