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 sys-
log, 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 bidirection-
ally, 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 set-
ting 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 supplemen-
tary 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

0x01 - log decoded 9P protocol messages
-c, --config-file PATH
