[Ocfs2-devel] OCFS2 errors in log EVEN just after FSCK

[vde at ykoctpa.ru]

There is 2-node cluster with master-master DRBD and OCFS2 filesystem, kernel 
4.0.4

Some time ago I found such errors in log (on both nodes)

and so on. FSCK (ocfs2_tools 1.8.4) every time found and fix lots of "orphaned 
cluster" errors but after mount this starts again.

in namei.c I found that this starts from ocfs2_find_entry  - so there is some 
filesystem errors leaved even after fsck
