ENDIT daemons 1.3.0
This release is a bugfix and improvement release:
- tsmdeleter now queues deletes to periodically process them, this batches deletes that trickles in over a longer time period which improves the efficiency of tape space reclamation.
- NOTE that this means that the tape pools now have state for deleted files as well, see the README for details on pool decommission etc.
- tsmtapehints now respects the
ENDIT_RETRIEVER_HINTFILEenvironment variable to override the hintfile location. - tsmarchiver now spawns multiple single-drive sessions instead of a single session with varying resource usage. This works around weird corner cases where activity halts pending resources such as a tape drive becoming available. This also allows a quicker reaction to load change, and a better threshold based strategy better adapts to incoming data rate.
- A side effect of this is obsoleting the configuration options archiver_threshold[1-9]_dsmcopts. They can simply be removed from your configuration.
- The tsmretriever is now aware the extended metadata produced by newer ENDIT dCache plugin versions, and doesn't try to spawn restores for archive session data.
In addition to this are assorted smaller fixes. The complete list of changes since the last release can be viewed on the GitHub compare page
