Description
During LFSCK layout reconstruction, it may rebuild a corrupted LOV EA on the MDT based only on the trusted.fid information stored on each OST object. The client will need to pass a flag to the OST objects (e.g. during EC writes) to mark them as EC parity and not regular data.
LFSCK in turn needs to check trusted.fid for this flag on the OST objects, and so that the rebuilt MDS layout rebuild process marks the reconstructed component/EC mirror with LOV_PATTERN_PARITY and not use it as a regular data mirror after LFSCK rebuilds the layout.
