Yes, min-free-disk option to dht works. But please note following points 1. Availability of disk space is checked only during creation of new files. If the disk space availability falls below configured limit, writes to files already on disk will continue without any warnings/errors. 2. If the subvolume on which the file being created (hashed subvolume), has free disk space less than min-free-disk, the file will be created on the node which has maximum free disk among all the children. Note that the file will be created even though this node has less than the min-free-disk space. Please note that, dht does not treat non-availability of min-free-disk of disk space as an error. On the other hand it tries its best to spread the files to other nodes, when the hashed subvolume does not have required space. regards, Raghavendra. ----- Original Message ----- From: "eagleeyes" <eagleeyes at 126.com> To: "gluster-users" <gluster-users at gluster.org> Sent: Monday, July 27, 2009 9:28:55 AM GMT +04:00 Abu Dhabi / Muscat Subject: Question of min-free-disk Hi Did the option min-free-disk can work ?
