Zusammenfassung: | The invention relates to a GC method of a distributed all-flash object storage system, electronic equipment and a storage medium. The GC method comprises the following steps: dividing all SSDs into a plurality of EC groups to be stored in a plurality of volumes according to an EC proportion of the distributed all-flash object storage system; writing data, binding each bucket with a different volume, and aggregating and writing the data of each bucket into the volume according to a time sequence; a GC real-time program is executed, a database is inquired, the information of a volume where a deleted object is located is counted, the processing progress is recorded, and the volume information comprises the data deletion amount in the volume, the effective data amount in the volume and the erasing frequency of the volume; a GC migration program is executed, a database is inquired, and volume information counted by a GC real-time program is obtained; effective data are migrated according to the volume information, |
