Key Issues Resolved
Issue #4629 For sites that would like to forward to their own DNS servers, the site table includes the 'forwarders' attribute to allow for this. If the site internal DNS resolves RFC1918 addresses, xCAT dns doesn't work.
Issue #5035 NODE info missing from /opt/xcat/xcatinfo
after diskless and statelite boot
Issue #5073 Provide an example in postinstall to show how to patch initrd for diskless
Issue #4996 "xcatd: SSL listener" process keeps 100% cpu and all xCAT requests hang
Issue #4961 Switching to goconvers doesn't modify conserver startup configuration. goconserver doesn't start on reboot
Issue #4959 chroot, rpm -qa error: Failed to initialize NSS library
Issue #4951 goconserver doesn't work in hierarchical mode
Issue #4947 In large systems, "xcatmax*" default configuration values are not sufficient
Issue #4933 There is httpd exception in diskless service node which is running rhels7.5-snap2
Issue #4929 xcatd failed to start in rhels7.5-snap2 diskless service node
Issue #4865 kdump testing on diskless RHEL 7.4 ppc64le (Pegas 1.0) intermittently takes up to 5-6 mins to update nfs path in /etc/kdump.conf
Issue #4009 Commad makeconservercf should check attribute cons in node definition
Restrictions and Known Issues
Issue #5121 rspconfig failed to set bmc ip etc in some specific condition
Issue #3513 For the latest xCAT-genesis-base, the mlx4_en driver 2.2-1 (Feb 2014) is included, it can not support Mellanox Ethernet NIC that need driver newer than 2.2-1, for more information, please reference build genesis locally with latest RH MN
Issue #5057 This issue cannot be reproduced, and the work around is : check the bmc state use rflash <node> -l
, if the target firmware state is Active(+)
, execute rpower <node> boot
to reboot the host and let new firmware take effect.
Issue #3284 While selinux on KVM host was reconfigured from enforcing
to disabled
, rpower failed to power previous created KVM guest on
