update mdadm version to 3.3.2 in Centos 6.4

[alpha lin]

Hi All,

    I would like to know the possibility of update the mdadm package
from 3.2.5 to 3.3.2 in Redhat Centos 6.4 x64 system.
    The problem I have is I found that I can create a raid volume
without any problem. But when reboot the system. The md volume become
inactive.
    Below is my step:
    1. Check out mdadm package from the github.
    2. unzip the mdadm package and execute "make" and "make install"
    3. reboot.
    4. after system reboot, run mdadm to create a imsm RAID Volume.

Fwd: update mdadm version to 3.3.2 in Centos 6.4

[alpha lin]

Forgot to mention that my Centos 6.4 x64 system has upgrade kernel to 3.16.0.
So the failure is base on kernel 3.16.0

Any reason why you haven't upgraded to centos 6.6? 6.4 is ancient, and
6.6 will at least come with mdadm-3.3.

Hi Jes,

   I have my Oracle database running on Centos 6.4. There will be
great if I can stay in  Centos 6.4 rather than upgrade to Centos 6.6.

Alpha.
