(SOLVED) Strange parity check behaviour

[DivideBy0]

I have a parity check scheduled every 3 months.  It started normal and finished without any errors but to find out the next day that parity check is running again.  I didn't manually start the second one, nor the system rebooted. Could it be a bug or something else?

See attached diagnostic file

So both of unraids performed the same way which is strange. I have a schedule setup for every 3 months.  The November one kicked normally and as per my initial post the second unraid started a second parity check out of nowhere.  As I was monitoring the first unraid to finish the scheduled parity check and I noticed after it finished, the schedule show to start another scheduled parity check in 2 hours.  That's very strange. So something messed up with the schedule?  I disabled and redone the schedule again and hope this won't happen again?

 

Anyone seen this strange parity schedule behavior?

Was end of daylight savings time involved?

Thank you Sir.  How do I check that please?  It could I guess

[trurl]

Did daylight saving time end in your location?

Yes indeed, that could be it.  It ended first Sunday of Nov for CST

First Sunday of Nov hasn't happened yet, Sunday was Oct 31. In US we don't fall back until this coming Sunday Nov 7, 2AM.

Doooh So what was it then?  The strangest thing and it happened on both of my unraids which have same schedule.

What do you get from the command line with this?

cat /etc/cron.d/root

Is that a custom entry? (I see it is) When did you set this up? Seems like it would have been running every day in Oct.

Correct, is custom and is every 3 months or so.

Not what that entry says   it means run it every day during the 3 selected months.    You need to constrain it to a specified day within those 3 months.

As noted, it is every day on 3 specific months
