8703.0. "Maximum number of files supported by UFS & NFS?" by PRIME8::GUILES () Tue Feb 04 1997 15:32

What is the maximum number of files supported on a UFS file system on
Digital UNIX V4.*?

Does NFS V3 support whatever the underlying file system supports?

(This info for UFS wasn't in Appendix A in the Digital UNIX 4.0B Release Notes. 
It was there for AdvFS.)

A big part of this question is how much disk space do you have...

In general, you also don't place all files in a single directory
or file system for performance reasons.

In short, this question seems to be a red-herring to solving any
business problem...what is it that the customer is trying to do?

	For UFS the maximum inode number is 4,294,967,295 since the
	type of the inode number an unsigned int.  This will pretty
	solidly limit the number of files on a single file system
	for all that it is a lot.

Thanks for the input, but I'm already aware of such storage and practical
limits. I'm responding to an RFP and just need to be able to support a minimum
of up to 500,000 file entries on a file system. Since we theoretically support
2**32 on UFS, I can state that we exceed the requirement (with both UFS & AdvFS).
