>
> Key: GEODE-9969
> URL: https://issues.apache.org/jira/browse/GEODE-9969
> Project: Geode
> Issue Type: Bug
> Components: regions
> Affects Versions: 1.12.8, 1.13.6, 1.14.2, 1.15.0
> Reporter: Mario Kevo
> Assignee: Mario Kevo
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> The problem is when using the region with a name starting with an underscore(allowed by documentation [region_naming|https://geode.apache.org/docs/guide/114/basic_config/data_regions/region_naming.html]).
> 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
> {code:java}
> gfsh>list disk-stores
