== sanity-lfsck test 28: Skip the failed MDT(s) when handle orphan MDT-objects ========================================================== 06:17:37 (1713521857)
#####
The target name entry is lost. The LFSCK should insert the
orphan MDT-object under .lustre/lost+found/MDTxxxx. But if
the MDT (on which the orphan MDT-object resides) has ever
failed to respond some name entry verification during the
first stage-scanning, then the LFSCK should skip to handle
orphan MDT-object on this MDT. But other MDTs should not
be affected.
#####
Inject failure stub on MDT0 to simulate the case that
d1/a1's name entry will be removed, but the d1/a1's object
and its linkEA are kept in the system. And the case that
d2/a2's name entry will be removed, but the d2/a2's object
and its linkEA are kept in the system.
