NAME

       diod - distributed I/O daemon

SYNOPSIS

       diod [OPTIONS]

DESCRIPTION

       diod  is  the  distributed  I/O  daemon  server,  which implements I/O forwarding on Linux
       clusters.

       Configuration is read from the diod.conf (5)  config  file.   Some  configuration  can  be
       overridden on the command line, as described below.

OPTIONS

       -f, --foreground
              Do  not change working directory to /var/run, drop the controlling terminal, or run
              in the background.  Send logs to stderr not syslog, unless sent somewhere  else  by
              -L.

       -r, --rfdno INT

       -w, --wfdno INT
              Serve   a  connected  client  inherited  on  the  specified  read  and  write  file
              descriptors.  For file descriptors connected bidirectionally, the two  options  may
              be set to the same value.

       -l, --listen address
              Set  the  listen address.  The address may be in the form of HOST:PORT, IP:PORT, or
              /path/to/unix_domain_socket  form  (default  0.0.0.0:564).   This  option  may   be
              specified more than once.  It overrides the listen config file setting.

       -t, --nwthreads INT
              Set  the  number of worker threads to spawn to handle 9P operations for each unique
              aname.  This option overrides the nwthreads setting in diod.conf (5).  The  default
              is 16.

       -e, --export PATH
              Set  the  file system to be exported.  This option may be specified more than once.
              It overrides the exports setting in diod.conf (5).

       -E, --export-all
              Export everything in the server's /proc/mounts.

       -o, --export-opts OPT[,OPT,...]
              Set global export  options.   This  option  overrides  the  exportopts  setting  in
              diod.conf (5).

       -n, --no-auth
              This option allows users to attach without security credentials.  It overrides  the
              auth_required setting in diod.conf (5).

       -N, --no-userdb
              This option disables password/group lookups.  It  allows  any  uid  to  attach  and
              assumes  gid=uid,  and  supplementary  groups  contain  only  the  primary gid.  It
              overrides  the userdb setting in diod.conf (5).

       -S, --allsquash
              Remap all users to the squash user.  The attaching user need not be present in  the
              server's  password  file.  This option overrides the allsquash setting in diod.conf
              (5).

       -U, --squashuser
              Set the squash user.  The default is nobody.  This option overrides the  squashuser
              setting  in  diod.conf  (5).   Note:  if diod is not run as root, the effective uid
              overrides the squashuser.

       -u, --runas-uid UID
              Run the server as UID and only allow that user to attach.  If invoked as root, diod
              sets  real  and  effective uid, gid, and supplementary groups to those belonging to
              UID.

       -L, --logdest DEST
              Set the destination for logging.  Possible destinations are  syslog:facility:level,
              stderr,  stdout,  or  a  file  name.   This option overrides the logdest setting in
              diod.conf (5).

       -d, --debug MASK
              Set the debug mask.  The bit values are:
              0x01 - log decoded 9P protocol messages

       -c, --config-file PATH
              Set config file path.
