In some cases, it may be necessary to flush and rebuild the TSI index. For example, purging corrupt index files or removing outdated indexed data.

To rebuild your InfluxDB TSI index:

1. Stop the InfluxDB (influxd) process.

   {{% warn %}} Rebuilding the TSI index while the influxd is running could prevent some data from being queryable. {{% /warn %}}

2. Navigate to the data directory in your InfluxDB engine path. The engine path depends on your operating system or custom engine path setting.

   {{< code-tabs-wrapper >}} {{% code-tabs %}} macOS & Linux Windows (PowerShell) {{% /code-tabs %}} {{% code-tab-content %}}

cd ~/.influxdbv2/engine/data/

{{% /code-tab-content %}} {{% code-tab-content %}}

cd -Path 'C:\%USERPROFILE%\.influxdbv2\engine\data\'

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

3. Delete all _series directories in your InfluxDB data directory. By default, _series directories are are stored at /data/<bucket-id>/_series, but check for and remove _series directories throughout the data directory.

   {{< code-tabs-wrapper >}} {{% code-tabs %}} macOS & Linux Windows (PowerShell) {{% /code-tabs %}} {{% code-tab-content %}}

find . -type d -name _series -exec -delete

{{% /code-tab-content %}} {{% code-tab-content %}}

get-childitem -Include _series -Recurse -force | Remove-Item -Force -Recurse

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

4. Delete all index directories. By default, index directories are stored at /data/<bucket-id>/autogen/<shard-id>/index, but check for and remove index directories throughout the data directory.

   {{< code-tabs-wrapper >}} {{% code-tabs %}} macOS & Linux Windows (PowerShell) {{% /code-tabs %}} {{% code-tab-content %}}

find . -type d -name index -exec -delete

{{% /code-tab-content %}} {{% code-tab-content %}}

get-childitem -Include index -Recurse -force | Remove-Item -Force -Recurse

{{% /code-tab-content %}} {{< /code-tabs-wrapper >}}

5. Use the influxd inspect build-tsi command to rebuild the TSI index.

   influxd inspect build-tsi
