USAGE: /usr/bin/wwnodescan [options] nodes....
SUMMARY:
Scan for new systems making DHCP requests.
GENERAL OPTIONS:
-h, --help Show the help/utilization summary
-d, --debug Display debugging information
-v, --verbose Be more verbose in output
-f, --file <file> Create Warewulf script instead of auto-import
-l, --listen <iface> Interface to listen on (tcpdump -D for list)
-c, --tcpdump <cmd> Specify the full path to the tcpdump command
-T, --tshark <cmd> Specify the full path to the tshark command (Only IB Mode)
-x, --max [<cnt>] Exit after <cnt> new nodes (0 for auto)
MODES:
-t, --test Test mode; do not modify data store
-r, --replace Replace existing nodes (by name)
-a, --autoconfig Assign HW addresses to unassigned nodes
-I, --infiniband Use tshark to look for Client Identifier, compatible with Mellanox FlexBoot.
SETTINGS:
-n, --netdev <dev> Network device for the new node(s)
-i, --ipaddr <addr> IP address for the new node(s)
-m, --netmask <mask> Netmask for the new node(s)
-V, --vnfs <vnfs> VNFS for the node(s)
-b, --bootstrap <name> Bootstrap for the node(s)
-g, --groups <groups> Groups for the node(s)
NODES:
You can scan for any number of nodes; this program will exit after all
specified nodes have been found. The IP address provided will be
incremented for each node found, and nodes will be added in the order
given on the command line.
DEFAULTS:
As with all object types, you can create a template node object called
DEFAULT whose attributes will be used as the default values for all
new nodes. You can override some of these defaults using the options
shown above.
EXAMPLES:
# wwnodescan --ipaddr 10.0.1.10 --netmask 255.255.0.0 --vnfs=sl6.vnfs
--bootstrap=`uname -r` n0000 n0001
# wwsh node new DEFAULT --groups=grp1,test
# wwsh provision node DEFAULT --vnfs=sl6.vnfs --bootstrap=`uname -r`
# wwnodescan --ipaddr 10.0.1.100 --netmask 255.255.0.0 n00[02-19]

wwmkvnfs 로 만든 디렉토리를 VNFS 이미지로 생성하는 유틸리티
# wwvnfs
_FORTIFY_SOURCE requires compiling with optimization (-O) at /usr/lib64/perl5/features.ph line 207.
USAGE: /usr/bin/wwvnfs [options] (name)
OPTIONS:
-c, --chroot Path to the chroot to use for this VNFS image
-r, --root Alias for --chroot
-h, --help Usage and help summary
-o, --output Output the binary VNFS to a file instead of importing it
directly into Warewulf
-e, --exclude Exclude a file or directory from the VNFS image
--excludefile Path to a file that contains a list of files and directories to
exclude from the VNFS image
--hybridize Hybridize a list of files or directories from the VNFS image
(requires --hybridpath to be set, or files are just excluded)
--hybridizefile Path to a file that contains a list of files and directories to
be hybridized from the VNFS image
--hybridpath Path to use within the VNFS where the links will be pointed to in
the final image (this needs to be added to the VNFS fstab!)
NOTES:
When wwvnfs is run for the first time on a VNFS, it will attempt to create a
configuration file in the default warewulf config dir (/etc/warewulf/vnfs/) or in
the users ~/.warewulf/vnfs directory. Once the configuration file has been written
and updated, you can simply run 'wwvnfs [vnfs_name]' to rebuild the image. You can
temporarily override any of these options via command line arguments.
EXAMPLES:
# wwvnfs --chroot=/var/chroots/rhel-6
# wwvnfs custom_name --chroot=/var/chroots/rhel-6 --hybridpath=/hybrid/vnfs_name
# wwvnfs --chroot=/var/chroots/rhel-6 --output=rhel-6.vnfs
# wwvnfs custom_name

# wwlivesync
USAGE: /usr/bin/wwlivesync (options) [targets]
SUMMARY:
The live sync command will spawn rsync commands to update the running node
operating system (VNFS) live. This command should only be used for minor VNFS
updates, as large updates including library load could potentially break binary
compatibility.
OPTIONS:
-l, --lookup Identify nodes by specified property (default: "name")
-f, --files Pass a list of files to sync instead of the entire VNFS
--show Just print what it would do instead of actually do it
--logdir Directory of per-node logs (/var/log/wwlivesync)
--verbose Increase verbosity level
--quiet Decrease verbosity level
--debug Print debugging messages
-h, --help Display this usage summary
TARGETS:
The target(s) specify which node(s) will be affected by the chosen
action(s). By default, node(s) will be identified by their name(s).
Use the --lookup option to specify another property (e.g., "hwaddr"
or "groups").
All targets can be bracket expanded as follows:
n00[0-99] All nodes from n0000 through n0099 (inclusive)
n00[00,10-99] n0000 and all nodes from n0010 through n0099
EXAMPLES:
# wwlivesync n00[00-19] |
# wwuseradd

-G, --groups GROUPS list of supplementary groups of the new
account

(non-unique) UID
-p, --password PASSWORD encrypted password of the new account
-r, --system create a system account
-R, --root CHROOT_DIR directory to chroot into
