S01034

## Error Message {#error_message .section}

`MergeRunner::checkAndDoMerge: Chunk <xxx> does not exist in TSDB compaction. RefId: S01034`

## Probable Causes {#probable_causes .section}

This error occurs when the TSDB engine checks if the level files of a chunk need to be compacted but the chunk does not exist, because the involved table, chunk, or database may have been deleted.

## Solutions {#solutions .section}

Use the [getChunksMeta](../../Functions/g/getChunksMeta.md) function to check if the specified chunk exists on the local data node. If it no longer exists, the error can be ignored.
