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

<p>No, no, no...</p>

<p>This was my first idea, but then I understood that the root
directory is always on MDT0, so I had to migrate it to another
server (after having created two more, and crashed during
migration).</p>

MDT2. But first I need to finish this lfsck... :-(</p>

<p>These "NOT IMPLEMETED (sic)" messages are just from running
lfsck_start -A<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>
