`makedhcp -q <node>` on Ubuntu's ISC-limited releases answers "no DHCP reservation found" when it cannot read dhcpd.conf. The operator reads that as a node without a reservation. An InfiniBand node also gets an answer with no hardware address. _query_isc_static_host in dhcp.pm read the file with an -r test and dropped a failed open. It also matched only a "hardware ethernet" line, while _add_isc_static_host writes "hardware infiniband" for an InfiniBand node and adds a twin declaration between the same markers. _read_isc_conf_lines now returns the read error, _query_isc_static_host returns it to listnode, and listnode answers the caller with an error. The parser accepts any hardware type and keeps the first declaration of the block. The path of dhcpd.conf and the distribution name are package variables, so a test can drive the query and listnode. dhcp_isc_static_host_query.t covers the InfiniBand address, the twin declaration, the unreadable file and the listnode answer. It fails without this change. Signed-off-by: Daniel Hilst <392820+dhilst@users.noreply.github.com>
xCAT
xCAT is a toolkit for deployment and administration of clusters of all sizes.
The xCAT sunset was only a quick eclipse
Dear xCAT Community,
The xCAT sunset has changed course. VersatusHPC has been invited to join the xCAT Consortium, and future development will move toward direct upstream contributions coordinated with the Consortium and its existing member companies.
That matters most for Enterprise Linux 10 (EL10). EL10 support is coming to xCAT, restoring a future operating-system path for sites that still rely on xCAT. This is an important change from the previous sunset guidance, where the lack of an EL10 path was one of the strongest reasons to move away from xCAT.
The xCAT Consortium continues to recommend Confluent as the long-term successor to xCAT, and that remains the Consortium position. Users planning new cluster-management deployments should evaluate Confluent and its xCAT comparison documentation.
At the same time, xCAT is no longer sunsetted. The Consortium and participating companies will continue updating xCAT while there is community and user demand for it.
In summary:
- xCAT development is continuing upstream through the Consortium and participating companies.
- Enterprise Linux 10 support is coming.
- Confluent remains the Consortium-recommended successor and migration path.
- xCAT updates will continue while there is community and user demand.
We want to thank the xCAT Consortium and community for keeping this project moving. The sun went behind the moon for a moment, but xCAT is still here.
For more information on Confluent and how to get started, please visit the Confluent: Project Page, Documentation or Confluent vs xCAT comparison.
With thanks,
The xCAT Consortium
