988 - Storage Platform API: StorageServer soft limits for disk usage

A mechanism exists that will prevent certian activities on a StorageServer from filling up disk space once the threshold has been reached.

The limit is determined by the StorageVolumeMinFreeSpaceGB setting.

Viewing the setting

The setting StorageVolumeMinFreeSpaceGB can be viewed using the Storage Platform API:

https://<accountserver>/api/system/settings
(A default value of 1GB is used)

Changing the setting

To set a different value (to 5GB for example), also use the API URL:

https://<accountserver>/api/system/settings?StorageVolumeMinFreeSpaceGB=5
