Making sure that a filer has enough remaining disk space available is critical for several reasons:
| • | SAN administrators want to make sure to be able to provision disk space for new servers and users when requested, as quickly as possible. |
| • | The filer itself may need additional disk space for specific features to work properly, like automatic snapshots, mirroring, etc. |
| • | Users and applications actively using a share on the filer will surely be severely impacted by the fatal "File system is full" error message |
The disk space used is permanently monitored for each aggregate and each volume with the SEN_NAP_7|C_AGGREGATE, SEN_NAP_7|C_VOLUME and SEN_NAP_C_NODE_ROOTVOLUME application classes.
