Following ingest, if an ILM rule’s Content Placement instructions are configured to make replicated copies of object data, copies are made and stored to disk through the LDR services of Storage Nodes that make up the configured storage pool.
The table shows the primary attributes used to track a replicated object:
Component | Attribute changes |
---|---|
ILM Evaluations (ILev): The total number of ILM evaluations that have been performed to date increases when the object is evaluated after ingest and again when a copy of object data is made.
Note: The number of evaluations is dependent on the StorageGRID Webscale system’s ILM rules.
Total Transfers (DCdT): The total number of object transfers performed by the CMS service since system start-up increases by one each time a copy of object data is made. |
|
Total Usable Space (STAS): The total amount of object storage space that is currently available to be used to store objects decreases by an amount roughly equivalent to the object’s size. Total Usable Space (Percent) (SAVP): The total amount of object storage space (displayed as a percentage) that is currently available to be used to store objects decreases by an amount roughly equivalent to the object’s size. Total Persistent Data (Percent) (SPSD): The estimate of the size of the persistently stored data increases by an amount roughly equivalent to the object’s size. Total Persistent Data (Percent) (SPDP): The percentage of the total storage space used by persistent data on each destination LDR service increases by an amount roughly equivalent to the size of the replicated object. Objects Retrieved (ORET): The number of persistent objects retrieved from the source LDR service increases by one. Objects Committed (OCOM): The number of persistent objects stored on each destination LDR service increases by one each time a replicated copy is made. |

destination | Inbound Replications Completed (RIRC): The total number of objects replicated to the destination LDR service increases by one. |
source | Outbound Replications Completed (RORC): The total number of objects replicated from the source LDR service increases by one. |
