Informing the Operating System of Changed Configuration

After you change the configuration of a unit, you must inform the operating system of the change, and you may need to re-partition the unit.

Resizing the file system to match the new partition size is not automatic. It may be necessary to expand the file-system using tools specific to your operating system.

In addition, in order to use the new capacity, you need to either resize the existing partition or add a new partition.

To inform the operating system that secondary storage has been upgraded

If you change the configuration of the boot unit (the unit containing the operating system), you must reboot the system in order to see the new unit capacity.

Unmount all file systems.

Under Windows, go to Start > Administrative Tools > Computer Management, and select Disk Management. Remove the logical drive letter for the unit.

Under Linux and FreeBSD, from a command prompt, type sync <enter>, sync <enter>, sync <enter>.

You can then unmount the unit with this command: umount <mount location>

If the reconfigured unit is secondary storage, you must have the controller rescan, in order to update unit information.

In 3DM2, select the appropriate unit and choose Management > Maintenance. Click the Remove Unit button.

After the unit has been removed, click the Rescan button. The new unit capacity displays.

Resize the partition and file system or create a new partition.

In Windows, use the disk management utility to determine whether the disk is a basic disk or a dynamic disk.

Go to Administrative Tools > Computer Management, and then select Disk Management in the list on the left.

Only dynamic disks can be expanded with Windows Disk Management. If the unit is shown as a basic disk, you must either convert it to a dynamic disk or use a 3rd party tool to rubrication the unit.

If the unit is shown as a dynamic disk, right-click on it and choose Extend Volume to launch the Extend Volume wizard.

In Linux and FreeBSD, the tools to expand the partition and file system can vary, depending on the kernel version and file system that you are using. Please consult your Linux/FreeBSD documentation and the 3ware Knowledgebase for more information.
