Re: [help] Trying to use stitching in a slice

[Niky Riga]

Hi Andy,

I am forwarding your email to geni-users since the right set of people
are there to help you debug this. I have never seen this error before,
maybe Tom or Xi can shed some light.

Good luck,
Niky

This is not an RSpec problem, I was able to create a sliver with the
RSpec in the email.
Also, this is not a gcf-2.4 problem, I was able to verify the RSpec with
gcf-2.4.

This is a slice operation problem at the ION aggregate.

From the email... The slice name is "Infrastructure" while the project
is "InstaGENI-PlanetLab".
I wonder if we are running into some issue with the number of characters
in this slice URN
"urn:publicid:IDN+ch.geni.net:InstaGENI-PlanetLab+slice+Infrastructure"
? Or the handling
of this slice for a new stitching user?

The project and slice names obey our usual rules to avoid issues. But I believe Luisa is correct:

http://trac.gpolab.bbn.com/gcf/wiki/OmniTroubleShoot#Q.ItrytocreateasliverwithaPLAMandIgetaFault102error

Given your long project name, try with a slice named "ab" or something else super short and see if that works.

As you recall, the ION AM relies on SFA/MyPLC. It appears that that's where the problem is arising.

I tried it with shorter project and slice names and it worked. Looks
like some kind of a bug in the SFA code. If we could get a stack
trace from the ION AM then perhaps we could track it down.

Thanks!
Andy

Hi,

we indeed saw this same issue at planetlab Europe, and in a discussion with Thierry and Amine it  seems to be as follows:

=========
Indeed, your slice (urn:publicid:IDN+wall2.ilabt.iminds.be+slice+s1383209922765) is translated into "PlanetLab" slice name : wall2ilabtimindsbe_s1383209922765
which is in fact longer than 32 bytes.
=========

so, in the case below, I guess it is:

chgeninetInstaGENIPlanetLab_Infrastructure
which is longer than 32 chars. (32 chars coming because this is used as login in the PLE nodes, and passwd has this limit if I understood correctly)

In the meantime, however, it is fixed with a workaround I think in PLE.


regards,
Brecht
