I've confirmed that active-passive bonding is very broken on the latest EL6 kernel, 2.6.32-754.28.1. It works fine on 2.6.32-754.27.1 though.
I've opened up an RHBZ (#1828604), but it's auto-set to private. Copy of the bug is in CentOS #17292 (https://bugs.centos.org/view.php?id=17292) In short, if you use bonding and have EL6 nodes, do not upgrade to .28, and if you are already on .28, downgrade to .27. Howto: # yum install kernel-2.6.32-754.27.1.el6.x86_64 kernel-devel-2.6.32-754.27.1.el6.x86_64 kernel-headers-2.6.32-754.27.1.el6.x86_64 Edit '/boot/grub/grub.conf' (or '/boot/efi/EFI/redhat/grub.conf') and change 'default=X' to the .27.1 kernel entry, reboot. After reboot, remove .28.1; -- Digimer Papers and Projects: https://alteeve.com/w/ "I am, somehow, less interested in the weight and convolutions of Einstein’s brain than in the near certainty that people of equal talent have lived and died in cotton fields and sweatshops." - Stephen Jay Gould _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
