All, please advice. I''m trying to start Lustre with next configuration (1 - MDS, 2 - OTS, 3 - OTS). 2 and 3 OTSs started properly, however when I start MDS server I have the following in the messages logs: Apr 11 17:18:22 foma kernel: Lustre: 4139:0:(lib-move.c:1644:lnet_parse_put()) Dropping PUT from 12345-0@lo portal 6 match 75 offset 0 length 240: 2 Apr 11 17:18:22 foma kernel: Lustre: 4139:0:(lib-move.c:1644:lnet_parse_put()) Skipped 1 previous similar message Apr 11 17:18:27 foma kernel: LustreError: 4139:0:(client.c:940:ptlrpc_expire_one_request()) @@@ timeout (sent at 1176301102, 5s ago) req@c6a67c00 x75/t0 o8->ost4-test_UUID@klava_UUID:6 lens 240/272 ref 1 fl Rpc:/0/0 rc 0/0 Apr 11 17:18:27 foma kernel: LustreError: 4139:0:(client.c:940:ptlrpc_expire_one_request()) Skipped 1 previous similar message System configs: Linux susen 2.6.16-27-0.6_lustre.1.4.9bigsmp #1 SMP SUSE Enterprise 10 on all boxes.
