Fixed In Version:		Doc Type:	Bug Fix
Doc Text:	In previous versions of JBoss EAP 6, deployments were only copied to host controllers as needed. Host contollers started with the `--backup` switch did not have all deployments available, so could not be promoted to a domain controller in a failover. In this release all content is copied to the host controller when started with `--backup` allowing for promotion in a failover.	Story Points:	---

Description Tom Fonteyne 2014-05-29 13:42:52 UTC

+++ This bug was initially created as a clone of Bug #1102752 +++

https://issues.jboss.org/browse/WFLY-3418

Above cloned here aiming for 6.2 CP04


    Install node 1
    remove all local servers
    start it in domain mode, so it runs as the DC
    use the CLI to deploy an application

=> the application will end up in the domain/data/content folder as expected.

    Install node 2 on another machine
    remove all local servers
    point it to the DC on node 1
    start in domain mode, so it runs as a HC
    wait a little...
    stop the node 2, and inspect the local domain/data/content
    => empty

    start node 2 again
    on node 1, with the CLI, deploy a second application
    inspect node 2 local domain/data/content
    => the new / 2nd application will have been copied but the original first is still not copied.

Whether you start node 2 with or without "--backup" makes no difference.

Problem:
due to the HC not receiving a full copy of the "content" folder, it is not possible to promote the HC to a DC (when the original DC is down)

Comment 1 Tom Fonteyne 2014-05-29 13:53:37 UTC

workaround:
Do not promote an HC. Instead have a backup of the DC and restore when needed.

Comment 2 Tom Fonteyne 2014-05-29 15:18:12 UTC

workaround2:
use rsync or similar to keep the "content" directory of an HC synced with the DC

Added draft doc text with my understanding of the issue.

Tom or Brian please confirm that it's correct?

doc text sounds good - tx
