I have been using standard RAID 5 on my Dell 2950 III 16Gb RAM server for years without problem.
Recently I decided that I wanted to go the NAS route and move all my files over to ZFS and run my ESXi virtual machines on the NAS via ISCSI. Up to this point my file server was simply a virtualised machine backed up with Syncback to two remote Synology boxes. After looking at what was available I tested Nexenta both with CIFS and ISCSI. Nexenta was fairly easy to setup and I have had the box running for about three weeks now.
I have also decided to also try FreeNAS and have this running with the following configuration.
2950 III server with RAID 1 mirror two 32Gb SSD's on Dell 6i for FreeNAS in PCie x8 port and six 1Tb drives in ZFS RAIDz2 on a Dell 6ir controller in MPT mode. 16Gb RAM is availiable.
My issue it that I either don't understand the NTP model being used or I am missing some configuration. I have a Cisco switch acting as a NTP server for my network and have no problems with any other device or Nexenta getting time synchronisation from it. I cannot get FreeNAS to connect to it either by IPv4 address or by DNS name. In both cases I get "Server could not be reached. Check "Force" to continue regardless." in both cases I can ping the NTP server from the FreeNAS console...

I get the same message if I try to connect to an external time server by IPv4 address.
I have removed all of the pre-assigned NTP servers and left 10.0.0.92 and 3550_ser_12t. As below...
Running cat /etc/ntp.conf from the freenas console gives me the configuration that I expect.
[root@freenas ~]# cat /etc/ntp.conf
server 10.0.0.92 iburst maxpoll 10 minpoll 6

# XXX: this doesn't work as documented
#restrict default ignore
restrict 127.0.0.1

Running ntp -q results in what looks like a working connection. I am very new to freeBSD so confess to being a NEWB this error of Server could not be reached. Check "Force" to continue regardless threw me for quite a while.

runnning ntpdate shows the socket in use I don't know what to expect here.
[root@freenas ~]# ntpdate 3550_ser_12t.the-hedges.com
26 Jun 16:33:55 ntpdate[8153]: the NTP socket is in use, exiting
[root@freenas ~]#
I also noted that under the CIFS connection that Time Server for Domain was checked I have unchecked this as I don't want the FreeNAS system acting as my main time server. CIFS is in workgroup mode for now.
Could someone please update me on what is happening with regard to server could not being reached. I had to force it but had no idea at this stage that it was working. It was only after running shell commands that I realised all was probably OK. It also looks to me that it would not work at all if using a straight IPv4 address. Note I have a local DNS server with A records for key equipment including the tome server switch.
Thank you.
