1010 * the OI file, related OI mapping is unknown yet, please try again later. And
1011 * then client will re-try the RPC again and again until related OI mapping has
1012 * been updated. That is quite inefficient.
1014 * To resolve above trouble, we will handle it as the following two cases:
1016 * 1) The slave MDT-object and the master MDT-object are on different MDTs.
1017 * It is relative easy. Be as one of remote MDT-objects, the slave MDT-object
1018 * is linked under /REMOTE_PARENT_DIR with the name of its FID string.
1019 * We can locate the slave MDT-object via lookup the /REMOTE_PARENT_DIR
1020 * directly. Please check osd_fid_lookup().
1022 * 2) The slave MDT-object and the master MDT-object reside on the same MDT.
1023 * Under such case, during lookup the master MDT-object, we will lookup the
1024 * slave MDT-object via readdir against the master MDT-object, because the
1025 * slave MDT-objects information are stored as sub-directories with the name
1026 * "${FID}:${index}". Then when find the local slave MDT-object, its OI
1027 * mapping will be recorded. Then subsequent osd_fid_lookup() will know
1028 * the correct OI mapping for the slave MDT-object.
