    Hot-deploy failure with farming in cluster

    Wolf-Christian Herold Newbie

      I'm usong JBoss 3.2.3 on Linux 2.4.x JDK 1.4.2.

      I'm using two nodes in a cluster using autoDiscovery with multicast.
      For deployment I use farming, by copying the files to the farming directoryon node1.

      In some cases it's running without problems (especialy if I'm testing it for get more information about the errorr).

      But in many cases the file are deployed on node1 but are only deleted on node2. In most cases a touch on the files in farm/ on node1 redeploy the files and the second time they will be deployed also on node2.

      It looks like all files are deleted but not copied to the second node.

      Next it looks to me all files are deleted and then deployed.
      Is it true, that all files will be deleted together and than deployed again.
      It looks like an UNDEPLY and the a new DEPLOY.
      I thought there should be a hotdeploy which do not undeploy all files first .
      Just to be shure my running application is always online and reachable from client. If I undeploy the files, there might be a short time where the application is unavailable. On the local node I could see that all request will be served and each file will be redeployed each after the other.
      Running request are finished first before redploying the jars.

      Is this the same procedure on clustered nodes using farming?

      Thanks in advance

      This is my cluster.log when deploying succeed:

      In some cases only the first part is done
      doUndeployment(),
      farmUndeployment() .....

      and no files are deployed and all files in farm/ on nodes2 are deleted.
