SCSI Unmap Enhancement
SCSI Unmap is a FluidFS attribute that controls the way deleted file space is handled. When disabled, the SCSI Unmap setting
will keep deleted file storage within the FluidFS storage pool. This means that when files are deleted, their storage pages remain
“used” for the Storage Center management tools. When SCSI Unmap is enabled, deleting files also frees the storage pages at
the block level and the storage will be marked as white space and able to be utilized by the Storage Center system for other
block clients. SCSI unmap is now enabled by default when installing a new appliance.
SCSI unmap is now enabled by default when installing a new appliance.
NOTE:
If you have any systems that were deployed using a version earlier than 6.0.300135,ensure that SCSI Unmap had
been enabled to prevent unnecessary space from being consumed.
