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

A mechanism exists that will prevent certain activities on a StorageServer from filling up disk space once a 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
