[asterisk-users] Saftware RAID1 or Hardware RAID1 with Asterisk

[Steve Totaro]

I guess I am just lucky to have 24 hour manned data centers with staff 
that walk around looking for flashing LEDs.

I am sure there is some error thrown in /var/log/messages about a 
failure that could be used to trigger a notification quite trivially.

Thanks,
Steve
