Hi, Environment: OS : Windows 64-bit ElasticSearch : 6.6.2 Java: 1.8.151 Cluster: Single Node cluster Index strategy: Indices are created daily and programmatically Shard: Single shard per index and no replication We have been using elasticsearch for more than a month. The machine contains approximately 30 indices (data for 30 days). Total size of all the indices is around 100s of GBs. ```auto [2019-04-19T10:28:40,735][WARN][o.e.e.NodeEnvironment] [Heqvpo8] lock assertion failed java.io.IOException: The device is not ready at sun.nio.ch.FileDispatcherImpl.size0(Native Method) ~[?:?] at sun.nio.ch.FileDispatcherImpl.size(FileDispatcherImpl.java:97) ~[?:?] at sun.nio.ch.FileChannelImpl.size(FileChannelImpl.java:310) ~[?:?] at org.apache.lucene.store.NativeFSLockFactory$NativeFSLock.ensureValid(NativeFSLockFactory.java:182) ~[lucene-core-7.6.0.jar:7.6.0 719cde97f84640faa1e3525690d262946571245f -

This issue happens every time I restart the machine. The workaround is to restart elasticsearch service. What is the root cause of this error? ---

> [@HPVRNP](#): > > `java.io.IOException: The device is not ready` It looks like you're starting up Elasticsearch before the storage device is ready. ---

The service is running in Auto mode (Windows elastic service). So it tries to start on system boot. ---
