I realize u work on 2.11 future rel. This post not related to Soak, but looking at the Log it appears striped sets giving timeout problem.. May i ask why not use IB RDMA? i plan a 8-node running 2.10 Lustre with IB connect.. i wish to hold the DB in-memory..distrib across nodes. What is the best installation using Mellanox ConnectX2 VPI 40Gb / node in pure IB thru a SX6036 switch. These methods need integration within Lustre .. At What stage ? Is the WQE encapsulated inside the PCIe doorbell and written via Programmed IO? Or is the WQE fetched in a separate DMA read by the HCA? Main issue, how does Lustre map to in-mem distributed store? Even on a 2 node split using only ConnectX2 VPI (dual port) or X3 (but i hear IB performance is slower on X3). New features of Lustre 10 makes local routing a breeze direct from the header. dont wish for this MPI issue to dominate : (even tho not using MPI directly) Can u say if MPI libraries are used at all in Lustre , or affected UDP binaries, in the case i use UDP) ? Is IB datagram mode available as DMA (or other layer) transport within Lustre 10 ? MPI IP performance is affected by the socket-buffer sizes for sending and receiving UDP data. These are defined by two network tuning parameters udp_sendspace and udp_recvspace. When the buffer for sending data is too small and quickly becomes full, UDP data transfer can be delayed. When the buffer for receiving data is too small, incoming UDP data can be dropped due to insufficient buffer space, resulting in send-side retransmission and very poor performance. Heres v2 of Mellan Ib utils : Worth the ask, if Sarah or other may interest in remote install / Dev onto a NY cluster.. on a casual basis. |

The attached Lustre debug log indicates that during the mount process, Client is fetching the soaked-client config LLOG from MGS and running the different config steps according to its content.

the forked LLOG parser thread for the soak-client config, PID 2519 should be the LNet discovery thread, PIDs 2508/2510 should be ko2iblnd scheduler threads. Looks like there is a race between LNet discovery thread bottom handling of ACK for previous sent PUT msg to 192.168.1.110@o2ib, and 2510/ko2iblnd scheduler thread handling consecutive "stale" (unexpected or due to multi-rail?) PUT msg received from 192.168.1.110@o2ib, thus causing LNET_PEER_DISCOVERING flag to be set again and peer to be kept in discovery process/loop, but very likely on the ln_dc_working queue instead of ln_dc_request one so out of discovery thread control and should have been probably timed-out later. |

Mount performance is much better with this patch |

Hmm, seems that my patch has also introduced some regression and causes this new LBUG on Client side for different auto-tests sub-tests/steps (like lnet-selftest. lustre-initialization, upon mount, ...) : [ 5914.956548] LNetError: 23347:0:(peer.c:272:lnet_destroy_peer_locked()) ASSERTION( list_empty(&lp->lp_peer_nets) ) failed: [ 5914.960593] LNetError: 23347:0:(peer.c:272:lnet_destroy_peer_locked()) LBUG [ 5914.964063] Pid: 23347, comm: lnet_discovery [ 5914.967234] [ 5914.967234] Call Trace: [ 5914.973027] [<ffffffffc07337ae>] libcfs_call_trace+0x4e/0x60 [libcfs] [ 5914.976440] [<ffffffffc073383c>] lbug_with_loc+0x4c/0xb0 [libcfs] [ 5914.979816] [<ffffffffc06bab42>] lnet_destroy_peer_locked+0x232/0x340 [lnet] [ 5914.983278] [<ffffffffc06bb175>] lnet_peer_discovery_complete+0x295/0x340 [lnet] [ 5914.986724] [<ffffffffc06c0c30>] lnet_peer_discovery+0x6f0/0x11b0 [lnet] [ 5914.990141] [<ffffffff816a904d>] ? __schedule+0x39d/0x8b0 [ 5914.993348] [<ffffffff810b1920>] ? autoremove_wake_function+0x0/0x40 [ 5914.996599] [<ffffffffc06c0540>] ? lnet_peer_discovery+0x0/0x11b0 [lnet] [ 5914.999836] [<ffffffff810b099f>] kthread+0xcf/0xe0 [ 5915.002827] [<ffffffff810b08d0>] ? kthread+0x0/0xe0 [ 5915.005771] [<ffffffff816b4fd8>] ret_from_fork+0x58/0x90 [ 5915.008696] [<ffffffff810b08d0>] ? kthread+0x0/0xe0 Cliff, do you also trigger this ? |

Hi Bruno, Yesterday I tried to make a patch to include both your patch and the one for The test patch which includes both patch also hit the LBUG |

Sarah, Cliff, |

We are doing b2-10 now, will consider this when we move back to master |
| Comment by Cliff White (Inactive) [ 20/Dec/17 ] |
|
We are attempting to test master now, can you rebase your patch on current master? |
| Comment by Bruno Faccini (Inactive) [ 21/Dec/17 ] |
|
Cliff, I have just rebased my change #30147 on latest master. |
| Comment by Cliff White (Inactive) [ 04/Jan/18 ] |
|
We still see client mount hangs on latest master, is this patch in queue for landing? |
| Comment by Peter Jones [ 05/Jan/18 ] |
|
It had not been but I just added it to the chaser list. If there's something you think is important to get landed for soak please flag it either directly or via James so we can expedite it. |
