[lustre-discuss] Error in lfsck: "NOT IMPLEMETED YET"

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:
24107:0:(osd_index.c:1872:osd_index_it_get()) NOT IMPLEMETED YET (move
to 0x2481000002000000)*
OSS1/MDS1
*[Mon Jul 22 17:40:29 2019] LustreError:

OST2/MDS2

0xa013000003000000)***
And for current lfsck status, I run *lctl get_param *.*.lfsck* |
grep -E 'status|\.lfsck_lay|\.lfsck_name'*
MGS/MDS0:
*mdd.mirror01-MDT0000.lfsck_layout=**

**status: partial*

*mdd.mirror01-MDT0001.lfsck_layout=**
**status: completed**
**mdd.mirror01-MDT0001.lfsck_namespace=**

**obdfilter.mirror01-OST0065.lfsck_layout=**

OST2/MDS2
*mdd.mirror01-MDT0002.lfsck_layout=**
**status: completed**
**mdd.mirror01-MDT0002.lfsck_namespace=**
**status: partial**
**obdfilter.mirror01-OST0066.lfsck_layout=**
**status: completed*
Is this a known bug? How do I fix these "partial" lsfck runs?
Thanks for any help,
Jonny
