perfSONAR User Q&A and Other Discussion

[Jon K Hellan <>]

I am still getting

"Cannot retrieve data from rrdjtool library: RRDFETCH failed: opening 
'.rrd': No such file or directory"

with the official release of RRD-MA in perfsonar-bundle-2.0. This is a 
fresh install.

The good news is that I now see the problem in the test suite with the 
included example rrd-database.xml config file. the response 
(/perfsonar/schema/example-instances/perfSONAR/response-4.xml) is:

<?xml version="1.0" encoding="UTF-8"?>
<nmwg:message id="msg4_resp" messageIdRef="msg4"
    type="SetupDataResponse" xmlns:nmwg="http://ggf.org/ns/nmwg/base/2.0/";>
    <nmwg:metadata id="resultCodeMetadata">
        <nmwg:eventType>error.rrdma.rrdjtool</nmwg:eventType>
    </nmwg:metadata>
    <nmwg:data id="resultDescriptionData_for_resultCodeMetadata" 
metadataIdRef="resultCodeMetadata">
        <nmwgr:datum 
xmlns:nmwgr="http://ggf.org/ns/nmwg/result/2.0/";>RRDStorageManager.rrdFetch: 
Cannot retrieve data from rrdjtool library: RRDFETCH failed: opening 
'.rrd': No such file or directory</nmwgr:datum>
    </nmwg:data>
</nmwg:message>

This might make the problem more tractable.

The platform is Debian etch. Java is

java version "1.5.0_07"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
Java HotSpot(TM) Client VM (build 1.5.0_07-b03, mixed mode, sharing)

We'll get a chance to discuss this face to face.
