Use NFS on each host to export the local disk to your cluster. Ensure this is remembered, as when you want to reboot a specific node, you have to put the storage into maintenance as well. I also like to pin each VM using the storage to the node the NFS export lives on. --julian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

We have an open RFE for that, unfortunately it's still not ready. Thanks. My reason for looking into this is I need to reboot my prod SAN switch.

Re: [ovirt-users] Educational use case question
Hey Michael, > I am teaching IT subjects in TAFE (a kind of post-secondary technical > college) in Australia. Great news for this tech to be in tafe. I remember my time at Logan tafe got me into linux. We are currently looking for a virtualisation platform that will allow students to install and manage VMs via web interface. VMware is being proposed but I am trying to get KVM and the RedHat ecosystem in the lab as much as possible. I have reasonable experience with running virt manager on CentOS 7, but oVirt is new. I have it installed and running OK but am not sure how to proceed with configuration. I basically want to run a single physical server which will be the KVM host, the ISO and data store, and the home of oVirt engine ... in other words a complete oVirt-managed KVM virtualisation platform running on one physical machine (32GB RAM). It will only ever need to run a handful of VMs with little or no real data or load. Is this possible/feasible? If possible/feasible, where should oVirt engine go ... on the host itself, or into a VM guest? If it was me, I would do the engine install on the metal host itself. Will be a lot easier for you, as long as you _know_ you will not be adding more metal nodes to the oVirt setup. I would also be looking into the "VM Pool" feature for your student. This will give you a pool of VMs which after use can be reset to a default configuration. The web interface is what is making oVirt an attractive option at this stage, as students will be working from Windows clients on a corporate network. Do VM GUI display well in the browser? I have no experience using oVirt from Windows, but if there is a splice client available I see no reason why it shouldn't work. If you're local to QLD, I am more then happy to help in person. --julian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

That's the thing. Ovirt actually creates that dir when I go and try to
add the storage. It mounts the LVM device to that dir then fails. In the
logs I posted at http://pastebin.com/fzN9ktAX you can see it is failing
with a permission denied error. The command that is above the error is
touch. I think it is trying to touch a file to ensure all is well and
when that fails it gives the error.
If I knew where in the code to prefix the touch command with sudo and
add a line to the sudoers entry I can test this idea.

Please state the all the chown you tried. Possibly a starting point for automating LVM device permissions setting is https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Logical_Volume_Manager_Administration/udev_device_manager.html and in particular the possibility to add, under /lib/udev/rules, a customized file based on the one found in /usr/share/doc/device-mapper/12-dm-permissions.rules Not tried myself though... I don't think permissions for the device are the root cause of the issue. The way I see it behave when I try and mount it is: vdsm will mount the device(If I'm quick I can see this with a LS). It then tries to write some kind of test file(I'm guessing) and as the mount point is still owned by root when vdsm tries to do the touch to test it fails. Then vdsm backs out and I get the failed to add storage error. --julian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

It's a local LVM mount. If the lv is shared, you cannot create a file system and mount it on multiple hosts (unless you are using cluster file system). If this local storage for one host, you should create a file system and mount it, and then you can use the mountpoint as local storage. If I proceed this way then the ovirt node needs to be in it's own local cluster, correct? Please describe in details what are you trying to do and how did you create the storage domain in the engine side. I first did a default centos install which created the LVM stuff. I then lvrename the home LV to images LV. My end goal is to use the posix compliant mount option to have each of my ovirt nodes the option to use local storage for VMs for which I'm not fussed if they can migrate between the cluster or not. Does this make more sense? --julian ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

But I still don't understand what it's trying to do. Just to recap, I do
see it create the dir and mount the device. But when it fails it umounts
everything.
I tried to manually create the DIR it is expecting, but ovirt seems to
remove it and re-create it which then ends up with root:root. I can see
this as when I add the storage I run watch ls -lh and can see it all occur.
Any help would still be greatly appreciated!

That's the thing. Ovirt actually creates that dir when I go and try to
add the storage. It mounts the LVM device to that dir then fails. In the
logs I posted at http://pastebin.com/fzN9ktAX you can see it is failing
with a permission denied error. The command that is above the error is
touch. I think it is trying to touch a file to ensure all is well and
when that fails it gives the error.
If I knew where in the code to prefix the touch command with sudo and
add a line to the sudoers entry I can test this idea.

This could explain why the touch command fails.
