Sids and JP2s over NFS mount?

Postby peterm » Thu Feb 05, 2009 8:22 am

Greetings-

I have a couple of issues with a new RHEL5 ES6.1 deployment.

I have the sids/jp2s on an NFS cluster, whereas the imagery is organized based on UUID, which is also the filename.
I can navigate the directory structure within the LT browser, but it will not actually display the imagery. Is there something I'm missing?

<Catalog name="NYPL">
<Provider name="file" root="archive" volume="/efs"/>
<Property name="Description">
NYPL Mr. SID Repository
</Property>
</Catalog>

efs is the autofs root, archive is the mount which contains the directory structure.

Thanks.

The daemon user needs read access to the imagery. Did you give the daemon user read access?

Yep

The NFS is read open for all production hosts.

If I explicitly direct the browser to the viewer with said image, it shows no image, and no error.

I replied to your email, a couple of times, but felt maybe the issue should be documented here.

Thanks for the help.

Good and Bad news.

Well, looks like the file extension is required in order for this to work. This does not work in our environment.

Is there a URL var that I can use to specify what type of file it is?

We have a presentation system that serves these up so I can figure out what type of file it is in that.

Do I understand correctly that you do not have the .sid or .jp2 extension on your files?

If so, the extension is required. As far as I know there is no workaround for that.
