Hi there,<br>
I have a stupid problem, but i really can't find a solution on
internet. I attempted to mount a client from the wrong IP address
(the routing table was not correct, my bad). The mount failed due to
NAT, but the client was able to contact the MDS. Now that I fixed
the route I got the following error:<br>

I know a way to fix this is to use tunefs.lustre but I have to
shutdown the whole cluster to do that. I guess there must be a way
to be able to mount this client ignoring logs without the need to
delete log for the entire cluster.<br>
<br>
This is with lustre 2.1.1<br>
<br>
Thank you for the help. Please CC me ( <a class="moz-txt-link-abbreviated" href="mailto:tagliavini@fbk.eu">tagliavini@fbk.eu</a> ) to the
