[dm-devel] RAID status, CSMI, and dmRAID

[Sandra Escandor]

Hello,

 

I've recently been researching the issue of obtaining RAID status on
Linux (using a library or API, not through scripts). I've read that CSMI
codes can be issued (using ioctl() calls) to get RAID status, and from
my understanding (please correct me if I'm wrong), dmraid doesn't use
CSMI at all, and the status is obtained using the metadata on the member
drives. Does this mean that using CSMI and ioctl is not possible on
Linux, or does this mean that using CSMI and ioctl is a bad idea on
Linux?

 

Thanks for the clarification,

Sandra
