cron job checkarray - checkarray: E: MD subsystem not loaded, or /proc unavailable.

dumalkin · 7. Februar 2021

Hi,

Fresh installation of OMV on PI4, NO RAID whatsoever (2 USB3 external drives are mounted, shared, and everything works as expected).

When monitoring is enabled, I get error messages from periodic cronjob.

The job itself is:

Code

if [ -x /usr/share/mdadm/checkarray ] && [ $(date +%d) -le 7 ]; then /usr/share/mdadm/checkarray --cron --all --idle --quiet; fi

error message is:

Code

checkarray: E: MD subsystem not loaded, or /proc unavailable.

I wholeheartedly agree with the statement "MD subsystem not loaded", as there is no RAID in the system.

Question -

Monitoring system is for RAID only, and it doesn't make sense to activate it without RAID, or I should somehow configure it to skip checking RAID, or what ?

Disable it in the notifications tab, if there is one with the Pi, there is on amd64 installs

I have disabled the notification for "Software Raid", but I still get the notification

"checkarray: E: MD subsystem not loaded, or /proc unavailable"

once a month.

Is there something else I have to do to disable this notification?

Any solutions so far? I recognize the same behavior.

Same me. Receive an email with that error once a month.

Is there really no solution for this annoying issue?

I also got it again (a month later as usual).

The notification is not from OMV but from Debian.

Code

8:15:56 root@hawk:/etc/cron.d# cat mdadm

If you are not using RAID move or delete the file

/etc/cron.d/mdadm

Will it be recreated if one does decide to use raid later? 🤔 could be one of those things one easily forgets about … well maybe rather rename it to .bak at least.

Maybe just comment out the last line in mdadm? I did this today, next month I'll see if it works

Did this work? I am getting the message now.
