mdadm: sending ioctl [1261|800c0910] to a partition!

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi everyone,

I was wondering what the following kernel messages mean in plain English

sending ioctl 1261 to a partition! 

and

mdadm: sending ioctl 800c0910 to a partition!

Oh, and this as well

scsi_verify_blk_ioctl: 52 callbacks suppressed

What would it tell me, if I read this technical language? The exclamation mark is a bit alarming, and as for suppressed callbacks I have no idea whether it is something I should be paying attention to or not.

Could anyone, please, comment on this?

Ivan
