Can you tell me which kernel worked previously? There have been some changes to bonding code upstream recently (in the last two weeks), but I'm not sure that is the problem. There is also this tunable: /proc/sys/fs/file-max which may have some effect. What does that output look like on your currently-running system? On an upstream kernel based on 2.6.30, mine shows: # cat /proc/sys/fs/file-max 100216 and on a f10 system running 2.6.27, mine shows: # cat /proc/sys/fs/file-max 733944 Previous working kernel was kernel-2.6.29.4-167.fc11.x86_64 # cat /proc/sys/fs/file-max 300478 One other thing I forgot is the error above is with ifenslave -v without the -v option it simply says Enslave failed anything else you need just let me know Do you get the same error if you try to add the slave to the bond by doing this: echo +eth0 > /sys/class/net/bond0/bonding/slaves Yep same error # echo +eth1 > /sys/class/net/bond0/bonding/slaves -bash: echo: write error: Too many open files in system This sounds more like a kernel problem than something specific to ifenslave. Can you open any files (like what about just creating a new file in /tmp)? Yes everything seems to be working fine apart from that - I can create files. Don't see anything strange in messages etc. Can ifconfig up and down both wired and wireless nic's and have either one working. That's how I'm doing this just ifconfig and iwconfiged the wireless card up (not near the lan cable at the moment) and I'm away. Apart from not being able to create a bond device out of them now I've not noticed any other problems at all. Can you enslave eth0 without problems? Can you also try this: # echo 800000 > /proc/sys/fs/file-max and see if you can then enslave eth1. Of course there has been no change to the BCM4312 driver in fedora between those builds. Have you been using the fedora driver or are you using one from broadcom or some other source? I can enslave eth0 no problem tried enslaving eth1 after doing echo 800000 > /proc/sys/fs/file-max no change - still the same error I am using the broadcom and kmod-wl from rpmfusion # yum list installed | grep wl akmod-wl.x86_64 5.10.91.9-3.fc11 @rpmfusion-nonfree-updates broadcom-wl.noarch 5.10.91.9-1.fc11 @rpmfusion-nonfree-updates iwl3945-firmware.noarch 15.32.2.9-1.fc11 installed iwl4965-firmware.noarch 228.57.2.23-5.fc11 installed iwl5000-firmware.noarch 8.24.2.12-1.fc11 installed kmod-wl.x86_64 5.10.91.9-3.fc11.1 @rpmfusion-nonfree-updates kmod-wl-2.6.29.3-155.fc11.x86_64.x86_64 5.10.79.10-2.fc11.6 installed kmod-wl-2.6.29.4-167.fc11.x86_64.x86_64 5.10.91.9-3.fc11 @rpmfusion-nonfree-updates kmod-wl-2.6.29.5-191.fc11.x86_64.x86_64 5.10.91.9-3.fc11.1 @rpmfusion-nonfree-updates Looks like this bug is down to the broadcom driver. I just grabbed the latest b43 driver from linux wireless which now supports my device:- 0b:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11b/g [14e4:4315] (rev 01) and now ifenslave works perfectly and I once again have a fully functional bond0 Sounds great! I'll close this out, then. |
