Bug#679719: mdadm monthly cron job should NOT check all arays at the same time

Package: mdadm
Version: 3.1.4-1+8efb9d1+squeeze1
Severity: normal
I have deleted -- after finding through pain it existed -- the monthly mdadm cron job in cron.d.
the problem is that this cron job will cause ALL raid's to be checked at the same time, causing a potentially very high I/O load. In my particular case with 2 RAID 6 and 2 RAID 5 it causes an I/O load that will overload the link between the CPU and the expansion cabinet. This WILL result in a number of disks being kicked from arrays, as they cannot answer in time. As it is not predictable which disks will be kicked, this can cause data loss resulting in the need to recover from backup.
I have written a script in cron.daily what will cause each raid to be checked weekly, and never more then 1 at the same time.
I am aware that in a profesional environment this problem should not occur. For home/small business users though a setup like mine is well usable. BUT care must be taken that the I/O rate remains within limites. And checking all raid at the same time can cause very significant
The currently running recovery on the 2 raid 6 is causing an io load of about 1500 - 1600 tps.
I have not checked what the limit is. Doing a "check" on all 4 raid is clearly over the limit though.
