[gpfsug-discuss] Biggest file that will fit inside an inode? 3968!!

[Marc A Kaplan]

On a non-SELINUX system the answer is 3968 of data in a 4K inode, just 128 
bytes of metadata.

Caution: it's possible in some future release, this could change ... I 
don't know of any plans, I'm just saying ...

Inode 16346892 [16346892] snap 0 (index 12 in block 255420):
