Default page size in Ignite 2.1 was 2048 (2K), in 2.3 it was increased to 4096 (4K). Since your storage was created on 2.1 with page size of 2K, you need to restore with the same size. To achieve this you should explicitly set DataStorageConfiguration#pageSize property to 2048 when starting Ignite 2.3.
