Upgrading node GLIBC issue

[kserradell]

In collaboration with @pabretonniere, we are trying to update esgf.bsc.es data node (v2.8.1-master-release) with esgf-ansible procedure but we are having a major issue.

This method seems to be currently broken for a CentOS 6.9 node. Conda installs a python version without glibc 2.12 support and consequently, fails.

We tried to upgrade from 6.9 to 7 but the upgrade crashed (we add a snapshot of the VM so we can easily roll back).

We need to update the node to solve a publisher issue but we are currently stuck. Any advice?

Thank you!

Replace the following part of line 9 in roles/conda/tasks/main.yml:

url: https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh

with:

url: https://repo.anaconda.com/miniconda/Miniconda3-py38_4.8.3-Linux-x86_64.sh

This fixed my error. Maybe you also need to delete the current conda installation (at your own risk, i'm installing on a fresh machine) and remove the old script at /tmp/Miniconda3-latest-Linux-x86_64.sh beforehand. This will install Conda 4.8 directly with Python 3.8.
