Fix partitions on CI slaves , some are missing /var/lib/docker
Open, NormalPublic


Some integration-slave-docker instances have been provisioned with a /var/lib/docker partition but others do not. It is a bit confusing.

$ sudo cumin --trace --force 'name:docker' 'mount -t ext4|sort'
13 hosts will be targeted:

Or in short, the following instances lack a /var/lib/docker dedicated partition:


Maybe because they predate the introduction of /var/lib/docker and puppet is unable to magically shuffle the partitions for us. In which case we would have to provision new instances and delete those.

That is set by profile::ci::dockervolume which comes from df1dc5957edce36b12909b3e8bd8cc1b8935fb44 by @dduvall

I have added two Jenkins slaves with role::ci::slave::labs::docker with $docker_lvm_volume = true. One had a sub partition /var/lib/docker the other did not :]
