How mdadm checks periodically the array in Debian 13 Trixie?

[Franco Martelli <martellif67@gmail.com>]

Hello,

I noticed that the file "/etc/cron.d/mdadm" is missing in the "mdadm" 
package in Trixie. This file checked monthly the array of disks of the 
RAID set, and it was there in all previous Debian stable releases.

Today at 2pm I resumed from suspend to RAM my PC and suddenly an array 
checks of my RAID 5 set was started, so the questions are:

- Which rules "mdadm" now follows to start an array check?
- Is it safe to copy "/etc/cron.d/mdadm" file from Bookworm to Trixie?

Thanks in advance, kind regards.
