How to extend a VA scratch disk and retain the data on the disk (video) (4047054)

After running out of space on the scratch disk, the scratch disk is extended. However, the available space shown by the Linux df command is unchanged.

When a virtual appliance scratch disk is enlarged, the usable space is unchanged because the file system is not extended to fill the available space. If you replace the scratch disk with a larger disk, the file system will fill the disk, but the old contents are lost so the the VM disks must be rehashed before they can replicate.
