This page documents an earlier version of InfluxDB OSS.[InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a
copy of the database file doesn’t expose usable tokens. Existing
tokens are hashed on first startup and the original strings can’t
be recovered afterward — **capture any plaintext tokens you still
need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

The `influxd inspect verify-wal` command analyzes the Write-Ahead Log (WAL)
to check if there are any corrupt files.
If it finds corrupt files, the command returns the names of those files.
It also returns the total number of entries in each scanned WAL file.

## Usage

```sh
influxd inspect verify-wal [flags]
```

## Output details

`influxd inspect verify-wal` outputs the following for each file:

* The file name.
* The first position of any identified corruption or “clean” if no corruption is found.

After the verification is complete, it returns a summary with:

* The number of WAL files scanned.
* The number of WAL entries scanned.
* A list of files found to be corrupt.
