How FlexCache volumes use space management

FlexCache volumes do not use space management in the same manner as regular FlexVol volumes. The amount of disk space reserved for a FlexCache volume is determined by the value of the flexcache_min_reserved volume option, rather than the nominal size of the FlexCache volume.

The default value for the flexcache_min_reserved volume option is 100 MB. In general, you should not change the value of this option.

Attention: FlexCache volumes’ space guarantees must be honored. When you take a FlexCache volume offline, the space allocated for the FlexCache becomes available for use by other volumes in the aggregate (as with all FlexVol volumes). However, unlike regular FlexVol volumes, FlexCache volumes cannot be brought online if there is insufficient space in the aggregate to honor their space guarantee.
