I am trying to create a Ignite Cache with persistence for Sets of Model. That is, IgniteCache<String, Set<Model>>.
While running it locally, everything works. I can restart the application and Ignite loads its persisted database.
But when running with Docker or Kubernetes (with mounted volume for persistence) I cannot restart the application. Otherwise I get this error:

I created a GitHub repo to make it easy to test... https://github.com/jesjobom/ignite-persistence-test/
Main configuration:
System.setProperty(IgniteSystemProperties.IGNITE_NO_SHUTDOWN_HOOK, "true");
IgniteConfiguration igniteConfiguration = new IgniteConfiguration();
//Region for persistent (in disk) data
DataRegionConfiguration persistence = new DataRegionConfiguration().setPersistenceEnabled(true)
.setInitialSize(64 * 1024 * 1024)
.setMaxSize(128 * 1024 * 1024).setName(PERSISTENT_REGION_NAME);
DataStorageConfiguration dataStorageConfiguration = new DataStorageConfiguration().setDefaultDataRegionConfiguration(persistence);
//Persistence location config
dataStorageConfiguration.setWalPath(STORAGE_LOCATION + "/wal")
.setWalArchivePath(STORAGE_LOCATION + "/wal-arc")
.setStoragePath(STORAGE_LOCATION + "/store");
igniteConfiguration.setDataStorageConfiguration(dataStorageConfiguration);
ignite = Ignition.getOrStart(igniteConfiguration);
ignite.cluster().active(true);
store = ignite.getOrCreateCache(new CacheConfiguration<String, Set<Model>>()
.setDataRegionName(PERSISTENT_REGION_NAME)
.setCacheMode(CacheMode.REPLICATED)
.setAtomicityMode(CacheAtomicityMode.TRANSACTIONAL)
.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC)
.setName("store")
.setIndexedTypes(String.class, Set.class)
);
It looks like IGNITE_HOME directory refers to a volume/folder that is cleared on restarts. Please set that variable to a path that is not changed over restarts the way you did for the storage and WAL.
