Setup guide

The default inode ratio is 2048. The minimum value is 512 and the maximum value is 6656. The inode ratio
is rounded up to the nearest 512 KB multiple (i.e. 513 rounds up to 1024). Generally, the number of inodes
is related to the frame size of your most common production format and the size of your Stone partition.
NOTE The maximum size of a Stone filesystem is 8 terabytes.
For help entering the inode ratio parameter during storage configuration, refer to the chapter “Creating the
Stone Filesystem” in the Stone and Wire Filesystem and Networking Guide.
