Hello oVirt Community,
This may be my first time writing in. Although, I've been reviewing and pla=
ying with oVirt for the past 3 years. My name is Robert Langley and I work =
for a local Government in Southern California. My agency (with me as the pr=
imary/lead IT person) has been using VMWare vSphere to host our server envi=
ronment for 6 years. I have a few different reasons I want to jump the VMWa=
re ship and I've been pleased with the progression oVirt has been making. I=
do not care to jump from VMWare to Microsoft's Hyper-V, so this had lead m=
e to look into Xen for a while, then dropped anchor with oVirt. I'm determi=
ned to see this implementation through.
I have moved over from the test (workstation class) environment, where I wa=
s really just getting familiar with the commands and UI, and now I am worki=
ng on implementation with server class hardware.
I have the engine up and running. I'll get into more specifics below.
I'm running into an issue where I have not been able to add my Gluster host=
s or add the Storage Domain (I had tried adding the storage domain first).
For my new oVirt and GlusterFS hosts I have the following:
* I want to first mention that I do have a DNS server for the separat=
ed/private networks and those are configured and working properly (forward =
& reverse).
Dell PE R830 and I would like this to be a failover server housed in a sepa=
rate building where we have an Emergency Operations Center and Datacenter (=
server room).
- Has bonded gigabit (2 port) network that is connected to our main n=
etwork & internet, configured to be used for ovirtmgnt. Name =3D gsaov08.en=
t...
o As far as all the various names, oVirt Hosted Engine Deployment com=
plained that the Main network name was seen on more than one interface, or =
something to that effect.
o I did originally have DNS for the separated/private networks config=
ured for forwarding DNS from our main network DNS servers. Which has been r=
emoved and the Hosted Engine Deployment stopped complaining at that point. =
I was going to use the forwarding DNS for another private network I use for=
some management traffic, but that is not as important or an absolute need =
either.
- Has 2nd bonded gigabit (4 port) network (separate/private) for engi=
ne storage. Name =3D gsaov08e.engine.local
- Has 3rd bonded 10G (2 port) network (separate/private) for VM Guest=
storage. Name =3D gsaov08s.stor.local
- Will have a 4th network (separate/private) configured for security =
related devices that are managed by a couple of our VM guests.
As far as storage in this same server.
- I have split up the local storage to be hosted by GlusterFS and thi=
s host is a peer with the other two dedicated GlusterFS storage servers. Th=
at is for the failover piece.
o Engine volume (currently being used for the Hosted Engine) and setu=
p as a replica 3 with the two dedicated GlusterFS storage servers.
o VM Guest "Data" volume. The volume is created, configured and start=
ed. Setup as a replica 3 with the two dedicated GlusterFS storage servers.
So far, this is the only host I have hosting the engine. Now, onto the othe=
r host I am about to run Hosted-Engine -Deploy on.
Dell PE R730 - It has the same network setup as the R830. Storage is a bit =
different. I would like to run another VM Guest GlusterFS volume from here,=
along with 2 other hosts I have. They are currently serving as the vSphere=
ESX hosts and have the same total size of storage to create another replic=
a 3.
The Dedicated GlusterFS Hosts are custom AMD Opteron G2 builds with ASUS se=
rver motherboards. Strictly designed to be dedicated storage servers.
- I'm using the onboard NICs to connect to my management network only=
for the purpose of getting updates. So, internet is served to these hosts =
via a NAT router. Since I figured they don't otherwise need access to our m=
ain network. The primary names =3D gsa-stor1 & gsa-stor2
- They both have a bonded (4 port) gigabit network for the Engine sto=
rage network. Names =3D gsa-stor1e.engine.local & gsa-stor2e.engine.local
- They both have a bonded (2 port) 10G network for the VM Guest stora=
ge network. Names =3D gsa-stor2s.stor.local & gsa-stor2s.stor.local
As far as storage in these servers.
- It is the same as the R830, as these servers are the peers to the R=
830.
First, I added an ISO Storage Domain (NFS). That was successful. Next, I wa=
s trying to add the GlusterFS VM Guest Data Storage Domain. I receive an Op=
eration Canceled: Error while executing action AddGlusterFsStorageDomain: E=
rror creating a storage domain.
When I try to add the Gluster hosts as hosts in the oVirt Manager, I get a =
message stating that SSH has failed, verify that the host is reachable (IP =
address, routable address etc.) You may refer to the engine.log file for fu=
rther details.
I can otherwise communicate with the hosts and the engine.log does not appe=
ar to have specifics to this particular failure. But, there are other clues=
that I don't understand. So, I can follow up with the engine log. It conta=
ins "WARN" entries. They seem to be because I do not have the hosts, for th=
e engine volume, added to the cluster.
Oh, one thing I should mention, I did select the option to enable the Glust=
er service in the default cluster. So, both virt and Gluster are enabled. A=
fter I did so, I wasn't so sure that was a good thing or not. It seems that=
documentation is outdated on whether that is now supported. I noticed from=
screenshots that the selection used to be radio buttons and now they are c=
heck boxes. I did read the release notes for 4.0.1, which seem to talk as t=
hough support for both in a cluster has been added.
Thank you for any help that can be extended.
Robert
