Hi
I get the following error reported on boot with a box that has miltiple
nics bonded using cobbler at provision time.
http://home.ng23.net/boot.jpg
The good thing is though that everything works just fine - So is this
error benign ?
thanks

It's certainly not normal, and could be indicative of some other problem
going on. Setting the max bonds is not critical to make bonding work, but
you should google that error and figure out why it's saying permission
denied, other things could be silently failing.

i hve googled it to death it seems and so far i cant find an answer -
the box is just a vanilla CentOS 5.3 with 4 nics into 2 bonds all done
with cobbler so i dont really see why this would be happening.
will keep looking though

Yeah no luck here either. I didn't think permissions on sysfs were
persistent across reboots, but you could try chmod'ing that directory and
file, and see if you can access it after the system boots up.
Also, one of the few things I found was that the initscripts don't like
when max_bonds is set to 0, so check your modprobe.conf for that.

Actually, i just setup a bond on my centos5.2 system, and I don't even see
that file in that sysfs directory:

Could be a bug in the initscripts?

Well that's weird, you're specifying max_bonds twice but they're different
values. Can you modify your bonding opts and remove the max_bonds option?
I bet that's what's causing those messages.

did you add this or did cobbler?
alias bond0 bonding
alias bond1 bonding
$ more /etc/sysconfig/network-scripts/ifcfg-bond0
# Cobbler generated non-physical interface
DEVICE=bond0
BONDING_OPTS="bonding mode=1 miimon=100 max_bonds=3"
The 'max_bonds=3' isn't needed either for RHEL/CentOS 5.

ok - will remove it and see what happens thanks

Yes, cobbler's post network config script adds it to the modprobe.conf, so
it's redundant to add it to your bonding opts.

that looks better but i still get exactly the same 'error'

Yes, that appears to be in the snippet.
Are we saying that needs to change?

That really only should be done for RHEL/CentOS4. Something like this
*might* fix it (I'm not that familiar with cobbler's code)?

Works just as well for RHEL5 for me, also with multiple bonds. Although
it's not needed anymore for RHEL5, it doesn't seem to break things either.

I realize you may try be to keeping distro-specific switches from being
all over the place, but it's really not needed. Bonding module options
in /etc/modprobe.conf are frowned upon in RHEL5.

The code could check against $os_version if defined and if it contains
rhel, see if it's ">=5", and also not include that in Fedora, as we can
assume any Fedora being deployed with bonding is /very likely/ to be
implemented the same way as RHEL 5 seeing what RHEL 5 is based on
(Fedora 6 or 7, IIRC). It would make the templates somewhat harder to
read, but the users aren't going to need to see it...
Perhaps part of the price of having so much automagic...
