| Description |
|
The MDT-object owner information is trusted over the OST-object’s. Because the chown/chgrp processing order is: client => MDT => OST, it is quite possible that the OST-object owner information is stale rather than the MDT-object’s. Also, the MDT-object’s owner information is visible to users and can be directly repaired by the system administrator, while the OST-object’s owner information is only used internally by quota. So the LFSCK will update the OST-object owner information according to the MDT-object’s owner. |
