Here is a scenario that I was just asked about:
NFS Server A exports /data
NFS Server B exports /data
Several client servers mount /data
The questions are:
How to keep NFS Server A and B in sync
On the client servers, if NFS Server A is down, how to mount /data from
NFS Server B (and vice

availability and the storage may not be share-able .
but yes - it is an HA cluster
