[Lustre-discuss] WARNING: Potential directory corruptions on the MDS with 1.6.7

[Peter Jones]

A bug has been identified in 1.6.7 that can cause directory corruptions 
on the MDT. A patch and full details are in bug 18695 - 
https://bugzilla.lustre.org/show_bug.cgi?id=18695

We recommend to anyone running 1.6.7 on the MDS to unmount the MDT, run 
e2fsck against the MDT device and apply the patch from bug 18695 as soon 
as possible.

Please note that the landing that caused the regression was that for 
11063, so anyone running with that patch on an earlier 1.6.x release 
should also follow the above procedure.

This fix will be included in 1.8.0 and we will also create an ad hoc 
1.6.7.1 release to provide this fix as soon as possible. 1.6.7 will be 
withdrawn from the Sun Download Center
