Faulty drive/degraded state doesn't trigger anything

[Hyrla]

Hello,

I setup this wonderful plugin successfully. However, there is not alerts triggered even if I manually set a disk to faulty state.

My Zabbix Agent is used in passive mode so I just changed "Zabbix Agent (active)" to "Zabbix Agent" in discovery templates settings.

Here's the output of few debug commands :

su -c 'zabbix_agentd -t rabe.raid.md.raid-device.discovery' -s /bin/bash zabbix
rabe.raid.md.raid-device.discovery [t|{"data":[{"{#MD_RAID_RAID_DEV_NAME}":"md0"}]}]

mdadm -D /dev/md0

Am I doing anything wrong ?

Thank you :)

Is the array showing up as degraded in /sys/block/md0/md/degraded?

[Hyrla]

@hairmare yes it is, this file exists and its content is "1"

@paraenggu PTAL

@Hyrla sorry for the late reply, I overlooked this one.

A degraded drive should at least fire two triggers:

• RAID array device MD {#MD_RAID_RAID_DEV_NAME} has {ITEM.VALUE1} degraded device(s) on {HOST.NAME}
• RAID component device MD {#MD_RAID_RAID_DEV_NAME} RD {#MD_RAID_COMPONENT_DEV_NAME} is in {ITEM.VALUE1} state on {HOST.NAME}

In your case above:

• RAID array device MD md0 has 1 degraded device(s) on {HOST.NAME}
• RAID component device MD md0 RD satab1 is in faulty state on {HOST.NAME}

Cloud you please post the relevant latest values of the affected host?
