maximum number of hard links

hydraMax · 12-08-2010, 12:19 AM

I have a 32-bit Linux server with an ext3 file system. Is there any kind of upper-limit to the number of hard links I am allowed to use? (Per inode...? Per directory...? Per filesystem...?)

And (just out of curiosity) would this be any different if I had a 64-bit machine or a different file system?

Hi,

I found this from Wiki:

Quote:

The maximum number of hard links to a single file is limited by the size of the reference counter: ... On Unix-like systems the counter is usually machine-word-sized (32 or 64-bit: 4294967296 or 18446744073709551616 links, respectively).
