Increase the disk space in vCenter Server Appliance (2056764)

Details

VMware vCenter Server Appliance with an embedded vPostgres database might experience low disk space.

Solution

To increase the disk space available:  
  1.  Shut down the vCenter Server Appliance.
  2. Add a new hard disk of necessary size to the vCenter Server Appliance. 

    For more information on adding a new hard disk, see:

  3. Power on the vCenter Server Appliance.
  4. Connect to the vCenter Server Appliance using SSH.
  5. List all disk and identify the device ID of the new disk added by running this command in the shell client:

    fdisk -lu

    Note: By default, the device ID for the new disk is /dev/sdc

  6. Access the disk utility for the new disk by running this command:

    fdisk /dev/sdc

    1. Press  N then Enter for new partition
    2. Press  P then Enter for primary partition
    3. Enter  1 as the partition number
    4. Accept the default start block and the default end block
    5. Enter  W to write the partition table to disk
    6. Create a new partition on the new disk:

  7. Build an ext3 file system on the new disk using this command:

    mkfs -t ext3 /dev/sdc1

  8. Create a new temporary directory under the root directory by running this command:

    mkdir /tmp/db

  9. Mount the new disk to the /tmp/db directory by running this command:

    mount -t ext3 /dev/sdc1 /tmp/db

  10. Power off all services that access the vPostgres /storage/db directory by running this commands:

    service vmware-vpxd stop
    service vmware-vpostgres stop
    service vmdird stop
    service vmware-inventoryservice stop

  11. Copy all the /storage/db files into the /tmp/db directory by running this command:

    cp -a /storage/db/* /tmp/db

  12. Return to the root directory by running this command: 

    cd /

  13. Unmount the original disk and the new disk by running this commands:

    umount /dev/sdb3
    umount /dev/sdc1


  14. Mount the new disk to the /storage/db directory by running this command:

    mount -t ext3 /dev/sdc1 /storage/db

  15. Preserve the new mount to the /storage/db directory by running the command:

    sed -i -e 's#/dev/sdb3#/dev/sdc1#' /etc/fstab

  16. Reboot the vCenter Server Appliance.
