Which version of mdadm are you using? I have 3.0, and defalut metadata |
15 |
is 0.90: |

|
17 |
-e , --metadata= |

Declare the style of RAID metadata (superblock) to be used. The |
19 |
default is 0.90 for --create, and to guess for other operations. |
20 |
The default can be overridden by setting the metadata value for |
21 |
the CREATE keyword in mdadm.conf. |

BTW [1] says about kernel 2.6.9, things might have changed since then... |
