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:

(1) 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.

(2) copy the binary to the /install/osimages/cumulus-3.5.2-armel/

(3) create the the following osimage definition, the provmethod attribute should be the full path to the installation binary for backward compatibility

[root@c910f03c05k21 cumulus_mlx]# lsdef -t osimage -o cumulus3.5.2-armel
Object name: cumulus3.5.2-armel
    imagetype=onie
    osarch=armel
    osvers=Cumulus Linux 3.5.2
    pkgdir=/install/osimages/cumulus-3.5.2-armel/
    provmethod=/install/osimages/cumulus-3.5.2-armel/cumulus-linux-3.5.2-bcm-armel.bin #<<<<<full path to binary to keep backward compatibility
    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

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

#xcat command: syncfiles -r   /usr/bin/scp
