Please note that we released 1.6.7.1 shortly after 1.6.7 in order to address
a MDS corruption which was bug 18695.

This really looks like you are hitting bug 18695. I would really recommend
upgrading to 1.6.7.2 or 1.8.2. Please note that your MDS can be severely
damaged by bug 18695, so you should run e2fsck against the MDT device before
upgrading.
