Dvorak David, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest server release of Ubuntu? ISO images are available from http://releases.ubuntu.com/raring/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags removed: aggregation bonding ** Tags added: needs-kernel-logs ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1007371 Title: Precise - bonding without link aggregation Status in “linux” package in Ubuntu: Incomplete Bug description: 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 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1007371/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
