Guix is not possible to start swap device/dev/sda2. I noticed this:

# guix system reconfigure /etc/config.scm
...
guix system: error: exception caught while executing 'start' on service 'swap-/dev/sda2':
In procedure swapon: "/dev/sda2": Invalid argument...

# cat /etc/config.scm

I've read manual and I do not know what is wrong:

Swap really did not worked ever in my Guix installation. Let me know what ought to be done?

Just to be sure, could you run "mkswap /dev/sda2"?

Thank you, Julien Lepiller! That exactly was what I need!

Hi,

<znavko <at> tutanota.com> skribis:

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’.
