Hello,
Two hosts, setup the same as far as I can see, behave differently when
trying to offload builds, any idea how I can get more information on
what the #<unspecified> might indicate? Looking at
guix/scripts/offload.scm:551 suggests the result is not a string.
$ guix offload test
guix offload: testing 2 build machines defined in '/etc/guix/machines.scm'...
guix offload: 'host1.mydomain.co.uk' is running guile (GNU Guile) 2.0.13
guix offload: 'host2.mydomain.co.uk' is running guile (GNU Guile) 2.0.13
guix offload: Guix is usable on 'host1.mydomain.co.uk' (test returned "/gnu/store/883yjkl46dxw9mzykykmbs0yzwyxm17z-test")
guix offload: error: failed to use Guix module on 'host2.mydomain.co.uk'
(test returned #<unspecified>)
/etc/guix/machines.scm:
(list
(build-machine
(name "host1.mydomain.co.uk")
(system "x86_64-linux")
(host-key "ssh-ed25519 AAAAC3longkeyhere/wm root@host1")
(user "myles")
(private-key
(string-append (getenv "HOME") "/.ssh/id_rsa")))
(build-machine
(name "host2.mydomain.co.uk")
(system "x86_64-linux")
(host-key "ssh-ed25519 AAAAC3notherlongkeyhere root@host2")
(user "myles")
(private-key
(string-append (getenv "HOME") "/.ssh/id_rsa"))))
When trying this:
$ ssh host1.mydomain.co.uk guile -c "'(use-modules (guix config))'"
$ ssh host1.mydomain.co.uk guile -c "'(use-modules (guix config))'"
both succeed, i.e. return nothing.
Thanks,
Myles

What you see here most likely means that host2 threw an exception while
executing this code:
http://git.savannah.gnu.org/cgit/guix.git/tree/guix/scripts/offload.scm#n543
The reason could be:
1. That the (guix …) modules could not be found in the search path
(your tests suggest this is not the case);
2. That an exception was thrown, for instance because the ‘with-store’
form failed to connect to the daemon on that machine (is the daemon
running on that machine? Is it listening on
/var/guix/daemon-socket/socket and not some other place?).
We should definitely improve that and provide details about the
exception, at least.
HTH!
Ludo’.

Yes, that was probably the problem. I have since updated the host
systems, rebooted, restarted the daemons and now it works, thanks.

Yes, I agree, because 'guix offload test' should provide useful details
when it fails and not just when it succeeds.
