Help with Analyzing NFS Architecture in a Cluster Sharing a Home Directory Across Two Servers"

I Am very confused because I am trying to understand the architecture without documentation,we have a NFS architecture of a cluster of PCs that share the same home directory ( Server1 is a Pc of a cluster ) and every user has a home in the Server 2 used for a specific purpose from the users. I've collected the following information from both servers: Server 1: Output of cat /etc/exports > /disk28 172.16.13.115(rw) 172.16.13.114(rw) ....etc Output of showmount -e N/A cat /etc/fstab > 172.16.15.20:/disk38 /disk38 nfs defaults,bg,rw 0 0 172.16.15.17:/disk36 /disk36 nfs defaults,bg,rw 0 0 ...etc Server 2: Output of cat /etc/exports >/home 172.16.14.86(rw) 172.16.37.221(rw) 172.16.11.30(rw) 172.16.11.51(rw) 172.16.37.222(rw) 172.16.37.219(rw) 172.16.37.253(rw) 172.16.10.154(rw) 172.16.11.219(rw) 172.16.12.16(rw) 172.16.12.20(rw) 172.16.12.32(rw) 172.16.12.40(rw) 172.16.12.125(rw) 172.16.12.126(rw) 172.16.12.127(rw) ...etc Output of showmount -a >All mount points on a.server: 172.16.11.219:/home 172.16.11.30:/home 172.16.11.51:/home 172.16.12.125:/home 172.16.12.126:/home 172.16.12.127:/home ...etc cat /etc/fstab >/dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 none /dev/pts devpts gid=5,mode=620 0 0 none /dev/shm tmpfs defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 /dev/hda /media/cdrom auto pamconsole,fscontext=system_u:object_r:removable_t,exec,noauto,managed 0 0 Now, I'd like to comprehend how these servers are configured to share the home directory and how the interaction between the cluster PCs and these NFS servers works. What specific details should I be looking for in these outputs to get a complete picture of the NFS architecture? Thanks in advance for any help or insights you can provide. I'm willing to share the full outputs if needed.
