hello
i'm adding a new host into ovirt
after the installation procces is finished I got an error: "VDSM kvm6 command ConnectStoragePoolVDS failed: Cannot find master domain".
on the vdsm server in /dev/disk/by-path/ i see the block device but device-mapper not mappying it
then I found the master's lun in the blacklist: /etc/multipath/conf.d/vdsm_blacklist.conf
