Detecting array parameters

[Piergiorgio Sartor <piergiorgio.sartor@nexgo.de>]

Hi,

if I understood it correctly, in order to detect
the several array parameters (number of disks, for
example), it is possible to use "mdadm -D /dev/mdX"
or to check the files in the corresponding /sys/block/...
/mdX/... files.

Now, assuming something needs to be done in scripts,
what would be the best way? Using "mdadm -D ... | grep"
(or "mdadm ... | gawk ...."), or to read the proper
files in /sys/block/md...?

Assuming the wanted information is available on both
sides, which does not seem always the case.

Thanks,

bye,
