<p class="MsoNormal"><span style="font-size:11.0pt;font-family:Calibri">Running "e2fsck --mdsdb" will take _much_ longer than a regular e2fsck, because the mdsdb database is sparsely written. I would recommend not running the old e2fsprogs-based lfsck, since
Lustre 2.5 has enough functionality to repair the Lustre-specific parts of the local filesystem (after a regular e2fsck), and Lustre 2.7 will also fix the MDT-OST consistency (orphan objects and dangling MDT layout references).<o:p></o:p></span></p>
