OpenStack Identity (keystone)

Keystone dead but pid file exists

Asked by Tizy

We have an openstack setup running Havana on cent-OS in High Availability mode with 3 controller+storage nodes and one compute node. Network type is nova-network.

After trying to make some keystone-related configuration changes in keystone.conf file, we found that keystone wasn't able to run anymore and we were getting "keystone dead but pid file exists" error messages. We have followed the recommended steps but it still persists.

We tried deleting the pid file in /var/run/keystone/keystone.pid. After deleting the pid file, when the keystone service is restarted, it showed error "keystone dead but subsys locked". To solve this we tried deleting the /var/lock/subsys/keystone file. Then the keystone service is restarted. It is started for the first time. Then when the status of keystone service is checked, it is again showing "keystone dead but pid file exists".

What could be the problem? Kindly help me to resolve this issue.
