[lustre-discuss] problem with one orphan

[Hebenstreit, Michael]

I've got an orphan problem  - this process on the combined mds/mgs is running at 100%

   PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
  5902 root      20   0       0      0      0 R 100.0  0.0 974:22.49 orph_lfs11-MDD0

And I literally got millions of dmesg entries

[56994.471189] LustreError: 5902:0:(mdd_orphans.c:324:mdd_orphan_destroy()) lfs11-MDD0000: could not delete orphan [0x2000043a7:0xf03:0x0]: rc = -2

[58194.438033] LustreError: 5902:0:(mdd_orphans.c:324:mdd_orphan_destroy()) Skipped 36973695 previous similar messages

any suggestion how I can get rid of this ONE orphan?

Thanks
Michael
