This is needed in order to implement OI Scrub for ZFS (which would also allow a file-level backup of an ldiskfs-based MDT/OST to be restored into a newly-formatted ZFS filesystem) and verifying the Lustre namespace metadata (e.g. linkEA and FID-in-dirent).</p> <p>It is also needed for implementing the distributed MDT-OST verification for LFSCK Phase II, and MDT-MDT verification for DNE in LFSCK Phase III.</p> LU-3489
