[Lustre-discuss] Data corruption?

[Nirmal Seenu]

Could someone help me understand what the following error messages mean:

When I do a "ls -l" I get ? in all the fields but for the filename on 
some of the files:

?--------- ? ?     ?            ?            ? cart_wengen.odd_even.txt

I recently moved the MDT to a different partition. I performed a lfsck 
on the the file system and got these errors from lfsck:

/aa/bb/cc/dd/xx/cosmology.c object 8024 not created

I keep getting the following error message on all the OSTs:
Mar 27 08:21:57 lustre2 kernel: LustreError: 
6886:0:(ldlm_resource.c:858:ldlm_resource_add()) lvbo_init failed for
  resource 301930: rc -2

TIA
