Patrick,
The CentOS version on the machines is 6.8
[lustre@hulk2 ~]$ cat /etc/redhat-release
CentOS release 6.8 (Final)
The kernel version that I have installed is what I found along with the lustre
RPMs
[lustre@amaranth3 ~]$ uname -r
2.6.32-573.12.1.el6_lustre.x86_64
And I am trying to install lustre 2.8.
Should the CentOS release version be 2.7??
