I understand hard linked files are a logical problem for applying tree quotas. However, I don't think such a problem should kill the whole implementation! I'm happy with any solution, even if counting the file multiple times was picked as the conservative solution. Who uses hard links that much anyway. I hope that's not the only thing stopping a tree quotas implementation That's the only implementation I could find, doesn't look too up2date though <a href="http://cgi.cse.unsw.edu.au/~neilb/wiki/">http://cgi.cse.unsw.edu.au/~neilb/wiki/</a> <div> On 3/22/07, Horst H. von Brand <<a href="mailto:vonbrand@inf.utfsm.cl">vonbrand@inf.utfsm.cl</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Lamont Peterson <<a href="mailto:lamont@gurulabs.com">lamont@gurulabs.com</a>> wrote: > On Wednesday 21 March 2007 02:14am, Ahmed Kamal wrote: > > Coming from a systems administration background, I was very surprised to > > find out that fedora (well Linux actually) doesn't have a per directory > > quota.

You're asking for what's > called "tree quotas" support. And that is nonsense, as a file /doesn't/ exist "in a directory", the directory only holds the name and a reference to the actual file. So, a file can exist under many different names in assorted directories (hard links). How do you acount for that? Can't count it N times if there are N links, but if you count each link 1/N, deleting stuff here may get you past quota elsewhere (even other people who happen to link to the same file).
