Abstract
Disclosed are a data migration method, system and device for a storage server, and a non-transitory readable storage medium. The method includes: according to storage information of a storage server, determining the number n of strips to be migrated; selecting n stripes to be migrated from among c full stripes according to a preset migration rule, and selecting, from the n stripes to be migrated, data blocks to be migrated and migrating the data blocks to the newly inserted disks, so that after the migration is completed, the difference in stripe usage between any two disks in the storage server does not exceed 1; and determining data content of check data blocks of the strips so as to complete data migration of the storage server, and determining data content of check data blocks of the c-n strips by means of incremental update of an erasure code.
