perfSONAR User Q&A and Other Discussion

[Paul Gray <>]

Greetings --- I apologize for the repeat inquiry, but was wondering if 
anyone had an update.

Specifically, by any chance has someone verified that the SQL MA can 
successfully be deployed with the perfSONAR 3.3 MDM image?  I've heard 
of several people reporting failures off-list and was wondering if 
anyone has been able to finish the plumbing of the the SQL MA 
configuration with the latest Debian-based DVD iso.
