kiowa2005 Posted December 8, 2021 Share Posted December 8, 2021 (edited) Problem: I am trying to switch my network configuration from bonding mode 4 to backup 1. When I do this in the GUI I lose my network connectivity to the server and I have to reset it back to the following to get it back online. Can anyone tell me why I cannot change the mode to mode 1 (backup1). I thought this should be a safe change to make. Other notes: I have a router based static IP reservation for the eth0 MAC e0:3f:49:a6:12:97 I have all four NICs connected to the router showing activity lights for each Network.cfg (original working version) Quote # Generated settings: IFNAME[0]="br0" BONDNAME[0]="bond0" BONDING_MIIMON[0]="100" BRNAME[0]="br0" BRSTP[0]="no" BRFD[0]="0" BONDING_MODE[0]="4" BONDNICS[0]="eth0 eth1 eth2 eth3" BRNICS[0]="bond0" PROTOCOL[0]="ipv4" USE_DHCP[0]="yes" IPADDR[0]="" NETMASK[0]="255.255.255.0" GATEWAY[0]="192.168.1.1" DNS_SERVER1="192.168.1.1" USE_DHCP6[0]="no" DHCP6_KEEPRESOLV="no" SYSNICS="1" network-rules.cfg (original working version that remains unchanged) Quote # PCI device 0x8086:0x105e (e1000e) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:15:17:d6:8c:6a", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2" # PCI device 0x8086:0x107d (e1000e) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:15:17:95:9b:29", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" # PCI device 0x10ec:0x8168 (r8169) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="e0:3f:49:a6:12:97", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x8086:0x105e (e1000e) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:15:17:d6:8c:6b", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3" network.cfg (new file generated after I change the mode to mode1) Doesn't work at all, no network connectivity Quote # Generated settings: IFNAME[0]="br0" BONDNAME[0]="bond0" BONDING_MIIMON[0]="100" BRNAME[0]="br0" BRSTP[0]="no" BRFD[0]="0" BONDING_MODE[0]="1" BONDNICS[0]="eth0 eth1 eth2 eth3" BRNICS[0]="bond0" PROTOCOL[0]="ipv4" USE_DHCP[0]="yes" DHCP_KEEPRESOLV="no" USE_DHCP6[0]="no" SYSNICS="1" Edited December 8, 2021 by kiowa2005 Quote Link to comment
