Bug#380425: mdadm: /etc/cron.d/mdadm doesn't just run on the first Sunday of every month...

Sun Jul 30 05:54:03 UTC 2006

Package: mdadm
Version: 2.5.2-7
Severity: normal

According to man 5 crontab:

"Note: The day of a command's execution can be specified by two fields
-- day of month, and day of  week.   If  both  fields  are restricted 
(i.e., aren't *), the command will be run when either field matches 
the current time.  For example, ``30 4 1,15 * 5'' would cause a command
to be run at 4:30 am on the 1st and 15th of each month, plus every Friday."

Since /etc/cron.d/mdadm says:

6 1 1-7 * 7 root [ -x /usr/share/mdadm/checkarray ] && /usr/share/mdadm/checkarray --cron --all --quiet

I can expect it to run every Sunday, plus the whole first week of the
month. That's a lot more verifying than I need. This is using the
standard debian cron package, 3.0pl1-95. A better choice would be to
pick a day of the month, and run at 1:06 then. Or, have it run every
Sunday, but do nothing if `date +%d` > 7.
