[lustre-discuss] Lnet errors

[Alastair Basden]

Hi,

Lustre 2.12.2.

We are seeing lots of errors on the servers such as:
Oct  5 11:16:48 oss04 kernel: LNetError: 6414:0:(lib-move.c:2955:lnet_resend_pending_msgs_locked()) Error sending PUT to 12345-172.19.171.15 at o2ib1: -125
Oct  5 11:16:48 oss04 kernel: LustreError: 6414:0:(events.c:450:server_bulk_callback()) event type 5, status -125, desc ffff8fe066bb9400

and
Oct  4 14:59:48 oss04 kernel: LustreError: 6383:0:(events.c:305:request_in_callback()) event type 2, status -103, service ost_io

and
Oct  5 11:18:06 oss04 kernel: LustreError: 6388:0:(events.c:305:request_in_callback()) event type 2, status -5, service ost_io
Oct  5 11:18:06 oss04 kernel: LNet: 6412:0:(o2iblnd_cb.c:413:kiblnd_handle_rx()) PUT_NACK from 172.19.171.15 at o2ib1

and on the clients:
m7: Oct  5 14:46:59 m7132 kernel: LustreError: 2466:0:(events.c:200:client_bulk_callback()) event type 2, status -103, desc ffff9a251fc14400

and
m7: Oct  5 11:18:34 m7086 kernel: LustreError: 2495:0:(events.c:200:client_bulk_callback()) event type 2, status -5, desc ffff9a39ad668000

Does anyone have any ideas about what could be causing this?

Thanks,
Alastair.
