Hi Baptiste, usually a SAN doesn't support bonding (see post of Nicolas) of its interfaces, so you have to use multipathing technology.
You have to separate all nics in different subnets so multipath can work. Command multipath -ll with show the connected paths. If you "merge" all paths in one subnet you will have the result/behavior you just posted. So this is less oVirt related, more network specific. We have a running iSCSI config with 4 networks and oVirt runs well. Maybe the following link will help you here: https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Linux/6/pdf/DM_Multipath/Red_Hat_Enterprise_Linux-6-DM_Multipath-en-US.pdf Cheers, Sven. -----Ursprüngliche Nachricht----- Von: users-boun...@ovirt.org [mailto:users-boun...@ovirt.org] Im Auftrag von Nicolas Ecarnot Gesendet: Donnerstag, 21.

I don't know if this is the best setup, but this is exaclty what I did (iSCSI with an Equllogic SAN) : I bonded 4 interfaces of the iSCSI subnet, and it's working fine so far... -- Nicolas Ecarnot _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
