RAID Events in mdadm
1 At a terminal console, log in as the
root
user.
2 Edit the
/etc/mdadm/mdadm.conf
file to add your e-mail address for receiving alerts. For
example, specify the MAILADDR value (using your own e-mail address, of course):
DEVICE partitions
ARRAY /dev/md0 level=raid1 num-devices=2

devices=/dev/sdb3,/dev/sdc3

Alert
Description
Device Disappeared No An
md
array that was previously configured appears to no longer be
configured. (syslog priority: Critical)
If mdadm was told to monitor an array which is RAID0 or Linear, then
it will report DeviceDisappeared with the extra information Wrong-
Level. This is because RAID0 and Linear do not support the device-
failed, hot-spare and resynchronize operations that are monitored.
Rebuild Started No An
md
array started reconstruction. (syslog priority: Warning)
Rebuild NN No Where NN is 20, 40, 60, or 80. This indicates the percent completed
for the rebuild. (syslog priority: Warning)
Rebuild Finished No An
md
array that was rebuilding is no longer rebuilding, either
because it finished normally or was aborted. (syslog priority:
Warning)
Fail Yes An active component device of an array has been marked as faulty.
(syslog priority: Critical)
Fail Spare Yes A spare component device that was being rebuilt to replace a faulty
device has failed. (syslog priority: Critical)
Spare Active No A spare component device which was being rebuilt to replace a faulty
device has been successfully rebuilt and has been made active.
(syslog priority: Info)
New Array No A new md array has been detected in the /proc/mdstat file.
(syslog priority: Info)
Degraded Array Yes A newly noticed array appears to be degraded. This message is not
generated when
mdadm
notices a drive failure that causes
degradation. It is generated only when
mdadm
notices that an array is
degraded when it first sees the array. (syslog priority: Critical)
Move Spare No A spare drive has been moved from one array in a spare-group to
another to allow a failed drive to be replaced. (syslog priority: Info)
Spares Missing Yes The
mdadm.conf
file indicates that an array should have a certain
number of spare devices, but
mdadm
detects that the array has fewer
than this number when it first sees the array. (syslog priority:
Warning)
Test Message Yes An array was found at startup, and the
--test
flag was given.
(syslog priority: Info)
