Cluster File System • Same view from each member • Client/Server (in most cases) − Each file system or AdvFS domain is served by one cluster member − A member can be a client for some domains and a server for others − A member can transition between roles transparently − Server coordinates caches, meta-data updates • Client reads directly from storage, writes through server • Full X/OPEN, POSIX file system semantics with binary compatibility 16
Cluster File System • Cluster-wide cache coherency • Transparent file system failover and recovery • Integrated with Cluster Alias for NFS server 17
