[lustre-discuss] Problems with quota after adding a new OST

[Mohr Jr, Richard Frank (Rick Mohr)]

Based on the output of your “lfs quota” command, I am not sure that I see a problem with it.  Both active osts (OST0000 and OST0002) and the MDT seem to be returning quota information.   Can you explain what you were expecting to see and how the output differs from your expectations?
