Re: copy w/failover clarification

[christian pearce]

Jason,

The following is an example of the failover in action.  Yes you can
have multiple failovers.

I would like to see the ability to define mutiple servers.  Alas I
think will have to wait for Cfengine 3.

pearcec@wideload:/var/tmp$ cat copy-test.cf
control:

    actionsequence = ( copy )

    AddInstallable = ( failed1 failed2 broken )

copy:

    any::
        /var/tmp/test
            dest=/var/tmp/test
            server=192.168.1.2
            failover=failed1

    failed1::
        /var/tmp/test
            dest=/var/tmp/test
            server=192.168.1.3
            failover=failed2

    failed2::
        /var/tmp/test
            dest=/var/tmp/test
            server=192.168.1.4
            failover=broken

alerts:

    broken::
        "Failed to copy configs"
pearcec@wideload:/var/tmp$ cfagent -f ./copy-test.cf  -I
cfengine:: Couldn't open a socket
cfengine:: Unable to establish connection with 192.168.1.2 (failover)
