Greetings;

We have received reports recently of users seeing kernel panics when
installing new software, or rebooting after a long time of being in use. In
triaging and debugging this, the root cause seems to relate to a lack of
space in the /boot partition on the node. CentOS changed the way that the
initial partitioning was handled in version 6 of the operating system,
meaning that our project has less ability to control the space allotment
outcome via the installation process, and the result is that the limited
space in /boot can only support a small number of kernels.

We have written some instructions on how to mitigate this on the FAQ site:

http://psps.perfsonar.net/toolkit/FAQs.html#Q72

For now we are recommending that admins check the space available in /boot,
and use yum to remove older kernels that are no longer needed (saving one
backup is always a good idea). Future release announcements will also
feature a reminder of this, until the project can figure out a better
solution to either alarming on this condition, or altering the disk layout so
it is no longer a serious concern.

Thanks for your support of perfSONAR, and please relay any questions you
might have;

-jason
