Single open but multiple closes
by You Me 06 Aug '18

When I write a lot of data to an NFS share using NFSv3 clients, I see that Nfs-Ganesha opens file once but calls close on same FD multiple times. What is the reason behind that? —You

Change in ffilz/nfs-ganesha[next]: RFC: 9p/tcp: add support for KCM (kernel connection multiplexor)
by GerritHub 05 Aug '18

05 Aug '18

From Dominique Martinet <asmadeus(a)codewreck.org>: Dominique Martinet has uploaded this change for review. ( https://review.gerrithub.io/421314 Change subject: RFC: 9p/tcp: add support for KCM (kernel connection multiplexor) ...................................................................... RFC: 9p/tcp: add support for KCM (kernel connection multiplexor) KCM is a framework that lets the application specify how messages are constructed in a BPF program, so that the kernel can split messages at proper length for us. The main advantage of this is that it saves us one user-space <-> kernel round-trip of read(hdr) then read(rest-of-the-size), as a single recvmsg() will always give us a proper message Ultimately, KCM also has other advantages as we could attach multiple tcp sockets on it and have worker threads read from kcm "clones" that do load-balancing instead of our silly one-thread-per-client system that has been bothering me forever, but just this has advantages. A quick benchmark with ior on a different client with very small messages to stress the packet processing shows: $ mpirun -n 32 ./ior -F -o /mnt/ior_out -t 32 -b 128k -i 10 ... with KCM enabled: write 1.47 1.30 1.35 0.05 2.96137 0 32 32 10 1 0 1 0 0 1 131072 32 4194304 POSIX 0 read 1.43 1.28 1.37 0.04 2.92899 0 32 32 10 1 0 1 0 0 1 131072 32 4194304 POSIX 0 -> taking the best, 4k round-trips in 2.93s = 1.4k req/s with KCM disabled: write 1.32 1.23 1.27 0.03 3.15889 0 32 32 10 1 0 1 0 0 1 131072 32 4194304 POSIX 0 read 1.28 1.17 1.22 0.04 3.27371 0 32 32 10 1 0 1 0 0 1 131072 32 4194304 POSIX 0 -> taking the best, 4k round-trips in 3.15s = 1.3k req/s (There is a lot of noise and my test is too short/only 10 iterations, but that's about 7% difference!) That'd be very interesting to try in ntirpc for NFS A few notes: - KCM is currently broken with small messages that get aggregated by TCP, I have a patch here under construction: https://lkml.kernel.org/m/20180805233921.GA5773@nautica - KCM is disabled by default in most distros anyway... - Even with this patch big messages seem to cause a problem, I need to look into that. - This patch does not check for libbcc properly in cmake Change-Id: Idf040f311d6ca1a30c34bc6e9442073f493b0a52 Signed-off-by: Dominique Martinet <dominique.martinet(a)cea.fr> --- M src/CMakeLists.txt M src/MainNFSD/9p_dispatcher.c M src/MainNFSD/CMakeLists.txt M src/include/config-h.in.cmake 4 files changed, 82 insertions(+), 0 deletions(-) git pull ssh://review.gerrithub.io:29418/ffilz/nfs-ganesha refs/changes/14/421314/1 -- To view, visit https://review.gerrithub.io/421314 To unsubscribe, or for help writing mail filters, visit https://review.gerrithub.io/settings Gerrit-Project: ffilz/nfs-ganesha Gerrit-Branch: next Gerrit-MessageType: newchange Gerrit-Change-Id: Idf040f311d6ca1a30c34bc6e9442073f493b0a52 Gerrit-Change-Number: 421314 Gerrit-PatchSet: 1 Gerrit-Owner: Dominique Martinet <asmadeus(a)codewreck.org>

EIO on NFSv4.1 mounts
by Sriram Patil 03 Aug '18

03 Aug '18

Hi, I was trying to do NFSv4.1 mounts with VFS exports, but I am getting following error on the client side when doing an open, reading TCP record fragment of length 376 reading XID (4 bytes) reading reply for XID 6b8aed78 reading CALL/REPLY flag (4 bytes) read reply XID 6b8aed78 XID 6b8aed78 read 368 bytes xprt = ffff88022e5af000, tcp_copied = 376, tcp_offset = 376, tcp_reclen = 376 27 xid 6b8aed78 complete (376 bytes received) 27 __rpc_wake_up_task (now 4294955572) 27 disabling timer 27 removed from queue ffff88022e5af258 "xprt_pending" __rpc_wake_up_task done xs_tcp_data_recv done 27 __rpc_execute flags=0x4881 27 call_status (status 376) 27 call_decode (status 376) 27 validating UNIX cred ffff8800ba74a780 27 using AUTH_UNIX cred ffff8800ba74a780 to unwrap rpc data decode_opaque_inline: prematurely hit end of receive buffer. Remaining buffer length is 49 words. 27 call_decode result -5 The linux kernel version I am using is 3.13. NFSv4.0 mounts work fine without any problem. I also observed that the NFSv4.1 mounts work well on kernel 4.4. I could not find any info about the minimum required kernel version for using NFSv4.1. This is probably an issue on the NFS client side. Does anyone know the required kernel version for using NFSv4.1? Thanks, Sriram

Re: [Nfs-ganesha-devel] submitting LizardFS FSAL to nfs-ganesha
by Daniel Gryniewicz 03 Aug '18

03 Aug '18

(CCing the new mailing list) Hi, Pawel. This looks like a very good start. There's definitely some issues that will turn up during review, but it should be close to ready for submission. The big remaining issue I can see is the license: The code you linked is GPLv3, but Ganesha is LGPLv3, so the code needs to be relicensed before we can accept it.
