Hi,

Questions prefixed with Q: inline below:

Additional information:
* Time synchronization installation was skipped. Please note that
unsynchronized time on server instances might be problem for some
OpenStack components.

*Q: Do i need to sue ntpd to ensure all my systems are in sync, whats
the recommended way here ?*

All your nodes need to have the correct time. You can specify an NTP server in the Packstack answer file or as a CLI option and then Packstack will configure your nodes to use that NTP server. If you don't specify an NTP server then Packstack doesn't handle NTP so you will have to do it yourself. Either way, make sure that all nodes always have the correct time.

FWIW, i did the below and re-ran my packstack:

CONFIG_NTP_SERVERS= <my intranet's time server> in my answers file

# packstack --answer-file ./packstack-answers.txt

It showed ...

...

Installing time synchronization via NTP [ DONE ]

Now checking on my nodes, I don't still see NTP service running...

[root@rhsdev4 ~]# ps aux| grep ntp
root     20433 0.0 0.0 112640   960 pts/0    S+   13:58   0:00 grep --color=auto ntp

[root@rhsdev4 ~]# systemctl status ntpd.service
ntpd.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

[root@rhsdev4 ~]# systemctl status ntpdate.service
ntpdate.service - Set time via NTP
   Loaded: loaded (/usr/lib/systemd/system/ntpdate.service; disabled)
   Active: inactive (dead)

Now what did i do wrong ? :)

thanx,
