Re: Ext3 File System "Too many files" with snort

[harlan@artselect.com (Pete Harlan)]

Reiser3 lets a directory have more than 32000 subdirectories already.
I ran into this problem two weeks ago on an ext3 filesystem and found
Reiser didn't have the problem.  My reiser3 directory had 1million+
subdirs before I killed my test program.

I believe it still has a similar limit on the number of hard links,
but it doesn't implement ".." as a hard link.
