If you are trying to delete MDT0000 then that is definitely not

No, no, no...
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).
I will later try to migrate to another server, and then delete MDT2.
But first I need to finish this lfsck... :-(
These "NOT IMPLEMETED (sic)" messages are just from running lfsck_start -A

Hi,
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.
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:
MGS/MDS0:
*[Mon Jul 22 17:42:25 2019] LustreError:

And for current lfsck status, I run *lctl get_param *.*.lfsck* |
grep -E 'status|\.lfsck_lay|\.lfsck_name'*

**obdfilter.mirror01-OST0066.lfsck_layout=**

Is this a known bug? How do I fix these "partial" lsfck runs?
Thanks for any help,
Jonny
