  • 1.  How do I install DPDK modules?

    Posted 02-12-2018 00:00
    I am seeing an error message at system startup (and in the output of systemctl status 128T) that says the following: [Start code block] Feb 12 16:41:35 ip-10-0-2-231.ec2.internal dpdkcheck[3176]: DPDK modules are not installed for this kernel Feb 12 16:41:35 ip-10-0-2-231.ec2.internal systemd[1]: 128T.service: control process exited, code=exited status=1 [End code block]128T software won't start for me. How do I go about getting this installed?

    Uh oh! That error likely means that your DPDK module and your kernel version aren't compatible with one another. If you download CentOS from their website it'll have a newer kernel than the one 128T needs. The 128T installer should downgrade the kernel to be compatible with the DPDK modules that it requires. Did something happen during installation to prevent the kernel downgrade from completing properly? Try the following:

     

    [root@labsystem1 ~]# uname -r 3.10.0-514.2.2.el7.x86_64

    Your kernel should also be 3.10.0-514...

    Thanks for replying... yeah, the installation was interrupted and the kernel on my was newer than 3.10.0-514. I reinstalled 128T and things are much happier now.
