Forests with Replicas are not deleted by wipe

[joeglorioso]

I used the configuration suggested in #408 to create forest replicas when bootstrapping MarkLogic. The ml local wipe command does not delete the forests.

<configuration>

      </forests>
    </database>
  </databases>
</configuration>

After ml local bootstrap: Database and Forests

After ml local wipe: Database was deleted but Forests were not

This is on an ml-vagrant generated Linux cluster, using MarkLogic 8.0-6 and the April-2017-dev version of Roxy.

Im curious, are they deleted if you perform a second wipe after the first one? Which version of Roxy and MarkLogic are you using? Thanks for the details, I will try to reproduce this soon.

I tried this, but unfortunately they aren't deleted after a second wipe. I'm using MarkLogic 8.0-6 and the April-2017-dev version of Roxy

I'm not sure where this would be done in the Roxy code, but I believe that forests need to be "disconnected" from their replicas before deleting either. Perhaps that's the issue? For example:

xquery version "1.0-ml"; 

import module namespace admin = "http://marklogic.com/xdmp/admin" at "/MarkLogic/admin.xqy";

let $config := admin:get-configuration()
let $forest := xdmp:forest("forest-1")
let $replica-forest := xdmp:forest("forest-1r")
let $new-config := admin:forest-remove-replica($config, $forest, $replica-forest)
return admin:save-configuration($new-config)

Any luck replicating this? Thanks!

I haven't seen any movement on this - so I'll add it into some of the other work I'm doing for replicas.
