perfSONAR User Q&A and Other Discussion

Andrew –

 

We do not use IPv6 here.  However, during the install I do not configure the network card.  Perhaps your ISO has some default IPv6 settings?.  After the system boots up, the first thing I do is configure the networking scripts, which are exclusively IPv4.  I also disable references to IPv6 but apparently this comes too late.  I will try your suggestions later today and let you know what I find.  Thank you.

The Django error is new, so we can dig closer at that. 

Actually I was looking at the stacktrace wrong, the Cassandra connect exception is part of the Django stacktrace (I was reading it as two different things initially, doh). That means we are likely hitting the known cassandra IPv6 only issue. The real question now becomes if your hosts indeed booted with an IPv4 address, why is it still failing.  If not, either assigning one one or following the FAQ should be the fix.
