I think you need to do this with different volumes. We can't have the same volumes mounted to all the containers. This would mean that all the services are deployed on one common machine, with one filesystem. What we instead want is the following
Machine 1: Master server
Machine 2: Chunkserver 1, Web-A
Machine 3: Chunkserver 2, Web-B.
This means we want 3 separate volumes call them mfsdata_master, mfsdata_chunk1, mfsdata_chunk2. These volumes are mounted to the containers as described above.

Since web-B and chunkserver-2 are on the same machine, update the dependency to just chunkserver 2. It should not depend on chunkserver 1.

Update dependency to just chunkserver 1. See my comments below for more details.

I am still not sure, how these environment variables are populated. Somewhere you will have to specify to the chunkservers how to connect to the master container. Could you please clarify how that is achieved?
There are two services webA and webB, two chunkservers 1&2, webA writes into a file and webB reads the file from the same location.
