The mini design of syncfiles for cumulus

1. The generation of cumulus osimage: copycds /iso/cumulus-3.5.2-armel/cumulus-linux-3.5.2-bcm-armel.bin determine the file ./cumulus-linux-3.5.2-bcm-armel.bin, if the output is data, it will perform the following 3 steps:

   a. run “cumulus-linux-3.5.2-bcm-armel.bin” and get the binary information and generate the osimage name

    # ./cumulus-linux-3.5.2-bcm-armel.bin
    Verifying image checksum ...OK.
    Preparing image archive ... OK.

    =====================
    Description: Cumulus Linux 3.5.2
    Release: 3.5.2
    Architecture: armel
    Switch-Architecture: bcm-armel
    Build-Id: bab9bc5z1d1b1f3

    Min-Ram-Size: 536870912
    mkimage-version: cl3u13
   

   b. copy the binary to the /install/cumulus3.5.2/cumulus-3.5.2-armel/

   c. create the the following osimage definition

   [root@c910f03c05k21 cumulus_mlx]# lsdef -t osimage -o cumulus3.5.2-armel
   Object name: cumulus3.5.2-armel
       imagetype=linux
       osarch=armel
       osvers=cumulus3.5.2
       pkgdir=/install/cumulus3.5.2/armel/cumulus-linux-3.5.2-bcm-armel.bin  #<<< might be a comma separated list, the 1st should be the full path to the bin file
       synclists=/tmp/compute.synclist #<<<<<<<synclist specified here>>>>>>>>>>>>
       postscripts=xxxx
       postbootscripts=xxxx
   

2. nodeset mid05tor12 osimage=cumulus3.5.2-armel

   [root@briggs01 ~]# lsdef mid05tor12
   Object name: mid05tor12
       groups=switch,edge_switch
       ip=172.11.205.12
       mac=xx:xx:xx:xx:xx:xx
       mgt=switch
       netboot=onie
   

   nodeset performs the following operations:

   (1) find the "*.bin" file under the first entry in osimage.pkgdir, then copy the "*.bin" to /install/osimages/cumulus3.5.2-armel

   (2)assign the node.provmethod to the osimage name

   (3)run "makedhcp -a ", generate the dhcp lease with full path to the bin file in default-url option

3. add an option -r [the full path to scp or rsync] for updatenode to select scp/rsync, refine the code logic in updatenode and xdcp to enable this

   # updatenode mid05tor12 -F -r /usr/bin/scp
   # xdcp mid05tor12 -F -r /usr/bin/scp
   

4. refine the code logic in startsyncfiles.awk , add an option -r to select the scp or rsync, the compute node can select the scp/rsync according to the existence of the 2 executables

   # syncfiles -r usr/bin/scp
