Hello oVirt guru out there:
I want to seek some advice on upgrade path for our oVirt management vm conf=
iguration. We have been using oVirt for over 3 years. When we first setup=
oVirt environment, Hosted Engine componment did not exist. Our question i=
s should we migrate our current configuration to use Hosted Engine?
First let me give an overview of our configuration. We have blade servers =
in 2 separate racks. D1 & X1. Each side has 10 blades. Storage is iSCSI =
SAN.
Inside our oVirt 3.5.0.1-1.el6 installation, it is configured with 2 data c=
enters. D1 & X1. Each datacenter has the 10 blades for that side. The ma=
nagement function of oVirt (oVirt web console) is running off 2 VMs, ovirt-=
mgmt-1 on D1, and ovirt-mgmt-2 on X1. We have keepalived to maintain a flo=
wing IP for the oVirt management console. The keepalived script makes sure=
only one copy of ovirt-engine is running at any time. It can be on D1 or =
X1. The mgmt VMs have Postgresql setup in replication mode. In case one o=
f the mgmt vm failed, the other mgmt vm on the other rack can pick up the m=
gmt role. Both mgmt VMs can see all blades and SAN resources on D1 & X1.
This configuration has been working well for us. The drawback is if both o=
virt mgmt vm crashed, we will not be able to start them or make any change =
to the ovirt environment. It is because the mgmt VMs are running within th=
e oVirt domain.
We tried to upgrade our configuration to Hosted Engine configuration. From=
what I understand, the Hosted Engine will run in a separate storage domain=
. In both times we tried to upgrade to Hosted Engine, they both failed dur=
ing export and import of current configuration.
I think my questions are:
- will the Hosted Engine model works in our hardware configuration. With h=
ardware in 2 racks, D1 & X1. Can a single Hosted Engine manage hardware on=
both sides?
- How can we achieve redundancy when running Hosted Engine? We need to hav=
e management capibility in case one side completely failed.
Thanks in advance.
Eric
