Copying files into cache/schema on an nfs mount makes the files available in the container but upon restart of ODL a new container is created that does not see the yang files.</p> <p> </p> <p>Need a mechanism to recreate the cache index so that the side loaded models can be preserved across container re-creates</p> NETCONF-605

Support cache refresh without restart of ODL

Upon ODL restart does it start a new docker container. In that case pointing the new container towards the proper nfs mount should solve the issue.</p> <p>From what i know, ODL restart which is within a docker container does not bring up a new filesystem, because the namespace is not deleted unless the docker container is deleted/removed.</p> <p>Or are you referring to any other container here?</p> <p>Please let us know your view.</p> <p>BR</p> <p>Manoj</p> <p>Hi Brian,</p> <p>A gentle reminder.</p> <p>BR</p> <p>Manoj</p> <p>I tried to work around this problem by making the cache/schema directory part of an NFS mount but restarting ODL seemed to ignore the files in the directory. Perhaps the helm chart wasnt right but it seemed that ODL created the directory on boot rather than seeing one already there.</p> <p>I'll see if I can re-create the problem</p> <p>These directories should remain by a simple karaf stop/start, so maybe something extra is happening in your setup?</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java">$ ls -altr cache total 0 drwxr-xr-x@ 21 jamoluhrsen staff 672 May 20 15:21 .. drwxr-xr-x 2 jamoluhrsen staff 64 May 20 15:21 schema drwxr-xr-x 4 jamoluhrsen staff 128 May 20 15:22 . drwxr-xr-x 176 jamoluhrsen staff 5632 May 20 15:35 34.222.248.49 $ ./bin/karaf Apache Karaf starting up.
