Hello,
new Discovery Image build (2.9.1) is ready. It is NOT compatible with
Foreman Discovery 4.0.0 from Foreman 1.9 repositories, if you want to
test it, use our nightly builds of Discovery Plugin 4.1.0. If our
testing goes well, this build will become 3.0.0 image release.
If you try to use the new image with 4.0.0, it will report correctly but
Discovery won't be able to reboot it (as the API has changed). Note we
haven't merged support into smart-proxy-discovery plugin, so if your
nodes do communicate via proxy, wait until we merge it later this week.
Until then, use direct Foreman connection.
The new image now does not initialize all network cards with DHCP by
default (use fdi.initnet=all to force this behavior). We have cleaned up
network initialization little bit further, which solved two race
conditions with systemd. Also, initial five fact uploads are not cached
to solve some hardware with late initialization. This can be overriden
with kernel command line options. Also, systemctl is following system
journal on the second console and smart proxy now logs into journald
instead of separate file. Servers with IPMI on port #2 (Dell PowerEdge)
is now reported correctly.
The biggest new feature is text-based interface with enhanced status
information, ability to turn on/off ssh and better reporting/debugging.
The ISO image can now be burned onto CDROM/USB stick and nodes can be
discovered semi-automatically without PXE or DHCP. Possible scenarios:
- fully-automated discovery (traditional approach)
- networks with DHCP but without PXE
- networks without PXE/DHCP
Kernel command line options are accepted to do semi-automatic
provisioning where some of forms can be pre-populated with values. Or
things can be fully automated even on networks without PXE/DHCP by
modifying SYSLINUX configuration on the discovery ISO. This essentially
replaces Foreman Bootdisk plugin in scenarios where generic images
(iPXE) do not work well (hardware compatibility).
Upgrading existing nodes: Deploy the new image onto the TFTP server(s),
upgrade Foreman/Discovery plugin and reboot the existing nodes into the
new image.
