[Lustre-discuss] MDT error messages

[Cory Spitz]

Hi.

bz 23615 was from Cray.  I'm checking to see whether we can open that 
bug up or not.  It's a little fuzzy to me now, but it may have been 
related to bz 19934.  If I recall correctly, there was some other root 
cause that was causing stale unlinked orphans to reside on the MDT and 
after we removed the offending objects from the /PENDING directory, the 
problem didn't reoccur.

Thanks,
-Cory
