Assignee: (unassigned) = eric.desrochers (eric-desrochers-z)
** Changed in: ifenslave-2.6 (Ubuntu Trusty)
Status: Confirmed = In Progress
** Description changed:
+ [SRU justification]
+
+ [Impact]
+
+ Without this patch, trying to add a bond when this one is already
+ defined leads to the following error :
+
+ Example :
+
+ # ifenslave bond0 eth1 eth2
+ sh: echo: I/O error
+ eth1: could not add interface
+
+ [Test Case]
+
+ For info, the ambiguous message only appears when using ifenslave on a
+ bond that is already configured :
+
+ # ifconfig eth1 up
+ # ifconfig eth2 up
+ # ifconfig bond0 up
+ # ifenslave bond0 eth1 eth2 No error on the first execution
+ # ifenslave bond0 eth1 eth2
+ sh: echo: I/O error
+ eth1: could not add interface
+
+ [Regression Potential]
+
+ None expected as the same commit is already in use in the ifenslave
+ package for Wily and in the upstream debian package.
+
+ [Original description of the problem]
+
adding an interface to a bonding interface can result in the error
message sh: echo: I/O error which is highly ambiguous (did the I/O
error occur in sh, echo or is it an I/O error realted to the
command/driver? - at least change this to I/O error occured which is
still not helpful (I/O occured in the kernel driver, please make sure
it supports XY, check with Z would be nice), but at least not
confusing.

my commands
code
sudo modprobe bonding
sudo ifup wlan0
sudo ifup wlan1
sudo ifconfig bond0 # no DHCP example, so I've not idea how to get this
running :( just providing a way to reproduce the error message (which should in
no case be shown with its current content)
sudo ifenslave bond0 wlan0 wlan1
/code
I'm not requesting support here, just to fix the bug which should make
the former unnecessary anyway :)
