Very astute observation!  Smbtime was removed in 7.1.1 and later and instead the cluster will use the built-in NTP capabilities in a joined domain.  Windows provides this via its own w32time service, so Isilon sets a DC as an NTP source and begins to synchronize from that.  This has been found to be much more reliable than the 6-hour update interval that was had with smbtime.  You can always check ntpq -pn to see the current state of NTP on the cluster, but isi_ntp_config list will not show the DC in its config.  If you desire a different NTP source, you can configure that directly and that will override using an AD DC as NTP source.
Hi all,  does anyone know what happened to smbtime? I can't find the smbtime service in 7.1.1 and 7.2. Neither in the cron nor in isi services. Not that I need it - I just want to make sure it is down.  I wasn't able to find anything in the Documentation / Releasenotes.for 7.1 / 7.1.1  Regards -- sluetze
What happend to smbtime?
