Re: [ovirt-users] Where to add NFS Data Storage
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 Am 2016-03-20 14:34, schrieb Joop: > On 20-3-2016 11:49, Taste-Of-IT wrote: >> Hello Joop, >> >> actually right after the installation i have no storage domain. so >> what have i to do in detail? my installation path at installation are >> /var/ovirt/exports/data and /var/ovirt/exports/iso. the data i added >> at installation for the host. at engine installation i say no to >> storage domain. as far as i see and understand i have no storage >> domain in cluster, also for default and those i added in installation >> process of host. >> >> so what have i todo in detail? > 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.

Create a new one on host and add in engine? 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.

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.

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?

- 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 Joop
