[Gluster-users] If a file grows bigger and bigger, how can glusterfs move it between bricks?

[Raghavendra G]

Hi Kirby,

As of now, dht does balancing of storage only during creation of files.
Files which are already created are not moved b/w nodes because of less free
storage.

During creation dht tries to balance out the storage b/w its children. it
accepts an option min-free-disk which is nothing but the minimum percentage
of disk space on a node needed for dht to store the file on that node. If
the hashed node does not satisfy this criteria, dht stores the actual file
on any node which has minimum percentage of free disk configured and stores
the a pointer to this node in the hashed node.

regards,
