WN software/components/symlink/links is undefined #24

almumontiel · 2014-03-17T15:52:31Z

I get this error while compiling a basic grid/wn machine type.

[panc] element at /software/components/symlink/links is undefined

I understand this might be assigned to some variable that is empty at the moment, therefore the list of links is empty.

Could you help me solving this?
Cheers

@almumontiel you may want to reopen this issue against configuration-modules-core repository as it is in fact a flaw in ncm-symlinks that should allow to include the componenent without adding any configuration (doing nothing).

Cheers,

Michel

almumontiel · 2014-03-24T12:17:36Z

thanks.
I just moved it there. Im closing this one then.

jouvin · 2014-03-25T07:39:25Z

My fault! After a more careful look, the problem is in the template library. This happens in particular if you enable NFS on WNs but you don't have WN_SHARED_AREAS correctly defined. Clearly the compilation should work or an explicit error be triggered.

I reopen the issue!

#29 should fix it. Please, could you remove your workaround for the error to reoccur, then update your umd-3 templates (only feature/nfs/client/autofs.pan has been changed) and confirm that the error disappear with the upgraded template.

Note that you may still want to review your local configuration to understand why NFS client is configured without shared areas defined. This may happen if you have NFS_CLIENT_ENABLED explicitly defined in your local configuration. Normally you should let it undefined so that the standard templates do what is appropriate. To check if it is defined, you can use the usual find command to identify the templates that may define this variable:

find cfg/clusters cfg/sites -name \*.pan -exec egrep -l 'variable.*NFS_CLIENT_ENABLED' {} \;

Then either remove -l or look at the templates.

Thank you very much for your quick answer.
I have downloaded the last version of grid/umd-3.
I have removed my workaround.
I have checked that I have WN_SHARED_AREAS defined. Indeed with my workaround, I could see those properly mounted.
I have looked for that variable: NFS_CLIENT_ENABLED, but it is not set, it does not appear.

After this, I compile and i still get the error of the symlink list not defined.
Then I define NFS_CLIENT_ENABLED=undef; but still, I get the same error.

cheers,

Hi,

Please could you touch one profile exhibiting the problem and execute:

external/ant/bin/ant -Dpan.debug.include=feature/nfs/init

Then after touching again the profile

external/ant/bin/ant -Dpan.debug.include=feature/nfs/client/autofs

If possible ensure that only one profile is recompiled to make the output more readable. And post the output.

Michel

lpsc · 2014-03-25T16:27:19Z

Dear Michel,

following the instructions you gave at:
#24.

1.

we just retrieved from github the file feature/nfs/client/autofs.pan into our local installation.

Executing a "ant" gives us the same symlink error.

We also made sure we do not have any NFS_CLIENT_ENABLED defined with the command:

find cfg/clusters cfg/sites -name *.pan -exec egrep -l 'variable.*NFS_CLIENT_ENABLED' {} \;

2.

In a second step, we executed the "and" commands you point out in the issue. Here is the output:

3.

we will now try the workaround proposed by Almudena.
We will tell you what it gives.

Cheers,
Catherine

After trying the work-around Almudena gave us, it compiles fine !
Here is below the template of our WN, we added a single line:

"/software/components/symlink/links"=list();

Thanks !

This is unfortunate that your pan compiler does not seem to work in debug mode (no output). I'll try to follow-up by email.
