mdadm --monitor in rc.local

Hi everyone,

I've been here in the past, I hope you'll be able to help as my many searches on the Internet didn't get me the right answer.
I have a RAID5 array built with mdadm.
I've configured mailx and msmtp to be able to receive message (from smartmontools and mdadm).
When I try the command I put in rc.local it works.

mdadm --monitor --scan --daemonise --delay 120 --test

This works when I use it with sudo.
And when I do:

sudo /etc/rc.local

It works too.
Here are the permissions on the file:

-rwxr-xr-x 1 root root 138 Aug 19 19:27 /etc/rc.local

But when I boot the machine, nothing is sent (I used the --test command, so it HAS to send a test email when run)

Kind regards,

Naunaud.

Re: mdadm --monitor in rc.local

Perhaps it requires an application of raid params using mkinitcpio as outlined in the wiki to enable mdadm during boot sequence.

I am not sure of your apps however so I could be way off in no man's land!!

Re: mdadm --monitor in rc.local

Well, the RAID5 is only for storage, the system is on another disk outside the RAID, so I'm not sure what you're talking about. I've read the wiki:
http://wiki.archlinux.org/index.php/Con … Using_raid

Is that what you're referring to ?

And as rc.local is the last script run on the machin before any login, I was hoping it would work.

Kind regards,

Naunaud.

Mmm, now that I'm thinking about it, could it be that the mailing functions are not available by the time of the rc.local run ?

Kind regards,

Naunaud.

Re: mdadm --monitor in rc.local

rc.local is run last, so network etc should all be up an running (unless you're using something like NetworkManager in your DE to manage the network of course).

Any reason you're doing this in rc.local instead of using the daemon designed for this? (/etc/rc.d/mdadm)

Well, if I launch the daemon with rc.conf, it doesn't seem to monitor anything...
When I set a drive faulty, there's no email report.

Is there another tool to monitor a RAID created with mdadm ?

Re: mdadm --monitor in rc.local

Have you setup /etc/mdadm.conf? The daemon works for me after I configure that:

MAILADDR my_email_address@gmail.com
ARRAY /dev/md0 level=raid1 num-devices=2 metadata=0.90 UUID=46649049:2fe1a3ab:d28dda9b:ac5154d8
ARRAY /dev/md1 level=raid1 num-devices=2 metadata=0.90 UUID=817f74b4:7a3fddc2:9c15dca4:e5d40b5e
ARRAY /dev/md2 level=raid1 num-devices=2 metadata=0.90 UUID=e2f167e5:8097e2b8:38f93247:422d0e7b

Has it ever send you a mail in case of failure ?
(and yes my mdadm is configured like that)
I'll just put the daemon in rc.conf then and wait for a real failure!

Kind regards,

Naunaud.

Re: mdadm --monitor in rc.local

Yes, I used to get email regularly when I had faulty RAM locking the computer, which would cause mdadm to rebuild after a hot-reset
