Re: copy failover

[Jeffrey Koetsier]

I gathered some more info. Hopefully it gives you some more insight.

-CONFIG- (this file gets included from my cfagent.cf)

control:
       addinstallable  = ( myfile myretry )
       actionsequence  = ( copy )
       fileserver      = ( cfengine.domain.nl )

copy:
 any::
       /cfengine/files/FILEA   dest=/etc/FILENAME mode=755
                               owner=root group=root
                               server=$(fileserver)
                               failover=myretry define=myretry 
elsedefine=myretry

 myretry::
       /cfengine/files/FILEB   dest=/etc/FILENAME mode=755
                               owner=root group=root
                               server=$(fileserver)

I gave the FILEA all the possible define entries to just execute 
'myretry' no matter what.
But it won't do it.

-CFAGENT debug info-
/cfengine/files/FILEA
+755
-7022
dest: /etc/FILENAME
action: fix
Size > -1
recurse=0
uids = ( 0 )
gids = ( 0 )
filters:
exclude:
ignore:
symlink:
include:
classes = any
method = t (time/checksum)
server = cfengine.domain.nl (encrypt=n,verified=n)
accept the server's public key on trust? n
purging = n
host entry cache = 1473192 = 10.200.197.112
Define myretry
ElseDefine myretry
FailoverClasses myretry

/cfengine/files/FILEB
+755
-7022
dest: /etc/FILENAME
action: fix
Size > -1
recurse=0
uids = ( 0 )
gids = ( 0 )
filters:
exclude:
ignore:
symlink:
include:
classes = myretry
method = t (time/checksum)
server = cfengine.domain.nl (encrypt=n,verified=n)
accept the server's public key on trust? n
purging = n
host entry cache = 1473384 = 10.200.197.112
Define
ElseDefine
FailoverClasses myretry

-CFSERVD debug-
box: Strongly authentication of client client.domain.nl/10.200.197.113
box: Couldn't stat filename /cfengine/files/FILEA from host client.domain.nl

box: lstatbox: Host authorization/authentication failed or access denied
box: From (host=client.domain.nl,user=root,ip=10.200.197.113)

Somehow if the file is 'unstattable' (not there) it returns an access 
denied and doesn't set any variables.
When I put FILEA on my fileserver, it will copy it, and also (because I 
used define/elsedefine/failover all together) copy FILEB.
And in the debug output I see nicely: AddMultipleClasses(myretry), 
AddClassToHeap(myretry), Appending [myretry] and then copies FILEB.

Thanks for the support
