Unable to restore data to recreated NSS volume.

When attempting to add space to an NSS volume by deleting the current one, recreating a larger one with the same name, then restoring data to the volume will result in an not enough space error. The space that the volume occupied also shows as used in NSSMU. A poolrebuild will clear the free space.

This is working as designed. NSS has the capability of salvaging deleted volumes. The default length of time is 4 days. The following parameters can be changed to clean up deleted volumes quicker if desired. A poolrebuild cleans up the space as it doesn't deal with salvageable volumes on the pool.

The following NSS commands control this feature:
nss /LogicalVolumePurgeDelay= Seconds to delay logical volume purging after delete. [Value=345600] = 4 days
nss /LogicalVolumePurgeDelayAfterContinue= Seconds to delay logical volume purging after a continue. [Value=900]= 15 minutes
nss /LogicalVolumePurgeDelayAfterLoad= Seconds to delay logical volume purging after NSS load. [Value=7200] = 120 minutes

nss /LVDeleteStatusBasic Displays information about deleted logical volumes
nss /LVDeleteStatusSalvageable Displays information about salvageable logical
