Got unify over AFR with scheduler ALU. (gluster 1.4 rc1). volume files-afr1 type cluster/afr subvolumes client1 client2 end-volume volume files-afr2 type cluster/afr subvolumes client3 client4 end-volume volume ns-afr type cluster/afr subvolumes ns1 ns2 end-volume volume files-unify type cluster/unify option namespace ns-afr subvolumes files-afr1 files-afr2 option self-heal background option scheduler alu option alu.limits.min-free-disk 20% Did a test to completely fill up the space on mounted drive, to see what happens. All nodes got filled up to 100% despite the limit of 20% on nodes. Why is this happening ?
