[ovirt-users] iSCSI storage domain and multipath when adding node

[Gianluca Cecchi]

Hello,
my configuration is what described here:
http://lists.ovirt.org/pipermail/users/2017-March/080992.html

So I'm using iSCSI multipath and not bonding
can anyone reproduce?


Initial situation is only one node configured and active with some VMS

I go and configure a second node; it tries to activate but networks are not
all already mapped and so gies to non operational.
I setup all networks and activate the node

It happens that:
- on the first node where I currently have 2 iSCSI connections and
2multipath lines (with p1p1.100 and p1p2) it is instantiated a new iSCSI
SID using interface "default" and in multipath -l output I see now 3 lines

- on the newly added node I only see 1 iSCSI SID using interface default

My way to solve the situation was to go inside iscsi multipath section
do nothing but save the same config

brutally on first node
iscsiadm -m session -u
--> all iscsi sessions are closed
after a while I see again the original 2 connections recovered, with
correct interface names used

- on second node
iscsiadm -m session -u
--> the only session is cloed
nothing happens
if I set to maintenance the node and then activate the node
--> the 2 correct iscsi sessions are activated...

Thanks
Gianluca
