warewulf 유틸리티

warewulf 답게 ww로 프로그램 이름이 시작한다.

# ww wwbootstrap  wwinit       wwmkchroot   wwsh         wwvnfs wwconfig     wwlivesync   wwnodescan   wwuseradd

 

초기화 명령으로 database랑 ssh_keys는 했는데 의외로 초기화 하는 항목이 많다?

wwsh node를 통해서도 추가가 가능하다.

# wwnodescan
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.
