I've created a RAID1 array in LVM (lvcreate -m1 --type raid1....). The system is unattended, so I would now like a notification email if one of the disks fail. I could probably write a cron job to continually check the status of the volume. However, this seems like basic functionality for a raid array.
What is the best way to monitor an unattended LVM RAID or mirror? The only choices for raid_fault_policy in lvm.conf are warn (log) and allocate. Sendmail is already setup and working.
