This is not really related to elasticluster, but kind of since I need to
attach storage volumes for my cluster.
So maybe people here have some tips anyway.
In my private ansible script I do:
- name: Ensure directories exist
file:
path: "{{ item.path }}"
state: directory
owner: "{{ user_name_grid }}"
group: "{{ group_name_grid }}"
mode: 0755
with_items: "{{ blockstorage }}"
- name: Add mountpoints in fstab
mount:
fstype: "{{ item.fstype }}"
path: "{{ item.path }}"
src: "{{ item.src }}"
state: mounted
with_items: "{{ blockstorage }}"
And I have variables (in /roles/frontend/vars/main.yml)
blockstorage:
- path: '/wlcg'
src: '/dev/sdb'
fstype: 'ext4'
- path: '/grid'
src: '/dev/sdc'
fstype: 'ext4'

helper program, or other error\n In some cases useful info is found

to retry, use: --limit
@/home/centos/grid-uh-cloud/ansible/grid_cluster_setup/frontend.retry
Why do I get this failure? I can loginto the machine and perform the ext4
and mount commands by hand. But I would of course like to avoid that.
