| Doc Text: |
Cause: A gear move does not take into consideration the amount of free space available on the node a gear is moved to.
Consequence: Gears could be moved to a node whose free space was less than what the gear required, resulting in gears on that node failing.
Fix: The gear move process now considers the amount of free space on each node when determining which node it should move the gear to.
Result: Gears are no longer moved to a node whose storage speace is not adequate for the gear.
