I've managed to get hosted-engine running but could use some direction
for what comes next.
Summary:
4 Hosts, CentOS 7.2, oVirt 3.6 (from ovirt.org <http://ovirt.org>
repo)
All hosts are in default/default datacenter/cluster
All 4 hosts are running glusterd
HE is installed on glusterfs volume, replica 3, on hosts 1,2, and 3. (
started with replica 4, but removed 4th brick to satisfy HE --deploy)
Status:
All hosts are active
Datacenter is not initialized
Issues:
Attach hosted_storage to Default datacenter fails
New volume dialog doesn't allow me to select a datacenter (list is
empty)
Questions:
1. Why doesn't replica 4 work as a glusterfs volume, is this just
because of the installer or is there a more fundamental reason?
3 way replica is the officially supported replica count for VM store use
case. If you wish to work with replica 4, you can update the
supported_replica_count in vdsm.conf
2. I assume the reason I can't create new volumes is because
I don't
have a data storage domain configured yet. I want all of my data
storage to be glusterfs. How do I escape this chicken/egg puzzle?
No chicken and egg here I think. You want a volume to be used as your
master data domain and creating a new volume in a new gluster-cluster
is independent of your datacenter status.
You mentioned your hosts are on default cluster - so make sure your
cluster support gluster service (you should have picked gluster as a
service during engine install)
If you mean, creating new gluster volumes - you need to make sure the
gluster service is enabled on the Default cluster. The cluster that HE
creates, has only virt service enabled by default. Engine should have
been installed in "Both" mode like Roy mentioned.
3. What question should I be asking that I am not?
Thanks
