I couldn't get the clue if a fsck would help now or not. Andreas Dillinger wrote about 2 years ago: """I'm not sure why this bug was closed. The patch for b2_1 was still not landed, and the work to rebuild the OI files in LFSCK Phase 4 is not completed.""" But I couldn't get if that statement is only for Lustre-2.1 or general.
