Hi,

My first message on your great board 🙂

I installed discourse on a server with debian 9. Each time I use the command **./launcher** , all is working great but I have this message displayed :

> cupidon@XXXXXXX:/var/discourse# ./launcher rebuild cupidon  
> **stat: cannot read file system information for ‘extfs’: No such file or directory**  
> **./launcher: line 202: /1024** 3 \< 5: syntax error: operand expected (error token is "/1024**3 \< 5")**

Do you know how to fix this ?

Thanks for your help.
