We needed to update ip addresses on management interface on 3 VM's.
Each of the 3 VM's have 2 interfaces (Management i/f & and an Application i/f.
We also took the opportunity to update from rhel ver 3.10.0-1062.el7.x86_64 to
After updating the network config & doing a stack update, the mac address that was originally associated with eth0, ended up on eth1 and the mac address that was originally on eth1, ended up on eth0.
Also the output of openstack server list, shows the order of the network info has swapped order as well. See below that the 1st 3 vm's(vm01-03 which are in cluster MOD1) which were not part of the update, have 'net-1901' as the 1st network & 'net-1916' as 2nd network, however after the stack update & a poweroff/power on, the vms vm04-06(which are in cluster MOD2), now have 'net-1951' as their second entry & we could not ssh onto the server via the management interface as the rules for the 1951 vlan were associated with the incorrect nic interface.
We were able to access servers vm04-06 after
shutdown -r, after
shutdown -h, followed by a
openstack server start 'server id'the mac addresses got reversed :
| Name | Networks | vm01-az1 | net-1901=10.10.10.65; net-1916=10.10.11.244 | | vm02-az2 | net-1901=10.10.10.66; net-1916=10.10.11.245 | | vm03-az1 | net-1901=10.10.10.67; net-1916=10.10.11.246 | | vm04-az2 | net-196610.10.12.244; net-1951=10.10.10.192 | | vm05-az1 | net-196610.10.12.245; net-1951=10.10.10.193 | | vm06-az2 | net-196610.10.12.246; net-1951=10.10.10.194
