System is running CentOS 7.3, serving files over both ethernet and infiniband, but the vast majority of traffic is over infiniband
I just stood up a new file server that is now generating large numbers of the following error:
[2007827.701033] rpc-srv/tcp: nfsd: sent only 618872 when sending 1048708 bytes - shutting down socket [2007835.313884] rpc-srv/tcp: nfsd: sent only 75908 when sending 1048708 bytes - shutting down socket
I increased the tcp_rmem and wmem to a max of 32mb, but the problem persists
net.ipv4.tcp_rmem = 4096 87380 33554432 net.ipv4.tcp_wmem = 4096 65536 33554432
Are there any other ways I could tune this to get around the issue?
