[gpfsug-discuss] default inode size - remarks

[Marc A Kaplan]

You can set inode size to any one of 512, 1024, 2048 or 4096 when you 
mmcrfs.  Try it on a test system.

You want all the metadata of a file to fit into the inode. Also small 
files, and small directories, can be stored in their inodes.

On a test file system you can examine how much of an inode is occupied 
with which data and metadata using the 
inode subcommand of the tsdbfs command.  (Root only, and usual cautions -- 
use only to look, if you make a mistake patching - I told you not to do 
that!)

inode number of any path is easily discovered with the standard 

ls -ild pathname 

command
