I am trying to install openstack ocata on rhel 7.1 using packstack. I am using the following link for installation: The installation gets stuck at the step showing the message "Testing if puppet apply is finished". Can anyone help me to solve this issue?

If you can provide log entries, that will be very helpful in getting to the bottom of this.

there is no packstack folder in var/log/ directory so there is only openstack-setup.log which i found out in /var/tmp/packstack/ folder.

For how long have you waited? That "Testing if puppet apply is finished" process takes a long time depending on your hardware.

I have waited for more than 4 hours

Tried the same thing last night: after 2,5 hours puppet was still busy: System spec: - i7 4700MQ - 1 TB 7200RPM disk - 8 GB RAM - RHEL 7.3 clean install of "server + gui" - Wifi network (its a laptop)

ran packstack --allinone

According to "top" system started swapping after 50 minutes or so, having absorbed all RAM. Top memory users being puppet (6%) and *-api processes at around 2% each. 17 nova-api processes running at the same time. Total number of processes present on the box above 450.

/var/lib shows dirs being added (nova, cinder, redis, gnocci etc) until swapping starts

Last entries in the openstack-setup.log are:
cd /usr/share/openstack-puppet/modules
tar --dereference -cpzf - aodh apache ceilometer certmonger cinder concat firewall glance gnocchi heat horizon inifile ironic keystone magnum manila memcached mongodb mysql neutron nova nssdb openstack openstacklib oslo packstack panko rabbitmq redis remote rsync sahara ssh stdlib swift sysctl tempest trove vcsrepo vswitch xinetd | ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@ tar -C /var/tmp/packstack/dc47e9fea0d74bd99031dad3e64afce4/modules -xpzf -

Ok, think I found the issue..
looking .at /etc/nova/nova.conf
#Number of workers for OpenStack API service. The default will be the number
# of CPUs available.
As the CPU has 8 hyperthreads, RHEL is reporting it as 8 cores. This explains the explosion in processes

ideally the --allinone should put in sensible limits as all processes will be running a single node.

@jklu what should be the value set for number of workers for openstack API service?

Got my All In One setup working by specifying: CONFIG_SERVICE_WORKERS=1 in the packstack answer file

On my setup it takes packstack about 35 mins to complete

Some of the repos were missing and after enabling those repos the packstack installation completes. To find which repos are missing check the log files in manifests folder in /var/tmp/packstack/instal_folder_timestamp_directory/manifests/ directory

There is a possibility that the server doesn't have enough memory. Check the RAM size during the installation. Recommended size is 5 to 6GB. Also, check whether the NetworkManager and firewalld is disabled. You can check logs under /var/tmp/packstack/ which will give pointers if the issue is otherwise.

ram allocated is 10 gb and firewall and network manager are disabled. which directory should I look into for issues?
