[lustre-discuss] lfsck namespace doesn't stop and I cancel it

[Fernando Perez]

Seems that there is a problem with a fid.

When I run:

lctl get_param -n mdd.lustre-MDT0000.lfsck_namespace

The lfsck current position is always the same. The position is a folder 
with some files, and when I try to delete it the lustre client hangs...

I think that this is the origin of the lfsck problem.

How can I remove this fid / file?
