From: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> These patches implement a tool that can be used to read and write the sysfs files, with subcommands! The following subcommands are implemented: rpcsys rpc-client rpcsys xprt rpcsys xprt set rpcsys xprt-switch rpcsys xprt-switch set So you can print out information about every xprt-switch with: anna@client ~ % rpcsys xprt-switch switch 0: num_xprts 1, num_active 1, queue_len 0 xprt 0: local, /var/run/gssproxy.sock [main] switch 1: num_xprts 1, num_active 1, queue_len 0 xprt 1: local, /var/run/rpcbind.sock [main] switch 2: num_xprts 1, num_active 1, queue_len 0 xprt 2: tcp, 192.168.111.1 [main] switch 3: num_xprts 4, num_active 4, queue_len 0 xprt 3: tcp, 192.168.111.188 [main] xprt 4: tcp, 192.168.111.188 xprt 5: tcp, 192.168.111.188 xprt 6: tcp, 192.168.111.188 And information about each xprt: anna@client ~ % rpcsys xprt xprt 0: local, /var/run/gssproxy.sock, port 0, state <MAIN,CONNECTED,BOUND> Source: (einval), port 0, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 1: local, /var/run/rpcbind.sock, port 0, state <MAIN,CONNECTED,BOUND> Source: (einval), port 0, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 2: tcp, 192.168.111.1, port 2049, state <MAIN,CONNECTED,BOUND> Source: 192.168.111.222, port 959, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 3: tcp, 192.168.111.188, port 2049, state <MAIN,CONNECTED,BOUND> Source: 192.168.111.222, port 921, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 5: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 671, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 xprt 6: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 934, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 You can use the `set` subcommand to change the dstaddr of individual xprts: anna@client ~ % sudo rpcsys xprt --id 4 xprt 4: tcp, 192.168.111.188, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 anna@client ~ % sudo rpcsys xprt set --id 4 --dstaddr server2.nowheycreamery.com xprt 4: tcp, 192.168.111.186, port 2049, state <CONNECTED,BOUND> Source: 192.168.111.222, port 726, Requests: 2 Congestion: cur 0, win 256, Slots: min 2, max 65536 Queues: binding 0, sending 0, pending 0, backlog 0, tasks 0 Or for changing the dstaddr of all xprts attached to a switch: anna@client % rpcsys xprt-switch --id 3 switch 3: num_xprts 4, num_active 4, queue_len 0 xprt 3: tcp, 192.168.111.188 [main] xprt 4: tcp, 192.168.111.188 xprt 5: tcp, 192.168.111.188 xprt 6: tcp, 192.168.111.188 anna@client % sudo rpcsys xprt-switch set --id 4 --dstaddr server2.nowheycreamery.vm switch 3: num_xprts 4, num_active 4, queue_len 0 xprt 2: tcp, 192.168.111.186 [main] xprt 3: tcp, 192.168.111.186 xprt 5: tcp, 192.168.111.186 xprt 6: tcp, 192.168.111.186 I renamed the tool to "rpcsys" after the discussion at the bakeathon. I think this is at least a better name, but if anybody has other ideas please let me know! Thoughts?
