Bug#598957: checkarray: I: selecting idle I/O scheduling class for resync of md0

Package: mdadm
Version: 3.1.4-1+8efb9d1
Severity: important

Hi,

the checkarray cronjob mailed me these lines:

checkarray: I: selecting idle I/O scheduling class for resync of md0.
checkarray: I: selecting idle I/O scheduling class for resync of md1.

I believe that this is "normal", so this really shouldn't be mailed to me.

Thanks,
Christian
