Hi,
While doing some work to have linux bonding driver be able to work on top
of IPoIB i have run into LOC_QP_OP_ERR with vendor (mellanox PCIX HCA) error 62.
ib0: failed send event (status=2, wrid=52 vend_err 62)
What does this vendor error means? its the same system over which i saw the qp
modify error.
There are some more problematic prints i see here which i will be happy
to get some idea on their meaning...
ib1: dev_queue_xmit failed to requeue packet
ib1: dev_queue_xmit failed to requeue packet
???
ib1: timing out; will leak address handles
ib1: ib_dealloc_pd failed
(the pd dealloc failure is as of the ah leak) but what is the leak cause ???
Below is a more detailed snapshot of the time the problems has occured, I was
playing with this HCA 2 IB links, getting one of down for about 45 seconds (by
some instrumentation of the SM) and then the other, etc.
The ipoib code is unchanged (other then adding the "ipoib_set_mcast_list
called" print).
The bonding code was changed not to set the slave mac address but rather use
the mac address
of the active slave and also override the ether_setup() settings with the
active slave ones.
One thing which i think to see is that the IPoIB attempts to join the IPv4
broadcast group
even when the port IB link is down, am i correct? if yes, would it be easy to
fix this?
Or.
