NAME


xnbd-bgctl - Control a server running xnbd-server(8) through its control socket

SYNOPSIS


xnbd-bgctl --query CONTROL_SOCKET

xnbd-bgctl [--force] --switch CONTROL_SOCKET

xnbd-bgctl [--progress] --cache-all CONTROL_SOCKET

xnbd-bgctl --cache-all2 CONTROL_SOCKET

DESCRIPTION


With the xnbd-bgctl command you can connect to an xnbd-server control channel and instruct
it to act as directed. You may pass an argument to the control program which is then
forwarded, on your behalf, to the server instance.

OPTIONS


The following options are supported:

--cache-all
If the remote xnbd-server acts as proxy server, this command instructs the controlling
xnbd-server instance to cache all blocks on its associated block disk. Upon completion
the controlled xnbd-server instance holds all data from the origin instance and it is
no longer necessary to act as proxy.

--cache-all2
This command is identical to --cache-all but detaches the process from the terminal
and is hence using a dedicated connection for data transfer. Not implemented fully
yet.

--query
This command retrieves completion statistics from the proxy server instance. It
returns the number of cached blocks on the server.

--reconnect
This command recovers from a lost connection by re-establishing connectivity with the
origin server. This command expects two additional arguments, the REMOTE_HOST, and the
REMOTE_PORT you want to connect to, to recover from a disconnected session.

--switch
This command stops the proxy server and restarts in target mode. All client sessions
are preserved.

--exportname NAME
If the server supports to access devices by an identifier, use NAME to request access
to a particular volume. This command is useful in combination with an xnbd-wrapper,
not a plain xnbd-server.

--progress
Enables display of a progress bar on stderr. Disabled by default.

--force
Ignore risks, use with care. Disabled by default.

(--shutdown)
Deprecated alias to --switch, please do not use.

POSITIONAL ARGUMENTS


The following positional options are supported:

CONTROL_SOCKET
The Unix domain socket, the xnbd-server(8) program is listening on.
