Hello,
I'm fairly new to multipath and I am having an issue with it not using
all of my NICs. Currently, my node has 4 gigE NICs to my storage network
and the SAN has 8 gigE NICs to the same network and I am attempting to
setup multipath with ISCSI in order to utilize more than 1 gigabit
connection. However, when I use nload to check the network usage, you
can see the traffic hop around the NICs. For example, data would send
for 2-3 seconds on eth1, then stops and starts on eth2, then stops and
starts back up on eth3. All perfectly distributed, but in this setup,
unable to reach beyond the capacity of a 1 gigabit connection.
I have each NIC on a different network (e.g. 10.1.1.0/24 for eth1,
10.1.2.0/24 for eth2, etc.). Netstat shows that the connections are
being made each to different IPs:

(10.1.*.8 is the node and 10.1.*.241 is the SAN)
Here is my /etc/multipath.conf:
defaults {
path_grouping_policy multibus
path_selector readsector0
polling_interval 3
path_selector "round-robin 0"
failback immediate
features "0"
no_path_retry 1
rr_weight uniform
rr_min_io 100
# user_friendly_names yes
}
Both servers are running Ubuntu 12.04LTS.
Any ideas?
Thanks,
Eric

I tried "service-time 0", but it didn't seem to change. I ran "multipath
-ll" and it still shows policy="round-robin 0". I restarted the
multipath service, but no luck.
Here's my current config after some suggested changes from the
#device-mapper channel on freenode:
defaults {
path_grouping_policy multibus
path_selector readsector0
polling_interval 3
path_selector "service-time 0"
failback immediate
features "0"
no_path_retry 1
rr_weight uniform
rr_min_io_rq 1
# user_friendly_names yes
}

Hannes,
Here's the output of "route -n":
0.0.0.0 209.124.44.1 0.0.0.0 UG 100 0 0 br0
10.1.1.0 0.0.0.0 255.255.255.0 U 0 0 0 br1
10.1.3.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
10.1.4.0 0.0.0.0 255.255.255.0 U 0 0 0 eth3
10.1.5.0 0.0.0.0 255.255.255.0 U 0 0 0 eth4
10.1.6.0 0.0.0.0 255.255.255.0 U 0 0 0 eth5
10.2.5.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr2
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0
209.124.44.0 0.0.0.0 255.255.255.0 U 0 0 0 br0
br0 is a bridge to eth0 and br1 is a bridge to eth1. eth1-5 are on the
network with the SAN.

Eric

Probably a routing issue. What is the routing table?

Have you tried changing this to queue-length or service-time?

* Multipath not using multiple NICs at once

Hello,
I'm fairly new to multipath and I am having an issue with it not using
all of my NICs. Currently, my node has 4 gigE NICs to my storage network
and the SAN has 8 gigE NICs to the same network and I am attempting to
setup multipath with ISCSI in order to utilize more than 1 gigabit
connection. However, when I use nload to check the network usage, you
can see the traffic hop around the NICs. For example, data would send
for 2-3 seconds on eth1, then stops and starts on eth2, then stops and
starts back up on eth3. All perfectly distributed, but in this setup,
unable to reach beyond the capacity of a 1 gigabit connection.
I have each NIC on a different network (e.g. 10.1.1.0/24 for eth1,
10.1.2.0/24 for eth2, etc.). Netstat shows that the connections are
being made each to different IPs:

(10.1.*.8 is the node and 10.1.*.241 is the SAN)
Here is my /etc/multipath.conf:
defaults {
path_grouping_policy multibus
path_selector readsector0
polling_interval 3
path_selector "round-robin 0"
failback immediate
features "0"
no_path_retry 1
rr_weight uniform
rr_min_io 100
# user_friendly_names yes
}
Both servers are running Ubuntu 12.04LTS.
Any ideas?
Thanks,
Eric
