I used one server as the ovirt.engine, and another server as the ovirt.host= . Both servers run Fedora 18. After executing the command "engine-setup" in the ovirt.engine, I can get i= nto the admin portal to start the configuration of host, storage, etc. Here= was what I am doing: 1. In the Default data center, I clicked the Guide Me icon. The firs= t thing is to configure the host. After waiting for 4-5 minutes, I saw the = host ovirt.host is displayed under the Host tab with the Up status. 2. On the ovirt.engine server, I did the following before creating th= e storage: mkdir -p /mnt/data chown -R 36:36 /mnt/data Add the following line to /etc/sysconfig/nfs: NFS4_SUPPORT=3D"no" Add the following line to /etc/exports: /nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=3D36,anongid=3D= 36) systemctl restart nfs-server.service 3. Back to the Default data center, clicked the Guide Me icon to star= t the configuration of new storage. 4. On the New Storage dialog, set Name field to be NFS-Share, and set= the Export Path field to be ovirt.engine:/mnt/data. Then click OK After couple of minutes, I saw the error window popped up: Error: Cannot ad= d Storage. Internal error, Storage Connection doesn't exist. >From the /var/log/ ovirt-engine/engine.log, I can see: 2013-07-10 11:37:51,300 INFO [org.ovirt.engine.core.vdsbroker.vdsbroker.Co= nnectStorageServerVDSCommand] (ajp--127.0.0.1-8702-1) [41c282da] FINISH, Co= nnectStorageServerVDSCommand, return: {00000000-0000-0000-0000-000000000000= =3D100}, log id: 1bca7819 2013-07-10 11:37:51,303 ERROR [org.ovirt.engine.core.bll.storage.NFSStorage= Helper] (ajp--127.0.0.1-8702-1) [41c282da] The connection with details 128.= 224.147.229:/mnt/data failed because of error code 100 and error message is= : generalexception 2013-07-10 11:37:51,382 WARN [org.ovirt.engine.core.bll.storage.AddNFSStor= ageDomainCommand] (ajp--127.0.0.1-8702-6) [2612bf14] CanDoAction of action = AddNFSStorageDomain failed.

[Users] which file system for shared disk?
by Piotr Szubiakowski 11 Jul '13

11 Jul '13

Hi, we are developing an application where would be great if multiple host could have access to the same disk. I think that we can use features like shared disk or direct LUN to attach the same storage to multiple VM's. However to provide concurrent access to the resource, there should be a cluster file system used. The most popular open source cluster file systems are GFS2 and OCFS2. So my questions are: 1) Does anyone have share disk between VM's in oVirt? What fs did You used? 2) Is it possible to use GFS2 on VM's that are running on oVirt? Does anyone have run fencing mechanism with ovirt/libvirt? Many thanks, Piotr

[Users] [URGENT] VMs not starting
by Juan Pablo Lorier 09 Jul '13

09 Jul '13

Hi, I've tried with a brand new fedora vm without OS and I have the same error. I've made the configuration change proposed by Joop not only for 3.2 version but also for 3.1 just in case something stays in the vms after creation (as they were not exported and then imported, just used the LUN). I hope someone can give me a hand in this. Regards,

[Users] RAID1 mirror on ovirt-node + engine nfs server
by Jason Keltz 09 Jul '13

09 Jul '13

Hi. I've been reading about ovirt, and ready to try my own experiments with it. I have two small questions.. When an ovirt-node is installed from the standard ISO, there's no mention in the documentation about setting up a RAID1 mirror for the root disk on the node. I'm sure that once I get around to working out kickstarting the node, I could easily install the raid1 mirror, but I'm just wondering why I don't see that in the default ISO. Maybe I'm just missing something. Is redundancy of the disk on the node not important? Sure, if the node goes down, I guess the VMs could be run on other nodes, but if we can prevent the node from going down in the first place, then why not? I also have a question about the storage backend. In particular, I have a pretty powerful server that I intend to use as the NFS server, and a few servers to use as nodes. On the other hand, I don't have a powerful machine (at the moment) to use for the ovirt-engine. Would it be poor practice to run the ovirt-engine ON the NFS server? During engine setup, I see that you can setup an NFS share for ISOs from the ovirt-engine, but I don't think there's mention of just generalized storage there. I suspect it's "poor practice", but I thought I'd ask anyway. My setup will be relatively small (say, 4 nodes), and this would let me reduce 1 general server from the infrastructure (dedicated ovirt-engine). Thanks! :) Jason. ps: At the moment, I am not subscribed to users - please cc: me on responses.
