From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx> When a data server goes down, it can currently take 3 minutes for the RPC connection attempt to give up, and return control to the NFS layer. If the file is mirrored, we usually want to fail the attempt to the downed data server much earlier, and retry using one of the other mirrors. This patchset sets the connect timeout to be closer to the I/O timeout value for the case of pNFS to NFSv3 data servers. v2: - Don't override connect timeouts in rpc_clnt_add_xprt - Don't override specified connect timeouts at setup Trond Myklebust (5): SUNRPC: Set the TCP_SYNCNT to match the socket timeout SUNRPC: Refactor and simplify connect timeout SUNRPC: Allow specification of TCP client connect timeout at setup SUNRPC: Don't override connect timeouts in rpc_clnt_add_xprt() NFS/pNFS: Set the connect timeout for the pNFS flexfiles driver fs/nfs/client.c | 2 ++ fs/nfs/internal.h | 2 ++ fs/nfs/nfs3client.c | 3 ++ fs/nfs/pnfs_nfs.c | 3 ++ include/linux/sunrpc/clnt.h | 2 ++ include/linux/sunrpc/xprt.h | 2 ++ net/sunrpc/clnt.c | 7 +++++ net/sunrpc/xprtsock.c | 55 +++++++++++++++++++++++++++---------- 8 files changed, 61 insertions(+), 15 deletions(-) -- 2.41.0
