mount.diod  is  the  mount utility for the distributed I/O daemon, which is an I/O forwarding service for
       Linux clusters built upon the Linux 9p file system.

       mount.diod performs two main tasks: 1) connect and authenticate to the diod  server,  and  2)  issue  the
       mount(2) system call with appropriate mount options.

       Authentication  with  the  diod server takes place in user space.  The connected (and authenticated) file
       descriptor is passed as a mount option to the kernel 9p file system

       This command requires root to execute the mount(2) system call.

       The 9p file system must support the 9P2000.L protocol variant, e.g. kernel 2.6.38 or above.

       The  host  portion  of  the  mount  spec  may  optionally  be   supplied   in   hostlist   format,   e.g.
       host1,host2,host3:aname  or  host[1-3]:aname,  in  which case hosts are tried in order until a successful
       connection is obtained.  Post-connect mount errors are immediately fatal.

       If the host portion of the mount spec begins with a forward-slash (/), it refers to the path  to  a  UNIX
       domain socket.

       The following file system specific mount options are handled by mount.diod.

       aname=name
              The aname is the path of the exported file system on the server.  It can be specified in the mount
              spec  in host:aname format like NFS, or it can be specified with this option.  diod will not allow
              an attach to an empty aname.  diod has a built-in  synthetic  control  file  system  that  can  be
              mounted with aname of ctl.  Note that "ctl" must be explicitly exported.

       uname=name
              The user name to authenticate to the diod server.  The default is uname=root.

       access=mode
              Select  the  access  mode.   access=user (default) causes the mount to support multiple users, and
              requires root authentication.  access=<uid> restricts access at the client to only  the  specified
              user.

       port=n Connect to the diod server on the specified port.  The default is the IANA-assigned 9pfs port 564.

       trans=name
              Select a transport.  mount.diod only supports trans=fd because of its strategy for authentication.

       rfdno=n,wfdno=n
              The  file  descriptor for reading and writing with trans=fd.  If set, mount.diod assumes this file
              descriptor is already connected to a diod server and ignores host in the device specification, and
              the port=n option.

       msize=n
              The msize is the max 9P packet payload size.  The default is 65512 (65536-24)

       version=name
              Select 9P protocol version.  diod only supports 9p2000.L.

       cache=mode
              Specify a caching policy.  By default, no caches are used.  If cache=loose, no attempts  are  made
              at consistency.  This mode is intended for exclusive, read-only mounts.  If cache=fscache, use FS-
              Cache for a persistent, read-only cache backend.

       cachetag
              In  the  context  of  cache=fscache, select the cache tag to use for this session.  Cache tags for
              existing cache sessions are listed in /sys/fs/9p/caches.

       nodevmap
              Do not map  special  files.   Represent  them  as  normal  files.   This  can  be  used  to  share
              devices/named pipes/sockets between hosts.

       debug=n
              Specifies debug level for the kernel 9p module.  The debug level is a bitmask.
              0x01  = display verbose error messages
              0x02  = developer debug (DEBUG_CURRENT)
              0x04  = display 9p trace
              0x08  = display VFS trace
              0x10  = display Marshalling debug
              0x20  = display RPC debug
              0x40  = display transport debug
              0x80  = display allocation debug
              0x100 = display protocol message debug
              0x200 = display Fid debug
              0x400 = display packet debug
              0x800 = display fscache tracing debug
              The  debug  level  is  global, i.e. it applies to all 9P file systems and it remains set after the
              file system is unmounted.  The default is debug=0.
