[ovirt-users] oVirt node 4.2.x - custom multipath.conf and external storage availability

HI all How can I provide to my oVirt hosts a custom multipath.conf, considering that we are using shared/mirrored FC storage from HPE 3PAR with high availability of provided LUNs, using peer-persistance feature ? To configure correctly this require a custom multipath.conf is required. How I can avoid it will be overwritten during upgrades ? Second topic: Is ALUA feature supported also in oVirt nodes, like for standard RHEL 6/7 and/or CentOS 6/7 ? I was digging for a while into user's digest, but not able to find focused informations. This is the feature needed by peer-persistance, allowing two different volumes to be masked toward a given host with the same WWN and LUN number. Thanks in advance -- Roberto
