Public bug reported: Problem description
In the MAAS + iBFT + iSCSI boot scenario, iscsistart -f returns iface.bootproto = STATIC. In the current link, the netplan conversion of initramfs fails to generate a static address correctly for PROTO=static, resulting in /run/netplan/<iface>.yaml containing only nameserver and lacking addresses. Consequently, cloud-init cannot obtain the MAAS datasource. Reproducer 1, Set up a common maas env (For me ,it's a libvirt + maas env) 2, Prepare a iscsi disk 3, Configure libvirt to boot from iBFT sudo virt-xml n1 --edit --boot kernel=/usr/lib/ipxe/ipxe.lkrn,kernel_args="dhcp && chain http://172.16.0.1:8080/config-boot-ibft-maas.ipxe"; 4, Create config-boot-ibft-maas.ipxe, and run 'python3 -m http.server 8080' to enable it to be accessed via HTTP - https://paste.ubuntu.com/p/TYTcPRjrCD/ 5, Enable iscsi_auto from MAAS GUI: iscsi_auto break=init 6, Now /run/netplan/<iface>.yaml contains only nameserver and lacks addresses - https://paste.ubuntu.com/p/TCZr2tpFC7/ Proposed solution In the parsing of iBFT iface.bootproto: 1, DHCP is mapped to PROTO=dhcp, IPV4PROTO=dhcp. 2, STATIC is mapped to PROTO=none, IPV4PROTO=static 3, Other values remain transparently transmitted. This satisfies both: 1, The netplan conversion can correctly generate static addresses. 2, Consumers of dynamic-interfaces can still retain static semantics through IPV4PROTO. ** Affects: open-iscsi (Ubuntu) Importance: Undecided Status: New ** Tags: sts ** Tags added: sts -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2147499 Title: open-iscsi initramfs: preserve static iBFT semantics while fixing netplan rendering for MAAS boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/open-iscsi/+bug/2147499/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
