glusterfs.git/tests/basic/posix/shared-statfs.t, branch v3.12.5 GlusterFS is a distributed file-system capable of scaling to several petabytes. It aggregates various storage bricks over Infiniband RDMA or TCP/IP interconnect into one large parallel network file system. posix: option to handle the shared bricks for statvfs() 2017-07-31T15:34:58+00:00 Amar Tumballi amarts@redhat.com 2017-06-23T07:40:56+00:00 61ea2a44b509cebc566fc18b2c356d88a3f1fdc8 Currently 'storage/posix' xlator has an option called option `export-statfs-size no`, which exports zero as values for few fields in `struct statvfs`. In a case of backend brick shared between multiple brick processes, the values of these variables should be `field_value / number-of-bricks-at-node`. This way, even the issue of 'min-free-disk' etc at different layers would also be handled properly when the statfs() sys call is made.
