Hard Drive space issue when installing SQL server failover clustering

  • Trying to install SQL server failover clustering on windows server 2008 R2 Enterprise 64 bit using VM ware.

    created clusterdc , node1,node2 virtual machine names on VMware.

    Allocated 15GB hard drive for each .

    After installing windows server 2008 R2 my hard drive got out of space.

    can suggest me how to freeup space ?or how much HD space should i allocate to complete this task?

    Thank you

    you'll need at least 25GB C drive for the Windows 2008 VMs, 40GB ideally. These can be thin provisioned rather than pre allocated. To create the disks manually use the following example

    C:\Program Files\VMware\VMware Server>vmware-vdiskmanager -c -s 25GB -a ide -t 2

    "C:\Virtual Machines\Node1\Node1-C.vmdk"

    This will create a 25GB pre allocated disk using ide adapter called "Node1-C.vmdk" in the path "C:\Virtual Machines\Node1\"

    To create a thin growable disk use -t 0

    To use lsi scsi adapter use -a lsilogic

  • You will be lucky to get the install running on only 25 GB. And if you do then you have no space available for service packs, windows fixes, etc.

    I certainly agree that a system partition size of 40GB is about the optimum size for SQL 2008 R2 on W2008 R2. This should allow you to install 2 or 3 SPs and maybe 12 CUs plus windows fixes over the normal 3 to 4 year lifetime of a server. Expect your 40 GB drive to be near full after this time - SQL Server installs many GB of components in the GAC, which must live on the system drive.
