[~dimitarndimitrov] Maybe, maybe not. The screenshot is useless to me as I can't click on test details.

> However, the thrown exception does not  trigger the failure policy. CASSANDRA-11448 fixed a similar problem. The buggy code is:
> {code}
> protected Directories.DataDirectory getWriteDirectory(long writeSize)
>     {
>         Directories.DataDirectory directory = getDirectories().getWriteableLocation(writeSize);
>         if (directory == null)
>             throw new RuntimeException("Insufficient disk space to write " + writeSize + " bytes");
>         return directory;
>     }
> {code}
> The fixed code is:
> {code}
> protected Directories.DataDirectory getWriteDirectory(long writeSize)
>     {
>         Directories.DataDirectory directory = getDirectories().getWriteableLocation(writeSize);
>         if (directory == null)
>             throw new FSWriteError(new IOException("Insufficient disk space to write " + writeSize + " bytes"), "");
>         return directory;
>     }
> {code}
> The fixed code throws FSWE and triggers the failure policy.
