Hello Joop,
thanks for help. I tried now with fresh installation, but i have to
enter a first storage domain to the nfs path i created. So the question
is which path i have to add in engine? Create a new one on host and add
in engine?
thx

What I did was the following (probably missing quite a few steps)
- create (minimum) two folders, one for hosted-engine storage, one for
data storage, iso and export optional
- create exports in /etc/exports
- start nfs server
- make sure permissions are 36:36 on the exports
- start the nfs server
- check if the mounts work (problem areas are: iptables/selinux)
- install ovirt repo
- install hosted-engine
- run 'hosted-engine --deploy'
- I installed from centos-7 iso but appliance should work too, no
experience with it
- enter the correct path when asked for the hosted storage, nfs and
fqdn:/path-to-nfs-he-share
- follow the instruction, not much needs changing from the default
- Networkmanager still seems a problem, use static ip, don't try to
bridge wifi :-)
- If the engine is started using the ha-agent/broker it can take a
while
before the webui is available
- If everything goes OK engine will claim and insert the hosted storage
domain in the database and make it visible in the webui
- DONT use it for VMs
- create a new data domain on fqdn:/nfs/ovirt/data (or whatever your
path is)
- wait until its up
- start creating VMs
My case is a laptop running F22 with hosted-engine on it using a nfs
server provided by my F22 host, engine itself is Centos7.
So all storage is on my host but if I want I can move it somewhere
else,
add storage from somewhere else because I'm nog using local storage
domain. Only thing is the overhead of the network filesystem that being
either NFS/GlusterFS/ISCSI.
There are some guides on how to setup oVirt using hosted-engine but to
be honest its hard to find on the current site and searching on
old.ovirt-.org doesn't work :-(
Let me know how far you get and maybe I can help you further if you get
stuck.

No. I thought you were trying to share from the engine. You
can't
All shares are from the host point of view. Engine is consume the space
offered.

New subject: Where to add NFS Data Storage
Hello All and Joop ;),
ok i think to know what you mean. So my problem is to understand the
construct of hosted engine and the supply of vms. actually i want the
engine as small as possible and the host offer the nfs storage for iso
and data/vms. now i understand that the engine has to be as big as
possible, because the nfs storage is provided by the engine self, right?
that would mean, that if i have 300gb disk on host free i have to give
the engine the max size of lets say 300gb for iso and data/vms, right?
but the question remains, where should i configure the nfs storage since
i must add storage at installation on host. at engine installation i can
say no if i where ask for storage. but i have to add the storage in
webgui, but which one?
as you can see iam a bit confused.

New subject: Where to add NFS Data Storage
Sorry for write again, but its still unclear how to add the nfs storage
and where.
- as far as i understand the engine is in own vm what is neccessary for
ha with 2 ore most host.
- the e.g. nfs storage could be external on own server and will
connected in engine-vm setup
- the host itself needs a storage path at installation process too,
which one? local or external nfs too? what will hosted there? the
engine-vm right?
- so if i only have one host with nfs storage on itself, i have to
create 2 nfs paths, one for the host with engine-vm and one for the
engine-vm for nfs storage right?
- so what is the storage on engine for, all vms?

If you have only one host then:
- have that host export a couple of nfs shares, through /etc/exports
- install hosted-engine rpms on the host
- run hosted-engine-setup, following directions, this will:
-- install the vm in one of the nfs shares
-- installs ovirt-engine INSIDE the vm
-- installs the ovirt-ha-agent and ovirt-ha-broker on your host which
will start the hosted-engine vm
- if the vm is up then you can access its webui and you'll be able to
add an additional storage domain (NFS) which will hold you other VM disks
- make sure dns info is correct, you use static ip addressing, don't use
NetworkManager
