1.7 Upper Limits of the File System

The following table lists the upper limits of the GFS Shared File System on a file system basis:

[Table Upper limits of file system]

Item	Upper limit
Maximum file system capacity	Below 1 terabyte (1 terabyte per one partition)
Maximum file size	Below 1 terabyte
Maximum number of sharable nodes	2 nodes
Maximum directory size	Below 2 gigabytes
Maximum number of partitions consisting of a file system	1 partitions
Maximum number of i-nodes per file system	16 mega
Maximum number of directories per file system	1 mega

The maximum number of GFS Shared File Systems in a cluster system is 10.

We recommend to lessen the number of the GFS Shared File Systems simultaneously used in one cluster system as much as possible. When you use many GFS Shared File Systems, please carry a sufficient number for a node of CPUs, and carry out system verification in advance.
