    Raid 5

    I have a Raid 5 with 3 disks using O/S W2003 Server
    I want to add a 4th disk to the raid but cannot see how to do so using the W2K3 software.
    The disk is the same size as the others and has been converted to dynamic.
    Please can you help
    Thank you

    Regards

    Duncan

    Re: Raid 5

    Is this a hardware or a software controlled array?

    The Windows Server 2003 family of operating systems provides software-based RAID, where the creation and regeneration of redundant information on the disks in the RAID-5 volume is handled by the Logical Disk Manager (LDM). In this case, you cannot add disks to a RAID-5 volume if you need to increase the size of the volume later. You must destroy and rebuilt the entire array to do so.

    Some hardware-based RAID controllers allow you to add disks, for example, Compaq ProLiant family servers.

    Re: Raid 5

    The raid is software generated using the LDM of Server 2003
    The disks are all SATA2
    I suspected the LDM to be restrictive and prevent additions

    Thanks and regards
