Installation on centos 7


(Cameronp) #1

Hi, since centos/redhat runs on 3.10 kernel, orca will not install, even though it seems to indicate in the docs it should be fine.

INFO[0000] Verifying your system is compatible with Orca
FATA[0000] Your kernel version 3.10.0 is too old. Orca requires at least version 3.16.0.

I have 1.9.1 installed, so I did not follow the instructions for that part, and went straight to orca installation.

Any tips?

Thanks

Same issue in RHEL7.2 – kernel 3.10.0-327.el7.x86_64

In the current release of UCP 0.4, we require 3.16 kernel to support the overlay networking driver (cross-host networking) functionality.

If you aren’t able to update your kernel, we will have a release of UCP 0.5 beta shortly that will allow you to use older kernels, including 3.10. However, even with this support for an older kernel, it won’t work with overlay networking. We’re investigating a fix to that for a later time.

Hi,

I ran into the same issue trying to install on some freshly built CentOS 7.1 hosts.

I followed the steps from http://elrepo.org/tiki/tiki-index.php to add their repo , and then install the 4.3 kernel as per http://elrepo.org/tiki/kernel-ml

After rebooting the hosts, the installer will pass the version check and proceed with the install.

Got it working using the 0.5 beta.

Thanks!
