Is this a filesystem-wide limit (not more than 32767 files/dirs > total) or a directory-specific limitation (not more than 32767 files/dirs > per dir)? Neither. The limit is "not more than 32767 links on a single inode". The original poster was getting this message when he created 32767 subdirectories off a single parent. "." in the parent has to link to ".." in each child. That's where he's getting his error. I imagine he's getting horrible delays in lookup up files though. Most companies bypass this by creating a multlevel directory tree when they have to manage thousands of users (Netcom's FTP site, for example, puts "bob"'s ftp site in /pub/bo/bob). -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
