Hi,

According to swapon(2), there are 3 conditions that can lead to this
error:

       EINVAL The file path exists, but refers neither to a regular  file  nor  
to  a
              block device;

       EINVAL (swapon())  The  indicated path does not contain a valid swap 
signature
              or resides on an in-memory filesystem such as tmpfs(5).

       EINVAL (since Linux 3.4)
              (swapon()) An invalid flag value was specified in flags.

Did you run “mkswap /dev/sda2” beforehand?

Thanks,
Ludo’.
