[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: 
31558:0:(osd_index.c:1872:osd_index_it_get()) NOT IMPLEMETED YET (move 
to 0xa41300c002000000)*

OST2/MDS2

*[Mon Jul 22 17:40:32 2019] LustreError: 
8935:0:(osd_index.c:1872:osd_index_it_get()) NOT IMPLEMETED YET (move to 
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: completed**
**mdd.mirror01-MDT0000.lfsck_namespace=**
**status: partial*

OSS1/MDS1

*mdd.mirror01-MDT0001.lfsck_layout=**
**status: completed**
**mdd.mirror01-MDT0001.lfsck_namespace=**
**status: partial**
**obdfilter.mirror01-OST0065.lfsck_layout=**
**status: completed*

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
