<div class="jive-rendered-content"><p>David Lloyd argued against the .failed files essentially because of the problem you raise. The true representation of the state of the server is in the standalone.xml file, not in these marker files.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The FS scanner is a client to the core server in pretty much the same way that a user using the CLI is and the someone using web console will be. It detects changes on the filesystem, makes requests to the core server management layer and the writes up .failed, .deployed etc based on what it response it gets. Those files represent the client view of the system though; if the server doesn't respond, the FS scanner eventually gives up and marks a failure. But because the server didn't respond the FS scanner doesn't really know the true state on the server side.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The server isn't responding probably due to JBAS-9010, which is being worked. The "Failed to execute deployment operation in allowed timeout [60]" message needs to be beefed up to make it clear that this is an anomalous situation, the scanner doesn't know what happened, and the user needs to investigate and clean up.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><a class="jive-link-external-small" href="https://issues.jboss.org/browse/JBAS-9020">https://issues.jboss.org/browse/JBAS-9020</a> will help with the cleanup issue. Currently we don't track where deployment content comes from, and we treat all content the same, whether it was scanned in from deployments/ or installed into the system via CLI or web console. As a result, following reboot we lose track of whether stuff that was installed by the scanner is no longer present and needs to be undeployed.</p></div>
