[PATCH v5 0/9] Add a tool for using the new sysfs files

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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:
	rpcctl client
 	rpcctl switch
 	rpcctl switch set
 	rpcctl xprt
 	rpcctl xprt set

So you can print out information about every switch with:
	anna@client ~ % rpcctl switch
	switch 0: xprts 1, active 1, queue 0
		xprt 0: local, /var/run/gssproxy.sock [main]
	switch 1: xprts 1, active 1, queue 0
		xprt 1: local, /var/run/rpcbind.sock [main]
	switch 2: xprts 1, active 1, queue 0
		xprt 2: tcp, 192.168.111.1 [main]
	switch 3: xprts 4, active 4, queue 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 ~ % rpcctl xprt
	xprt 0: local, /var/run/gssproxy.sock, port 0, state <CONNECTED,BOUND>, main
		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 <CONNECTED,BOUND>, main
		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 <CONNECTED,BOUND>, main
		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 <CONNECTED,BOUND>, main
		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 rpcctl 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 rpcctl 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 % rpcctl switch --id 3
	switch 3: xprts 4, active 4, queue 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 rpcctl switch set --id 4 --dstaddr server2.nowheycreamery.vm
	switch 3: xprts 4, active 4, queue 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

Changes in v5:
- Rename from 'rpcctl' to 'rpcctl'
- Rename subcommands 'xprt-switch" to 'switch' and 'rpc-client' to 'client'
- Clean up how the displayed strings are generated
- Handle kernels that don't yet have the srcaddr patch

Thoughts?
Anna
