[ovirt-users] Failing to attaching master domain (nfs shares)

Hi, i've just upgraded to 4.1 after some problem with PKI but now i'm facing problem with master data storage on one datacenter. I've tried to reinitialize data center on new storage domain but same error (http://lists.ovirt.org/pipermail/users/2016-August/075569.html). I really does not understand because all my host see on /rhev/data-center/mnt/... all file of the storage domain. What do i miss? Please help ;) Lionel
