It seems to calculate hash value based on its parent directory. For example, I have 3 bricks, br1, br2, br3 and each has 100G. And I''m going to more files on the following two directories, one is 10G and the other is 150G /aa/* (thousand files total 10G) /bb/* (tens of thousand files total 150G) If files in /aa/ is mapped to br1 and /bb/ is mapped to br2, would the overflowing 50G of /bb/ be stored at one of free spaces in br1 or br3? (min-free-disk is 0 for easier example) If it is supported, how GFS can fine the overflowing files with O(1). Otherwise, total size of a directory might be much smaller than one brick size. (many directories can use same brick) <http://www.gluster.org/docs/index.php/Understanding_DHT_Translator>Min Thanks --0016368325a87da4b8046be0b305 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <div class=3D"gmail_quote">[Sorry I'm resending this message because I didn't follow the title convention]</div><div class=3D"gmail_quote"><br>Hello,<div><br></div><div>I'm a newbie at the GlusterFS.=A0</div><div>=
