Functional Specification

DIX copy machine provides infrastructure to perform tasks like repair and re-balance using parity de-clustering layout.

Data Structures

• m0_dix_cm Represents DIX copy machine, this embeds generic struct m0_cm and DIX specific copy machine objects.
• m0_dix_cm_iter Represents DIX copy machine data iterator.

Interfaces

Functions to register/deregister DIX copy machine type and corresponding reqh service:

• m0_dix_cm_type_register()
• m0_dix_cm_type_deregister()

Functions to setup, control and fini DIX copy machine:

• m0_dix_cm_prepare();
• m0_dix_cm_stop();
• m0_dix_cm_setup();
• m0_dix_cm_start();
• m0_dix_cm_fini();

Functions to init/fini repair/rebalance trigger fops:

• m0_dix_cm_repair_trigger_fop_init();
• m0_dix_cm_repair_trigger_fop_fini();
• m0_dix_cm_rebalance_trigger_fop_init();
• m0_dix_cm_rebalance_trigger_fop_fini();
