Adjustment of garbage collection parameters in a storage system

A non-transitory machine-readable medium having stored thereon instructions for performing garbage collection in a distributed storage system, comprising machine executable code which when executed by at least one machine, causes the machine to:

• monitor a set of filters corresponding to a set of slice services, the set of slice services residing in a cluster and including a set of content identifiers, and the set of filters indicating whether a set of data blocks referenced by the set of content identifiers is in-use;
• determine whether a false-positive rate for the set of slice services satisfies a performance threshold;
• adjust the false-positive rate of at least one filter of the set of filters in response to determining that the false-positive rate satisfies the performance threshold;
• and
• performing garbage collection on the set of data blocks in accordance with the set of filters.

A computing device comprising:

• a memory containing a machine-readable medium comprising machine executable code having stored thereon instructions for performing garbage collection in a distributed storage system;
• and
• a processor coupled to the memory, the processor configured to execute the machine executable code to:
• for each round of garbage collection:
• monitor an efficiency level of a garbage collection process for a set of data blocks referenced by a set of content identifiers, the set of data blocks residing in a cluster, and a set of filters indicating whether the set of data blocks is in-use;
• determine whether the efficiency level is below an efficiency threshold;
• reduce a false-positive rate of a filter of the set of filters;
• and
• perform garbage collection on the set of data blocks in accordance with the set of filters.
