Red Hat Bugzilla – Bug 1001468
The bonding params need to be verified and adjusted if needed to prevent serious network degredations
Last modified: 2015-07-13 01:19:32 EDT
+++ This bug was initially created as a clone of Bug #996120 +++
Description of problem:
It is critical that either the miimon or arp_interval and
arp_ip_target parameters be specified, otherwise serious network
degradation will occur during link failures. Very few devices do not
support at least miimon, so there is really no reason not to use it.
To prevent this case we should check and adjust the arguments if needed during ai and the tui install.
Currently both ways to configure the device don't do any checks on the params and don't even require any params to be set.

IMO (and feel free to argue):
Auto-install: if the user specifies something for the parameters, then don't change anything. If they don't pass any parameters, set some sane default. We generally expect that people know what they're doing with autoinstall
TUI: when creating a new bond, add default options, but allow the user to change/remove. If they're editing, don't suddenly add options that weren't there before.
Need to clone this bug from ovirt-node upstream into downstream to help qe track this issue in rhev-h
The implement solution is:
Provide sane defaults (miimon=100), but let the user override them.
This bug is currently attached to errata RHBA-2013:15277. If this change is not to be documented in the text for this errata please either remove it from the errata, set the requires_doc_text flag to minus (-), or leave a "Doc Text" value of "--no tech note required" if you do not have permission to alter the flag.
Otherwise to aid in the development of relevant and accurate release documentation, please fill out the "Doc Text" field above with these four (4) pieces of information:
* Cause: What actions or circumstances cause this bug to present.
* Consequence: What happens when the bug presents.
* Fix: What was done to fix the bug.
* Result: What now happens when the actions or circumstances above occur. (NB: this is not the same as 'the bug doesn't present anymore')
Once filled out, please set the "Doc Type" field to the appropriate value for the type of change made and submit your edits to the bug.
For further details on the Cause, Consequence, Fix, Result format please refer to:
Thanks in advance.
Previously no default bond options were set, this could lead to network
connection issues. To prevent this some sane defaults are set to "mode=balance-rr miimon=100" if no other options are given at all.
so this bug has been fixed on ovirt-node-3.0.1-9.el6_5.noarch.rpm, change the status into "VERIFIED"
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
