It is prudent to set up email notifications that alert you when a RAID is in a degraded state. For a Software RAID on Linux (/dev/md partitions) this is done as follows. (Note: instructions are specific to OpenSuSE.)

  1. Go to YaST -> System -> /etc/sysconfig editor
  2. Within the sysconfig editor, select: System -> File systems -> Mdadm
  3. Set MDADM_MAIL (for OpenSuSE 13.1 this can be a comma-separated list, for OpenSuSE 11.1 it must be a single email address)
  4. Set MDADM_SEND_MAIL_ON_START to 'yes'
  5. Click 'Ok' and quit YaST
  6. From the command line do 
    insserv mdadmd
/etc/rc.d/mdadmd start
  7. You should receive a test email for each raid partition.
