Re: [ovirt-users] Is it possible to add ISCSI over iser?
Arman,
One of my storage domains is iSCSI using iSER. You need the following
in vdsm.conf:
[irs]
iscsi_default_ifaces = iser,default
I believe the proper way to set that so it's preserved during node
updates is the following
# cat /etc/ovirt-host-deploy.conf.d/40-custom-vdsm-config.conf
[environment:enforce]
VDSM_CONFIG/irs/iscsi_default_ifaces=str:iser,default
The filename I believe can be changed, just requires .conf extension
Once VDSM is configured to use iser you can add the domain in the GUI
using the IPoIB IP address to initiate iSER.
ovirtnode01 # iscsiadm -m session
iser: [3] 192.168.211.245:3260,1 iqn.2014-04.DOMAIN.vmstore1:ovirt-data_iscsi

Hi,
I am trying to attach my new storage domain over iser.
My server always gets that request is tcp/ip not rdma.
Simple work around is login from hosts over iser.
Would be good to add a possibility to select the protocol of
iscsi:tcp/iser/srp.
Thanks,
Arman
PS
for those who was struggling with same trouble:
1) on hosts:
add lines in /etc/rdma/rdma.conf
# Load iSER module
ISER_LOAD=YES
2) service rdma restart (or modprobe ib_iser
3) iscsiadm -m discovery -t st -p 10.10.10.31 -I iser
4) iscsiadm -m node --login
5) check if disks are there
iscsiadm -m session -o show
