1 What:		/sys/class/rnbd-client
5 Description:	Provide information about RNBD-client.
6 		All sysfs files that are not read-only provide the usage information on read:
10 		    # cat /sys/class/rnbd-client/ctl/map_device
16 		    > addr ::= [ ip:<ipv4> | ip:<ipv6> | gid:<gid> ]
18 What:		/sys/class/rnbd-client/ctl/map_device
34 		    I.e. "clt_hostname-srv_hostname" could be a natural choice.
41 			ip:<IPv6>
42 			ip:<IPv4>
47 		    path=ip:10.0.0.66
50 		The connection will be established to this server from any client IP address.
54 		    path=ip:10.0.0.66,ip:10.0.1.66
63 		    Path to the block device on the server side. Path is specified
68 		    <dev_search_path>/<device_path> block device.  On success,
69 		    a /dev/rnbd<N> device file, a /sys/block/rnbd<N>/
70 		    directory and an entry in /sys/class/rnbd-client/ctl/devices
75 		the following parameter "dev_search_path=/run/rnbd-devs/%SESSNAME%",
77 		will try to open: /run/rnbd-devs/blya/sda.
81 		    mapped as "ro" read-only or "rw" read-write. The server allows
83 		    access mode has to be specified if a second mapping in read-write
89 		  specifies the number of poll-mode queues. If the IO has HIPRI flag,
90 		  the block-layer will send the IO via the poll-mode queue.
91 		  For fast network and device the polling is faster than interrupt-base
96 		  Set -1 if you want to set it as the number of CPUs
97 		  By default rnbd client creates only irq-mode queues.
99 		  NOTICE: MUST make a unique session for a device using the poll-mode queues.
108 		---------------------------------
111 		o  The symlink /sys/class/rnbd-client/ctl/devices/<device_id>@<session_name>
112 		points to /sys/block/<dev-name>. The last part of the symlink destination
114 		path the path to the device /dev/<dev-name> can be build.
116 		* /dev/block/$(cat /sys/class/rnbd-client/ctl/devices/<device_id>@<session_name>/dev)
121 What:		/sys/class/rnbd-client/ctl/devices/
126 		/sys/class/rnbd-client/ctl/devices/<device_id>@<session_name>, which points
127 		to the block device created by rnbd (/sys/block/rnbd<N>/).
