Hi All,<br>
<br>
After the recent power glitch last week one of our lustre file systems<br>
failed to come up.<br>
<br>
We diagnosed the problem down to a file system error on the MDT. This<br>
is an old IEEL systems running on Dell equipment.<br>
<br>
Here are the facts...<br>
<br>
* the raid 6 array running on an Dell MD32xx is ok.<br>
<br>
* when we bring up the MDT it goes read-only then the MDS host crashes<br>
<br>
* after this the MDT file system is dirty and we have to e2fsck it<br>
<br>
* I have tried multiple combinations of MDS up/down, OSS up/down with<br>
nothing changing the results.<br>
<br>
* This seems to be lustre 2.7.15<br>
<br>
I think this may be<br>
<br>
<a href="https://jira.whamcloud.com/browse/LU-7045" rel="noreferrer" target="_blank">https://jira.whamcloud.com/browse/LU-7045</a><br>
<br>
or something like that.<br>
<br>
Is there a way to LFSCK (or something) this error away? Or is this a<br>
please update lustre error.<br>
<br>
Thanks for any help.<br>
<br>
I have attached the error below.<br>
<br>
Thanks for any insight,<br>
<br>
sb. Scott Blomquist<br>
