I took a dedicated server in the cloud. Delivered hardware raid 10 to it. Why mdadm?

Question

linux

I took a dedicated server in the cloud. Delivered hardware raid 10 to it. But after installation I find

43 2 16 * * root if [ -x /usr/share/mdadm/checkarray ]; then /usr/share/mdadm/checkarray --cron --all --idle --quiet; fi

Answer 1

It simply means that you have the mdadm package installed. If you don't have arrays created by mdadm there, nothing will be checked. Those. you can just ignore it.
Well, the server has nothing to do with the cloud, nevertheless, probably. =)

Answer 2

Option 2. Either you still have a software raid array, or it's just default in Hetzner's image. Just check /proc/mdstat.
