Low and high watermarks determine when to begin and stop automatic purging of deleted files to free up space on the pool. You configure thresholds for space-based purging on each pool. NSS automatically purges the deleted files and directories for all volumes in the pool with a first deleted, first purged policy until the free space reaches the high watermark, or until all of the existing deleted directories and files are purged, whichever occurs first. The pool’s Low Salvage Watermark setting is reached, indicating that the amount of free space is below the administrator-specified minimum. For information, see Section 24.2.1, Setting the Purge Delay for All Deleted Volumes. The server-level LogicalVolumePurgeDelay parameter applies to all NSS volumes. The elapsed time between the delete and the purge is called the purge delay. Autopurging begins automatically and can take some time, depending on the size of the volume. The Logical Volume Purge Delay setting times out for a deleted volume. Table 24-2 describes parameters that control the file-system salvage behavior for NSS volumes. The administrator user or any user who is a trustee with the Create right can salvage deleted directories and files. Deleted directories and files are retained and can be salvaged until space is needed in the pool where the volume resides, as determined by the pool’s available-space watermark settings. You can enable the Salvage attribute when you create the volume, or modify the setting later in the volume’s properties. Salvage for directories and files is controlled by each volume’s Salvage attribute. Therefore, the volume is purged at 7:39:06 p.m. The latest time is considered for auto purging. LogicalVolumePurgeAfterLoad: 7:20:00 p.m. LogicalVolumePurgeAfterContinue: 7:39:06 p.m. For example, you have deleted a volume and set the following parameters for auto purging: The auto purging of logical volumes is determined by all the above mentioned volume salvage parameters.
