Hello,  
Is it possible to turnoff the wsrep\_debug without restarting the node ?  
Actualy here is the configuration

```auto
mysql> SHOW VARIABLES LIKE 'wsrep_debug';
+---------------+--------+
| Variable_name | Value |
+---------------+--------+
| wsrep_debug | CLIENT |
+---------------+--------+
1 row in set (0,00 sec)

mysql>

```

Thanks in advance.

Correct. As This parameter is **dynamic** , you can set it on the fly with the “SET GLOBAL” command without restarting the database.

| Option | Description |
| --- | --- |
| Command Line: | –wsrep-debug |
| Config File: | Yes |
| Scope: | Global |
| Dynamic: | Yes |
| Default Value: | NONE |
