[Gluster-devel] [Gluster-users] cluster.min-free-disk is not working in distributed disperse volume

[Susant Palai]

Hi,
  Cluster.min-free-disk controls new file creation on the bricks. If you happen to write to the existing files on the brick and that is leading to brick getting full, then most probably you should run a rebalance.

Regards,
Susant

Hi, 


I have a cluster of 720 bricks, all bricks are 4TB in size. I have change the cluster.min-free-disk default value 10% to 3%. So all the disks should have 3% minimum disk space free. But some cluster disks are getting full now. Is there any additional configuration for keeping some percentage of disk space kept free?

Any help will be greatly appreciated.
