struct m0_pdclust_tgt_addr	ftc_tgt
struct m0_pdclust_src_addr	ftc_src

Detailed Description

Represents a cell of a fault tolerant tile stored in m0_pool_version. Base tile provides an implicit mapping between (parity group, unit) and (target, frame). The fault tolerant tile stores two values within every cell:

• (target, frame) to which a pair (parity group, unit), that would have otherwise belonged to current cell in the base tile, is moved to.
• (parity group, unit) that is stored in the current cell.
