mdadm: no more mails during monthly scrubbing under Jessie

mdadm: no more mails during monthly scrubbing under Jessie

[Hans Kraus]

Hi,

I recently upgrades my Debian sever from Wheezy to Jessie.

I have the standard configuration, especially the monthly ckeck via the
cron entry: "57 0 * * 0 root if [ -x /usr/share/mdadm/checkarray ] &&
[ $(date +\%d) -le 7 ]; then /usr/share/mdadm/checkarray --cron --all
--idle --quiet; fi".

Under Wheezy I got progress mails like:
-------------------------------------------------------------------------
MD Device: /dev/md/robbe:storage
Event: Rebuild60

/proc/mdstat:
Personalities : [raid6] [raid5] [raid4]
md127 : active raid6 sdk1[0] sde1[9] sdi1[8] sdf[7] sdj1[5] sdg1[4] sdh1[6]
       19534426880 blocks super 1.2 level 6, 128k chunk, algorithm 2 
[7/7] [UUUUUUU]
       [============>........]  check = 60.9% (2381950248/3906885376) 
finish=259.5min speed=97924K/sec
       Action ready: 2016-04-03 12:13:13.949761

unused devices: <none>
-------------------------------------------------------------------------
from mdadm system.

I do not get these mails any more. Extensive googling brought nothing
except some users complaining about theese mails ...

How do I enable theese mails again? I like them as security info that
all is well with my Raid.

Kind regards,
Hans

You would probably be better off asking on a Debian help list, or open a
Debian bug.  This is a configuration specific to Debian.

I suspect the email was generated by running "mdadm --monitor" and
providing it with a program to run on every event.  The program would
have sent the emails.

I only have sid installed and it doesn't seem to provide any such
script.
There is something in /usr/share/doc/mdadm/examples but the script there
doesn't send emails.
