So Volume Name: nufa4 . . . Brick1: AAAHOST:/nufa-r4 Brick2: BBBHOST:/nufa-r4b means the files are created in the root file system, in the /nufa-r4 and /nufa-r4b directories of your hosts. I think you have misunderstood 'AAAHOST:/nufa-r4' and 'BBBHOST:/nufa-r4b' as referring to the 2 replica volumes that you have created. They are actually the brick paths. > 2) Whether such a configuration is possible i.e a nufa sitting on top > of 2 replica systems (and in fact how nufa figures out which replica > sit is on the local host). > Nufa makes sense only on distributed volumes. Enabling nufa on a plain replicate volume has no effect- the files will be created on all bricks that constitute the replica.
