From: Fan Yong <[email protected]> Main part of original patch in Lustre tree (http://review.whamcloud.com/6669) changes server code and is unneeded by client. The patch only picks up common functions and data structures change.
Quoting original commit message here: " OI scrub should has the ability to handle kinds of OI, including both the OI files on MDT and the /O directory on OST. We trust the FID in LMA for both MDT objects and OST objects. So if some /O sub-item does not match related LMA, then the /O will be updated, instead of the LMA. To guarantee that the OI scrub can run without MDT0 involved for FLDB, the OST object needs to store some flag in its LMA to tell OI scrub that it is for an OST object, no need to query the MDT0.
