Local /etc/systemd/system/ntpd.service
There is a local modification to ntpd.service (attached) which serves to ensure that ntpd doesn't start until the network is up, even if ntpdate has been disabled.
I can't see how this could cause a problem, but it is attached just in case.
ntpd.service and ntpdate.service are both owned by the "ntp" source package. If there exists and ordering requirement, it should be expressed in the unit file. Reassigning. s/and ordering requirement/an ordering requirement/ (In reply to comment #6) > ntpd.service and ntpdate.service are both owned by the "ntp" source package. If > there exists and ordering requirement, it should be expressed in the unit file. > Reassigning. Except that, as far as I can see, the unit files for ntpd and ntpdate already have the ordering relationship. ntpd.service has: After=syslog.target ntpdate.service It just doesn't seem to take effect. hm, I see. I wonder what causes the following jobs to be enqueued: [ 40.786960] systemd[1]: Trying to enqueue job systemd-update-utmp-runlevel.service/start/ignore-requirements [ 40.787212] systemd[1]: Trying to enqueue job multi-user.target/start/ignore-requirements [ 40.787272] systemd[1]: Trying to enqueue job getty/start/ignore-requirements [ 40.787551] systemd[1]: Trying to enqueue job getty.target/start/ignore-requirements [ 40.787799] systemd[1]: Trying to enqueue job ntpdate.service/start/ignore-requirements [ 41.641098] systemd[1]: Trying to enqueue job systemd-update-utmp-runlevel.service/start/ignore-requirements [ 41.641137] systemd[1]: Trying to enqueue job multi-user.target/start/ignore-requirements [ 41.641401] systemd[1]: Trying to enqueue job ntpdate.service/start/ignore-requirements It could come from unit deserialization, but I see no indication in the log of that happening. In case we're missing some log items... Could you please boot with: systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M and attach the new output of dmesg. Thanks.

dmesg ouput with increase log_buf_len
OK. Here is the new dmesg output corresponding to the /proc/cmdline:
root=nfs:fs.beware.dropbear.id.au:/export/NFSroots/Fedora16 initrd=/images/Fedora16/initramfs-3.1.6-1.fc16.i686.img selinux=0 systemd.unit=multi-user.target systemd.log_level=debug systemd.log_level=debug systemd.log_target=kmsg log_buf_len=1M BOOT_IMAGE=/images/Fedora16/vmlinuz-3.1.6-1.fc16.i686
The "ignore-requirements" lines seems to have gone away but the mis-ordering of ntpdate remains.
Thanks. [ 29.919074] systemd[1]: Accepted connection on private bus. [ 29.919963] systemd[1]: Got D-Bus request: org.freedesktop.systemd1.Manager.TryRestartUnit() on /org/freedesktop/systemd1 [ 29.920036] systemd[1]: Trying to enqueue job ntpd.service/try-restart/replace [ 29.920135] systemd[1]: Installed new job ntpd.service/restart as 131 [ 29.920153] systemd[1]: Enqueued job ntpd.service/try-restart as 131 [ 29.921607] systemd[1]: About to execute: /usr/sbin/ntpd -n -u ntp:ntp $OPTIONS This is probably /etc/dhcp/dhclient.d/ntp.sh calling "systemctl try-restart ntpd.service". It exposes a bug in systemd that we previously encountered with ypbind. *** This bug has been marked as a duplicate of bug 753586 *** |
Created attachment 579183 [details] The output of cat /proc/cmdline Description of problem: I find that time is not synchronised (especially on a reboot after daylight saving change) due to ntpdate failing. Version-Release number of selected component (if applicable): ntpdate-4.2.6p4-1.fc16.i686 How reproducible: Always Steps to Reproduce: 1.grep /var/log/messages for ntpdate 2. 3. Actual results: ntpdate[nnn]: the NTP socket is in use, exiting Expected results: ntpdate should run successfully Additional info: I booted with systemd.log_level=debug and saved the output of dmesg (attached). ntpd is clearly being started before ntpdate but I can't see why. If I manually stop ntpd.service, start ntpdate.service and start ntpd.service things work as expected. As this seems to be a problem with the systemctl configuration I have attached the appropriate files.
