If you are trying to delete MDT0000 then that is definitely not implemented yet...<br>

<p>Hi,</p>
<p> I'm running some lab tests with lustre 2.12.2 in Oracle Linux Server release 7.6. Last test I did was about migration and MDT splitting. I started with a MGS+MDS node, and two OSS nodes, and one of the tests was to create two more MDSs and migrate
data between then, until, after some time, I could delete the original MDS. But something happened in the middle and the servers panicked/rebooted.<br>
</p>
<p> I am now in what appears to be an lfsck bug. After many other tests, I run lfsck_start, and after some time get this message on the nodes:</p>
<p>MGS/MDS0:</p>

<p> Is this a known bug? How do I fix these "partial" lsfck runs?<br>
</p>
<p> Thanks for any help,</p>
