Hi,
I recently moved a server from old disks to now ones and added a hotspare (mdadm /dev/md1 -a /dev/sdf2)
the hotspare appears in /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5] [multipath] [raid6]
md1 : active raid5 sdf2[5] sde2[4] sdd2[3] sdc2[2] sdb2[1] sda2[0]
285699584 blocks level 5, 64k chunk, algorithm 2 [5/5] [UUUUU]
when I fail a disk, mdadm does *not* send me any warning.
Only at the second failure when the array is in degraded state I receive a warning.
How may I receive a warning when the hotspare disk has been used to cope with a disk failure?
Thanks

From the mdamd man page:
Only Fail , FailSpare , DegradedArray , and TestMessage cause Email to be
sent.
Your event is "SpareActive" which does not trigger an alert mail,
however all events can be reported through the "--program" switch:
All events cause the program to be run. The program is run with
two or three arguments, they being the event name, the array
device and possibly a second device.
Only at the second failure when the array is in degraded state I receive
a warning.

--program "my_mail_script.sh"
#!/bin/sh
nail -s "$1 event detected on device $2 $3" root < EOF
Dear admin,
You array seems to have suffered to breakage:
A $1 event was received on for device $2 $3.
Fix it ASAP!
Regards,
EOF
