Hello dears,
i've got some troubles with reattaching gluster volumes with data.
1) Base on a lot of tests I decided clear oVirt database ( #
engine-cleanup ; # yum remove ovirt-engine; # yum -y install
ovirt-engine; # engine-setup)
2) clearing sucessfully done and start with empty oVirt envir.
3) then I added networks, nodes and make basic network adjustment = all
works fine
4) time to attach volumes/ domains with original data ( a lot of
virtuals , ISO files , .... )
So, main question is about HOWTO attach this volumes if I haven't
defined any domain and can't clearly import them ??
Current status of nodes are without glusterfs NFS mounted, but bricks are OK
