Well, no, that's the same host. It was discovered at some point back (8
days ago as you can see in the screenshot above). Then it got
rebooted/crashed, PXE-booted again and started sending its discovery
payload again, but gets 422. Usually, if it is the same host, Foreman just
updates existing entry with new facts, or at least, the time of last
report. But in the case above, that did not happen as for some reason
Foreman created another record in a DB (with a different ID) for the same
host. Unless I remove both of the records, 422s will continue to happen. I
was hoping that a gist I provided gives you enough info on what could have
caused that double-record situation for the same host.
Here are my DB entries for the above host:
[root@spc03 ~]# mysql -u foreman -p$DB_PASS foreman -e "SELECT * from hosts
where type = 'Host::Discovered' and NAME = 'mac90e2baea5d58'\G;"
