What is the maximum size of a GFS file system?

GFS 6.1 (on RHEL 4) supports 16TB when any node in the cluster is running 32 bit RHEL. If all nodes in the cluster are 64-bit RHEL (x86-64, ia64) then the theoretical maximum is 8 EB (exabytes). We have field reports of 45 and 50 TB file systems. Testing these configurations is difficult due to our lack of access to very large array systems.
