Description
The problem is when using the region with a name starting with an underscore(allowed by documentation region_naming).
If we stop one of the members and then rename the working dir(include disk store dir) to some new name and start the server with the name like renamed working dir, it will lead that we have the same disk-store-id in the listed disk-stores and in the missing disk store.
This happens only if we are using the region with an underscore at the beginning.
Steps to reproduce:
Run locator and 4 servers, create region with name starting by underscore
- start locator --name=locator
- start server --name=server1 --server-port=40401
- start server --name=server2 --server-port=40402
- start server --name=server3 --server-port=40403
- start server --name=server4 --server-port=40404
- create region --name=_test-region --type=PARTITION_REDUNDANT_PERSISTENT --redundant-copies=1 --total-num-buckets=10 --enable-synchronous-disk=false
- query --query="select * from /_test-region"
From another terminal (Kill server and rename working dir)
- kill -9 $(cat server4/vf.gf.server.pid)
- mv server4/ server5

Start a new server with a name like you rename your working dir from the restarted server.
- start server --name=server5 --server-port=40405
Now we have the following output:
