Linux Commands - mdadm --detail (show details of RAID array)

Updated:   |  Linux Commands articles

The mdadm command with the --detail flag can be used to display the details of a RAID array.

mdadm --detail /dev/md0

 

Something like this should be returned.

/dev/md0:
           Version : 1.2
        Raid Level : raid0
     Total Devices : 1
       Persistence : Superblock is persistent

             State : inactive
   Working Devices : 1

              Name : www.example.com:root
              UUID : db6713ad:66881ca7:48e01e17:6f0a0053
            Events : 209562

    Number   Major   Minor   RaidDevice

       -       8       17        -        /dev/sdb1

 

Likewise, the mdstat file can be read.

cat /proc/mdstat

 

Which should return something like this.

Personalities :
md127 : inactive sdb1[0](S)
      1930428416 blocks super 1.2

unused devices: <none>
