Hello!
I am trying to set up an OpenStack cluster but I am not having much
success. I have been fighting it for several weeks thus my decision
to join this list.
I have 4 hosts all running CentOS 7:
infra1 (Celeron J1900 CPU [4core, 2Ghz], 8GB RAM, 120GB SSD)
compute1 (Core i7 CPU [4core, 4Ghz], 16GB RAM, 120GB SSD)
log1 (AMD Athlon CPU [2core, 2Ghz], 3GB RAM, 120GB HDD)
storage1 (Xeon E3 CPU [4core, 2Ghz], 8GB RAM, 8TB RAID10)
Considering the none-too-powerful specs of infra1 and log1 I have
set the following services to run on metal:
aodh_container
ceilometer_central_container
cinder_api_container
cinder_scheduler_container
galera_container
glance_container
gnocchi_container
heat_apis_container
heat_engine_container
horizon_container
keystone_container
memcached_container
neutron_agents_container
neutron_server_container
nova_api_metadata_container
nova_api_os_compute_container
nova_api_placement_container
nova_conductor_container
nova_console_container
nova_scheduler_container
rabbit_mq_container
repo_container
rsyslog_container
When I run setup_hosts.yml I get errors on infra1. The specific
errors vary each time but it generally seems to fail with container
creation.
