Editing List of file systems (section)

=== {{Anchor|SHARED}}Shared-disk file systems ===
Shared-disk file systems (also called ''shared-storage file systems'', [[SAN file system]], [[Clustered file system]] or even ''cluster file systems'') are primarily used in a [[storage area network]] where all nodes directly access the [[Block (data storage)|block storage]] where the file system is located. This makes it possible for nodes to fail without affecting access to the file system from the other nodes. Shared-disk file systems are normally used in a [[high-availability cluster]] together with storage on hardware [[RAID]]. Shared-disk file systems normally do not scale over 64 or 128 nodes.

Shared-disk file systems may be [[symmetric]] where [[metadata]] is distributed among the nodes or [[asymmetry|asymmetric]] with centralized [[metadata]] servers.
