Expanding partitions within a RAID 5 Array

I have a ProLiant ML350 G4 running server 2003 with 4 drives in RAID 5.

The 4th drive in the array was recently added to provide more space. I have completed expansion of the logical drives using the array configuration utility.

I now need to expand the partitions for each logical drive in order to utilize the newly created unallocated space.

I have found out that it is not possible to use disk management to expand partitions on logical drives within a RAID 5 array.

Are there any other possible solutions, which avoid destruction of data and if possible can be used whilst the server is active?

Hi James,

It sounds like you need to use diskpart. Details are here:


Hope this helps,
