[LU-3837] problem of run old lfsck on DNE

Tue, 29 Oct 2013 16:40:41 +0000

From Andreas:

Finally, I'm also concerned that if the old lfsck is run on a DNE filesystem with multiple MDTs and/or OSTs with FID-on-OST enabled, it is going to do completely the wrong thing, possibly deleting a large number of "unused" objects that are not referenced by MDT0000.
At a minimum, a check should be added to old lfsck to refuse to run if it finds signs of DNE (e.g. O/seq, seq > 2) on the OSTs.
