Which version of Docker is the node running on?
Also which command did you use to install DTR?

(Patrick Devine) #3

I’m assuming you’re using a copy of RHEL 7.2 w/ kernel ~3.10.0-327. There’s a bug in that kernel which has been patched by Red Hat. I believe you can get this to work by just upgrading your kernel ala sudo yum update -y kernel. Once you’ve upgraded the kernel, reboot and you should be able to install.

Hello Nicolas, Following are the details you asked for:

Docker version 17.03.2-ee-4, build 1e6d71e

I used two commands to install the DTR.

  1. I ran the following command on the UCP manager Node:
    docker run -it --rm
    docker/dtr:2.2.6 install

  2. After the above command failed, I tried the following command on the node, where DTR is being deployed. I got this command from the DDC in Sandbox install.

docker run -it --rm docker/dtr install
–ucp-node node2

Hello Patrick,
Yes I am using the following version of kernel:
cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)

Also I will do the update kernel and will let you know whether I am able to install DTR.

Hello Patrick,
updating the kernel as per you suggested, made the DTR install successful.

Really appreciate your help…Thank you all :slight_smile:

Hey Jaron,

Glad it worked for you! I’m going to see if we can detect the kernel version in the future and give you a warning/explanation on how to fix it.

Hi parvez84,

You just need to sudo yum update -y kernel, reboot and then install should work fine.
