Backup fails after smartdisk is reported as full but smartdisk is not full (4046499)

Date: OCT 2010
Product & Version: SmartDisk 1.2
OS Version: all
Symptoms:
Smart disk has more than 1 volume allocated to it but the majority of data written goes to just the one volume.
We see the backup stall and sometime fail due to smart disk reporting that its full in the binary log as seen bleow

When using the following command we see smartdisk balancing set to "Activity."

smartdisk config --show

Cause:
The "Activity" option does not seem to be working as expected.

cd to the smartdisk/foundation/bin and Set the smartdisk balancing option to shared using the following commands:

smartdisk config --update --volume <path> --balancing space

Windows example:
smartdisk config --update --volume "C:\ NetVault SmartDisk\store" --Balancing space
Configuration applied

smartdisk config --update --volume "C:\ NetVault SmartDisk\diskmanager\stage" --Balancing space
Configuration applied

Unix example:

smartdisk config --update --volume /mnt/smartdisk/store --Balancing space
smartdisk config --update --volume /mnt/smartdisk/stage --Balancing space


Note: this will need to be done on all volumes and both staging and stored locations, so check that the option has been changed on all volume after making changes.
