B node brick:/data/brick/gv0 reproduce step: 1. gluster peer probe 128.224.162.255 //run on A node 2.gluster volume create gv0 128.224.162.163 : /data/brick/gv0 force //run on A node 3.gluster volume start gv0 //run on A node 4. mount -t glusterfs 128.224.162.163:/gv0 gluster //run on A node 5.create some file(a,b,c) in directory gluster //run on A node 6. gluster volume add-brick gv0 replica 2 128.224.162.255:/data/brick/gv0 force //run on A node 7. create some file(d,e,f) in directory gluster //run on A node 8. mount -t glusterfs 128.224.162.163:/gv0 gluster //run on B node 9.ls gluster //run on B node My question is as below. After step 6, the volume type is change from distribute to replicate. The file (a,b,c) is created when the volume type is distribute. The file (d,e,f) is created when the volume type is replicate. >>After step 6, does the volume will replicate the file (a,b,c) in two brick?Or it just replicate the file(d,e,f) in two brick? If I run "gluster volume heal gv0 full", does the volume will replicate the file (a,b,c) in two brick? After step 6 volume have converted to replicate volume. So if you create file from mount point it will replicate these file to all replica set. In your case after step 6 it will replicate only file(d,e,f) because before step 6 volume was distributed. For replicating all the file (before step 6) you need to run #gluster volume heal <volname> full. After executing this command file in both replica set should be same.
