I have set up mdadm raid 1 on 2 disks fine and have got the test emails working using
mdadm --monitor --test --oneshot --scan
My config is at /etc/config/mdadm
and I have run /etc/init.d/mdadm enable
and on reboot everything works as expected. Great.
But what I haven’t worked out is whether I need to specify anything in the config so that I will get emailed if anything goes wrong with a disk. ie. in the config do I have to specify MONITOR anywhere or is it already assumed?
(or) Is there another method like running a second mdadm process with the --monitor flag that is required?
