perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

All,

This email is to inform you that perfSONAR 4.1 will be released next week on Wednesday August 15th. perfSONAR 4.1 contains a number of changes including:

- A new component called pSConfig to replace the MeshConfig component

- A new TWAMP tool

- Support for docker containers of the “tools" and “testpoint" bundles

For a full list of changes see the release notes here: https://www.perfsonar.net/release-notes/version-4-1

Also note that we are not making 4.1 available on CentOS 6 or Debian 7 (wheezy) since both of these OSes are nearing (or at) their provider's support end of life date. We strongly recommend you update to a supported operating system as soon as possible. Also, BWCTL is not included by default for fresh installs of 4.1, though it will be left untouched on existing systems. For more details on the upgrade process including information about discontinued operating systems, deprecation of BWCTL and exact details of the MeshConfig to pSConfig transition see http://docs.perfsonar.net/release_candidates/4.1b1/manage_update.html#special-upgrade-notes

If you are running a supported operating system and have auto-updates enabled, you should get the new version automatically within 48 hours of the release. There are no manual steps required and all data should be preserved. If for whatever reason you do not wish to receive the update right away you can disable auto-updates using our instructions here: http://docs.perfsonar.net/manage_update.html#managing-automatic-updates-from-the-command-line

Finally, thank you to all the beta testers that have experimented with the software. Your feedback is crucial to a smooth and successful release. We look forward to getting the software to all of you and please let us know if you have any questions between now and the release date. 

Thank you,

The perfSONAR Development team
