Steps taken:
- MIDAS_Releases, Embedded and Exports files brought across from the previously working SL6 aida-gsi install. Brought as tar balls to preserve ownership
- dhcpd.conf set up with same IP addresses as used on the SL6 install from aida-gsi
- nfs-utils package installed on centos7
- Paths to directories listed in /etc/exports checked that they point to the correct locations on the centos system
- Firewall disabled to confirm that it is not interfering
- setenforce 0 to confirm selinux is not interfering.


- Attachment 1 Screenshot of FEE console for aida04 as it stops booting.
- Attachment 2 text dump of /var/log/messages during the FEE boot sequence
- Attachment 3 text dump from tcpdump filtered to aida04
- Attachment 4 /var/lib/dhcp/dhcp.leases file as mentioned in the /var/log/messages dump
- Attachment 5 A copy of dhcpd.conf
- Attachment 6 A copy of /etc/hosts
- Attachment 7 A copy of /etc/exports    
- Attachment 8 Text dump of ifconfig -a (Note the FEEs are conencted to p4p1)

From the messages dump it seems there is an issue being encountered with dhcp leases for the static IP addresses of the FEEs. They are then getting assigned new IP addresses which are getting put in the leases file.
