I THINK I have this sorted out. 2 possible issues. First, I needed to run "signal-event fstab-update". Part of the problem may have been a latency issue on the FreeNAS server i was mounting using cifs. Here is my fstab entry. It seems to be working now:
/dev/mapper/VolGroup-lv_root / xfs defaults,acl,user_xattr 0 0
/dev/mapper VolGroup-lv_swap swap swap defaults 0 0
//(server name)/homes /nasuserroot cifs credentials=/root/freenas_drive,vers=3.0,netdev,comment=systemd.automount,sec=ntlm,filemode=0775,dir_mode=0775,uid=0,gid=0
/nasuserroot/nethserver/ibay /var/lib/nethserver/ibay none defaults,bind 0 0
/nasuserroot/nethserver/home /var/lib/nethserver/home none defaults,bind 0 0
Hope that is useful for anyone looking to do this. If this is a bit of a hack and someone knows a better way, please post it here so we are all the wiser. Thanks all.
