<div class="">Hello Maor,<br class="">

Thanks for answering and looking deeper in this case. You’re welcome to connect to my machine since it’s reachable over the internet. I’ll be opening a ticket in moments. Just to feed an update here:<br class="">

I’ve done what you asked, but since I’m running Self Hosted Engine, I lost the connection to HE, here’s the CLI:<br class="">

Hi Vinícius,<br class="">
<br class="">
I was trying to reproduce your scenario and also encountered this<br class="">
issue, so please disregard my last comment, can you please open a bug<br class="">
on that so we can investigate it properly<br class="">
<br class="">
Thanks,<br class="">

For some reason it looks like your networks are both connected to the same IPs.<br class="">
<br class="">
based on the VDSM logs:<br class="">
u'connectionParams':[<br class="">
{<br class="">
u'netIfaceName':u'eno3.11',<br class="">
u'connection':u'192.168.11.14',<br class="">

<br class="">
Can you try to reconnect to the iSCSI storage domain after<br class="">
re-initializing your iscsiadm on your host.<br class="">
<br class="">
1. Move your iSCSI storage domain to maintenance in oVirt by deactivating it<br class="">
<br class="">
2. In your VDSM host, log out from your iscsi open sessions which are<br class="">
related to this storage domain<br class="">
if that is your only iSCSI storage domain log out from all the sessions:<br class="">
"iscsiadm -m session -u"<br class="">
<br class="">
3. Stop the iscsid service:<br class="">
"service iscsid stop"<br class="">
<br class="">
4. Move your network interfaces configured in the iscsiadm to a<br class="">
temporary folder:<br class="">
mv /var/lib/iscsi/ifaces/* /tmp/ifaces<br class="">
<br class="">
5. Start the iscsid service<br class="">
"service iscsid start"<br class="">
<br class="">

<blockquote type="cite" class="">I’m joining the crowd with iSCSI Multipath issues on oVirt here. I’m<br class="">
trying to enable the feature without success too.<br class="">
<br class="">
Here’s what I’ve done, step-by-step.<br class="">
<br class="">
1. Installed oVirt Node 4.1.3 with the following network settings:<br class="">
<br class="">
eno1 and eno2 on a 802.3ad (LACP) Bond, creating a bond0 interface.<br class="">
eno3 with 9216 MTU.<br class="">
eno4 with 9216 MTU.<br class="">
vlan11 on eno3 with 9216 MTU and fixed IP addresses.<br class="">
vlan12 on eno4 with 9216 MTU and fixed IP addresses.<br class="">
<br class="">
eno3 and eno4 are my iSCSI MPIO Interfaces, completelly segregated, on<br class="">
different switches.<br class="">
</blockquote>
<br class="">
<br class="">
This is the point: the OVirt implementation of iSCSI-Bonding assumes that<br class="">
all network interfaces in the bond can connect/reach all targets, including<br class="">
those in the other net(s). The fact that you use separate, isolated networks<br class="">
means that this is not the case in your setup (and not in mine).<br class="">
<br class="">
I am not sure if this is a bug, a design flaw or a feature, but as a result<br class="">
of this OVirt's iSCSI-Bonding does not work for us.<br class="">
<br class="">
Please see my mail from yesterday for a workaround.<br class="">
