---------------------------------
Summary: 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: 1.14.2, 1.13.6, 1.12.8, 1.15.0
Reporter: Mario Kevo
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

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:
