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.
