---------------------------------
Assignee: Mario Kevo
> The region name starting with underscore lead to missing disk store after
> restart
> ---------------------------------------------------------------------------------
>
> 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: needsTriage
>
> 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
> Member Name | Member Id | Disk Store Name | Disk
