[Bug 1007371] Re: Precise - bonding without link aggregation
To switch - servers (A and B) are connected to same switch and configuration of ports is the same (and server A works fine). To failover test - this weekend I tested failover again. Now when unplug two ports. (In the previous test I unplug only one port). Result is this : - when unplug two ports and run test from only one PC, throughput is 790Mbps (from PC1) or 800 (from PC2). It does not matter which two ports I unplug - when unplug two ports and run test simultaneously from PC1 and from PC2 result is 390Mbps (PC1) and 391 Mbps (PC2) - when unplug only one port and run test simultaneously from PC1 and from PC2 result is 428 Mbps (PC1) and 446 Mbps (PC2). In iptraf on server I see, that for connection to PC1 is working one eth port and when start test on PC2 join to work second eth port. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1007371 Title: Precise - bonding without link aggregation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1007371/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1007371] Re: Precise - bonding without link aggregation
I'm sure that's bug, but I do not know if in kernel or bonding driver. Next - I think, that is it critical bug. For corporate sector is bonding on server (I think) very important and without link aggregation is that server in large network unusable. For example, our network has about 100 PCs (~80 Thin client and ~20 full PC) and throughput in this network is one of the decisive. So - if 12.04 LTS server has bonding without link aggregation - in this case I can't upgrade servers from 10.04 LTS to 12.04 LTS. As I described above, bonding in 10.04 LTS is O.K. - working as failover and as link aggregation. But in Precise bonding is working only as failover. Link agregation NOT WORKING. You can have several gigabit NICs in bonding, but total throughput (bandwidth) to server is only ~1Gbps (for three NICs in Precise is 3x ~305 Mbits/sec, but for three NICs in Lucid is 3x ~925Mbps).

[Bug 1007371] [NEW] Precise - bonding without link aggregation
Public bug reported: I have two servers : server A with Ubuntu 10.04_amd64 and server B with fresh install Ubuntu 12.04_amd64. Server A has 4x Gigabit NIC (all in bond 802.3ad) and server B has 3x Gigabit NIC (all in bond 802.3ad). As switch is 802.3ad capable Cisco. Throughput to server A is OK - from one PC with Gigabit NIC is ~925 Mbits/sec, from two PCs (tested simultaneously) is still 2x ~925 Mbits/sec. Ethernet Channel Bonding Driver is v3.5.0 (November 4, 2008). But throughput to server B (with the same NIC interfaces configuration as server A) is without link aggregation - from one PC with Gigabit NIC is ~925 Mbits/sec, from two PCs is 2x ~460 Mbits/sec, from three PCs is 3x ~305 Mbits/sec etc. With iptraf I see, that all port is working, but without link aggregation. -- Server B - interfaces -- # The loopback network interface auto lo iface lo inet loopback # Trunk all eth auto eth0 iface eth0 inet manual bond-master bond0 auto eth1 iface eth1 inet manual bond-master bond0 auto eth2 iface eth2 inet manual bond-master bond0 auto bond0 iface bond0 inet static address 10.100.6.1 netmask 255.255.254.0 network 10.100.6.0 broadcast 10.100.7.255 gateway 10.100.7.1 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 192.168.1.1 dns-search domain.com # setting bond bond-slaves none bond-mode 4 bond-miimon 100 # only for 802.3ad bond-lacp-rate 1 - cat /proc/net/bonding/bond0 - Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: fast Min links: 0 Aggregator selection policy (ad_select): stable Active Aggregator Info: Aggregator ID: 1 Number of ports: 3 Actor Key: 17 Partner Key: 1001 Partner Mac Address: 58:8d:09:2f:ca:c8 Slave Interface: eth2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:15:17:28:e9:a6 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth0 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:1b:21:1b:44:09 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth1 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 00:1b:21:2b:49:18 Aggregator ID: 1 Slave queue ID: 0 ** Affects: ubuntu Importance: Undecided Status: New ** Tags: aggregation bonding precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1007371 Title: Precise - bonding without link aggregation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1007371/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
