    Matrix Raid with different disk sizes, how to use the capacity that is unassigned to Raid array ?

    mitch.net

      Hi all,

       

      I started using Intel Matrix Raid with a 2*400Gb Raid-0 Volume.

      What I had

      HDD1

      400GB

      HDD2

      400GB

      Raid-0

      800GB

      400GB400GB

       

      Now I added 2 new 1Tb disks and expanded the Raid-0 volume to these new drives so I get a Raid-0 Volume of 4*400Gb=1600Gb, thanks to intel matrix storage manager for the expansion feature. I expanded my Raid-0 volume as wanted.

       

      But I also wanted to use the space left on the 2 1Tb drives (600Gb left on each disk) to create a Raid-1 on 2 disks but I didn't find a way to perform this.

       

      Summary of the solution I planned to do:

      what I planned

      to do

      400GB

      HDD3

      1000GB

      HDD4

      1000GB

      Raid-0

      1600GB

      400GB400GB400GB400GB

      Raid-1

      600GB

      600GB600GB

       

      But, in Intel Matrix Storage Manager it shows that I have 1 Array of 1600Gb capacity with the Raid-0 volume taking all this space, and all 4 disks attached to this array. I cannot create a new volume because the array is full and they are no more disks wich are not already attached to an array.

       

      As I didn't managed to perform this solution I get:

      what I have

      up to now

      HDD1

      400GB

      HDD2

      400GB

      HDD3

      1000GB

      HDD4

      1000GB

      Raid-0

      1600GB

      400GB400GB400GB400GB

      Unused capacity

      1200GB

      600GB600GB

       

      My question is: how can I use the 600Gb unassigned capacity of my 1Tb disks that are not used by the raid array ? (either creating another raid array for raid-1, or just having access as stand-alone drives, or whatever solution allowing me to use this unassigned capacity)
