@mahoboy468 Any chance you did upgrade the `crate` package recently? Maybe happened during the reboot? When was your CrateDB cluster set up originally (rough timeframe)? ---

@jayeff No, it has not been updated. system worked fine, i think database files crashed after reboot. Can it be reindex or create new node folder and move prev node files to new node? ---

@mahoboy468 It’s difficult to tell what potentially happened or how to proceed without having much insight into your setup. You could try to move away the data-folders and start with a fresh, empty data-folder. If you have a backup you could potentially restore the files from the backup. If your tables are replicated CrateDB would restore the data from the replica automatically. ---

@jayeff system have 1 node, and i haven’t backup or snapshot i try this step and crate start fine without data, and Crate create nodes folder automatically ```auto mv /var/lib/crate/nodes /var/lib/crate/nodes_org systemctl start crate ``` so, ```auto systemctl stop crate mv /var/lib/crate/nodes_org/0/indices /var/lib/crate/nodes/0/ systemctl start crate ``` crate started, but not show any data Can i fix this problem only with indices folder and without old \_state folder ? ---

@mahoboy468 without backup or another node with replicated data I don’t know if you have a chance of restoring your data 😬 ---

I am sorry, that we don’t have better news for you. It is hard to say what really happened here, without getting the full story. It could easily be a hardware fault or an unlucky case when Crate was turned off in a not graceful way (e.g. power loss). The core data layer of CrateDB provides transactional semantics on file level. I would consider a corruption during runtime very very unlikely. If the node would be part of a cluster with replication enabled, such a corruption would most likely self-heal, without users even noticing it. ---

Dear @mahoboy468, your observations indeed indicate that the Lucene data files got corrupted. > It looks like the main directory file, [segments\_N](http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/fileformats.html#Segments%20File) is corrupted. This probably means that a power loss happened while a commit was running. \[1\] Other resources like ["Format version is not supported" - Elasticsearch - Discuss the Elastic Stack](https://discuss.elastic.co/t/format-version-is-not-supported/69027) also indicate that there is no way to ordinarily recover from this situation. In order to recover your data by [carving](https://en.wikipedia.org/wiki/File_carving) them out of the raw data files, you might want to look at the [Apache Luke](https://github.com/DmitryKey/luke) program, as roughly outlined at [The same full-text search engine for different pro... - Atlassian Community](https://community.atlassian.com/t5/Confluence-articles/The-same-full-text-search-engine-for-different-products/ba-p/1319832). You also might want to check out the Lucene CheckIndex program, see [Lucene and Solr's CheckIndex to the Rescue! - DZone](https://dzone.com/articles/lucene-and-solrs-checkindex). Please note that running those programs on your data is completely out of scope for any serious recovery procedure related to CrateDB, I am hereby only sharing some resources with you to indicate how others might have rescued the situation as a last resort. There is no guarantee that this will bring back any of your data. Always take backups! With kind regards, Andreas. * * * 1.
