And what does glusterd log indicate for these failures?
See here in gzip format
It seems that on each host the peer files have been updated with a new entry "hostname2":
[root@ovirt01 ~]# cat /var/lib/glusterd/peers/*
uuid=b89311fe-257f-4e44-8e15-9bff6245d689
state=3
hostname1=ovirt02.localdomain.local

But not the gluster info on the second and third node that have lost the ovirt01/gl01 host brick information...
Eg on ovirt02
[root@ovirt02 peers]# gluster volume info export
