From: Anna Schumaker <Anna.Schumaker@xxxxxxxxxx> These patches implement a tool that can be used to read and write the sysfs files, with subcommands! They need Olga's most recent patches to run. The following subcommands are implemented: nfs-sysfs.py rpc-client nfs-sysfs.py xprt nfs-sysfs.py xprt set nfs-sysfs.py xprt-switch nfs-sysfs.py xprt-switch set So you can print out information about every xprt-switch with: anna@client % ./nfs-sysfs.py xprt-switch switch 0: num_xprts 1, num_active 1, queue_len 0 xprt 0: local, /var/run/gssproxy.sock switch 1: num_xprts 1, num_active 1, queue_len 0 xprt 1: local, /var/run/rpcbind.sock switch 2: num_xprts 4, num_active 4, queue_len 0 xprt 2: tcp, 192.168.111.188 xprt 3: tcp, 192.168.111.188 xprt 5: tcp, 192.168.111.188 xprt 6: tcp, 192.168.111.188 switch 3: num_xprts 1, num_active 1, queue_len 0 xprt 7: tcp, 192.168.111.1 switch 4: num_xprts 1, num_active 1, queue_len 0 xprt 4: tcp, 192.168.111.188 And information about each xprt: anna@client % ./nfs-sysfs.py xprt xprt 0: local, /var/run/gssproxy.sock, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 1: local, /var/run/rpcbind.sock, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 2: tcp, 192.168.111.188, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 3: tcp, 192.168.111.188, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 4: tcp, 192.168.111.188, state <BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 5: tcp, 192.168.111.188, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 6: tcp, 192.168.111.188, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 xprt 7: tcp, 192.168.111.1, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 You can use the `set` subcommand to change the dstaddr of individual xprts: anna@client % ./nfs-sysfs.py xprt --id 2 xprt 2: tcp, 192.168.111.188, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 anna@client % sudo ./nfs-sysfs.py xprt set --id 2 --dstaddr server2.nowheycreamery.vm xprt 2: tcp, 192.168.111.186, state <CONNECTED,BOUND>, num_reqs 2 cur_cong 0, cong_win 256, min_num_slots 2, max_num_slots 65536 binding_q_len 0, sending_q_len 0, pending_q_len 0, backlog_q_len 0 Or for changing the dstaddr of all xprts attached to a switch: anna@client % ./nfs-sysfs.py xprt-switch --id 2 switch 2: num_xprts 4, num_active 4, queue_len 0 xprt 2: tcp, 192.168.111.188 xprt 3: tcp, 192.168.111.188 xprt 5: tcp, 192.168.111.188 xprt 6: tcp, 192.168.111.188 anna@client % sudo ./nfs-sysfs.py xprt-switch set --id 2 --dstaddr server2.nowheycreamery.vm switch 2: num_xprts 4, num_active 4, queue_len 0 xprt 2: tcp, 192.168.111.186 xprt 3: tcp, 192.168.111.186 xprt 5: tcp, 192.168.111.186 xprt 6: tcp, 192.168.111.186 I'm sure this needs lots of polish before it's ready for inclusion, along with needing a Makefile so it can be installed (I've just been running it out of the nfs-utils/tools/nfs-sysfs/ directory). But it's still a start, and I wanted to post it before going on New Baby Leave Part 2 (June 12 - July 11). What does everybody think?
