Description blakawk 2012-03-14 09:52:38 UTC 
In order to fix a security vulnerability, a patch was applied in the kernel that disallow some IOCTL to be sent to a partition (see kernel commit 0bfc96cb77224736dfa35c3c555d37b3646ef35e). This leads to a printk message 'mdadm: sending ioctl 1261 to a partition' each time mdadm is trying to access details about a RAID array.

Reproducible: Always

Steps to Reproduce:
1. mdadm --details <any RAID array>
Actual Results:  
Message 'mdadm: sending ioctl 1261 to a partition!' in dmesg.

Expected Results:  
No message.

Comment 3 SpanKY gentoo-dev 2012-11-11 08:19:51 UTC 
i don't see this with mdadm 3.2.6.  but i'm not using a partitioned raid.

please post the output of the --detail command that is triggering the warning.
