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

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?
