This topic describes how to manage free and allocated space.
You can use the storage pool usage threshold and the fileset quota and usage threshold to manage the storage space in SAN File System.
The storage pool usage threshold is a percentage of the storage pool's estimated storage capacity. When the amount of used space reaches or exceeds the specified threshold, the metadata server generates an alert.
The fileset quota is the size limit, in megabytes, for the fileset. When the size of the fileset reaches or exceeds the specified limit, the metadata server generates an alert. You can specify either a hard or soft quota. A hard quota denies requests for additional space, and a soft quota grants requests space allocation.
The fileset usage threshold is a percentage of the fileset's quota. When the amount of used space reaches or exceeds the specified threshold, the metadata server generates an alert.
