perfSONAR User Q&A and Other Discussion

[Scott Bertilson <>]

So, maybe a dumb question, but is your objective to have the installed toolkit run off the USB stick alone with no other disks in the system or are you just trying to get the FullInstall ISO to boot and run off the stick?  It sounded like you were trying to get the toolkit itself to run off the stick, but I wanted to get it clear.  If that's what you were after, one of the sticky points is going to be the enumeration of the drives on the system on which you boot it if there are multiple drives.

I burned a DVD with the FullInstall ISO, booted that and then chose both the options for using the entire USB disk (ended up with the GRUB prompt when I rebooted later from the USB disk).  Then tried formatting the USB
disk with fdisk so that I'd have a pre-existing bootable Linux partition for FullInstall to install into -- also ended up at the GRUB prompt when rebooting later.

Guessing that either it doesn't like my partitions or the GRUB config is munged, but I haven't put too much work into it yet as this was supposed to be something that filled in the spare moments of other projects.  :)

Hi Andrew,

How?d you write the image to the USB disk? I just happened to be reinstalling one of my local boxes, and was able to do it from the Full Install ISO.

Cheers,
Aaron

So I'm not sure if I've done something wrong or what, but I tried to do a FullInstall to a USB disk, then move it to my system and boot.  System is coming up and sitting at a GRUB prompt.  Reformatted my USB, gave it just a partition (instead of the full disk) and didn't move it this time - and I'm still booting to the GRUB prompt.

I used to work with the LiveCD version, USB data for configs, etc. and as that's EOL now I figured I'd start over.

All,

The final version of perfSONAR 3.4 is now available for all users. Version 3.4 includes a number or changes from the 3.3.X versions of the toolkit including:

- A new measurement archive that stores all types of active measurement data. It boasts a new REST interface and significant performance improvements over the previous archive
- A new "full install" distribution similar to the NetInstall but all installed packages are included on the downloaded ISO
- New graphs that can display results from throughput (bwctl+iperf3/iperf) and latency (owamp and ping) tools on the same graph
- First steps toward unifying the projects formerly known as perfSONAR-MDM and perfSONAR-PS into one development effort with the inclusion of the OPPD Measurement Point
- A number of security enhancements including the enabling of automatic updates by default for all new and existing installations
- New documentation at http://docs.perfsonar.net
- ?and much more detailed on our release notes page: http://www.perfsonar.net/release-notes/version-3-4/

A brief summary of how to install perfSONAR 3.4 can be found below:

- Brand new installations may visit http://software.internet2.edu/pS-Performance_Toolkit/ to get the latest ISO images. Please see http://docs.perfsonar.net/install_getting.html for more information on choosing the right distribution and pointers to detailed installation instructions

- For NetInstall users updating from version 3.3.X of the Toolkit you should run "yum update" and then "reboot". Note that all your data will automatically be migrated to the new measurement archive in a background process. See http://docs.perfsonar.net/manage_update.html#special-upgrade-notes for more details

- For NetInstall users updating from version 3.4rc2 or 3.4rc3, run the following:
yum update
yum clean all
yum update
reboot

- For 3.3.X LiveCD/LiveUSB users, note that we are not providing a 3.4 LiveCD/LiveUSB. It is recommended all users transition to one of our other installation types prior to the previously shared EOL date of April 10, 2015. For instructions on how to do so see http://docs.perfsonar.net/manage_update.html#migrating-from-a-3-3-2-livecd-liveusb

- Note that upgrading from versions of perfSONAR older than 3.3 is NOT supported


IMPORTANT NOTE ABOUT AUTOMATIC UPDATES FOR ALL USERS: When you install a brand new toolkit or update from a previous version of the Toolkit, automatic updates will be enabled by default. This means all the packages on your system will be updated on a nightly-basis. Automatic updates will assist in getting the latest packages on your box in a timely fashion. This does not mean you are off the hook for patching your box. Not only will there be a time window of up to 24 hours where you do not receive a patch, but depending on the nature of the vulnerability there may be additional service restarts, system reboots or other tasks required to completely apply a patch. Pay close attention to the the perfsonar-announce mailing list for more details. Also be aware that automatic updates have the potential to grab packages that may break services on your box. The perfSONAR team does not get early access to third-party packages prior to their release (nor are we perfect when it com

es

to our own packages) so this is a very real risk. If a temporary outage caused by an automatic update is a concern for you, then you may consider disabling them. Please see http://docs.perfsonar.net/manage_update.html#automatic-updates for more details on making this decision and how to enable/disable automatic updates.

Hopefully above provides you with all the information you need to get started. Thanks again to all the great user feedback that led to this release and the numerous people that helped test via our release candidates or otherwise. For questions please consult http://docs.perfsonar.net or email .

Thank you,
The perfSONAR Development Team
