[Users] which file system for shared disk?
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 mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [Users] which file system for shared disk?
Hi Piotr! I've used OCFS2 out of oVirt, so I can't tell you specifically about VM environment, but I suggest you use OCFS2 in place of GFS2. It is simpler to implement, so less components to configure and it care about fencing for you.

Re: [Users] which file system for shared disk?
Hi, gluster is good in scenario when we have many hosts with own storage and we aggregate these pieces it into one shared storage. In this situation data is transferred via Ethernet ore Infiniband. In our scenario we have centralized storage accedes via Fibre Channel. In this situation it would be more efficient when data would be transferred through FC.

Re: [Users] Fedora upgrading from 3.1 to 3.2
Hi Karli 'Restore' certificates basically means taking the backup of /etc/pki/ovirt-engine/certs and /keys and restoring them into 3.2 after installation. --dont-drop-database will do exactly that - leave DB intact; that can be for your benefit in some cases.

I have actually made some headway, I managed to get it passed the database upgrade! As I was looking at the log, I drilled down into the engine-upgrade script at looked at what it was trying to do, which was a pythonic way of doing: # cd /usr/share/ovirt-engine/dbscripts # ./upgrade.sh -s localhost -p 5432 -u engine -d engine Nice progress! So I first reinstalled everything (I´ve stopped counting) and an hour later I was back at just before doing engine-upgrade again. What I did then was to upgrade ovirt-engine-dbscripts first and ran the upgrade.sh script manually (which went by smoothly, output also attached), downgraded all of the ovirt packages back to 3.1.0-4 (because engine-upgrade didn´t think there was any updating to act upon otherwise), then updated ovirt-engine-setup to 3.2.2, lastly ran engine-upgrade. That made it pass the database upgrade, yeay! But! Now it stopped at doing the CA instead... Log is attached. What I find strange is the last line of output from the upgrade.sh: ... Refreshing materialized views... Done. /usr/share/ovirt-engine/dbscripts Where the last lines of upgrade.sh are like: ... run_upgrade_files ret=$? printf Done.\n exit $ret And I looked through run_upgrade_files and couldn´t figure out why that function would exit with /usr/share/ovirt-engine/dbscripts? No that doesn´t quite add up. Something just doesn´t smell right but I haven´t figured it out what it is yet, I think it is the output from another script that runs the upgrade.sh script. There's a pushd/popd action used in sh scripts to change working folder and then get back to the original one. I think that this is what you see here. About the second error, with handling the CA, it seems like it´s having trouble connecting to the database after it´s upgrade, but since the upgrade itself went by OK, I did engine-cleanup, engine-setup, stopped engine, restored the database and started engine again, and it worked. Which should point more to something like a configuration being missed, or improperly handled at the upgrade that makes engine-config fail to connect. Could be; but the fact that reimport of the DB worked is a very good sign. Maybe some old configurations lying around that shouldn´t be, that hinders it, I don´t know. Is there anything handling configuration changes, like rpmconf -a in the upgrade process, after updating the rpms? No, we do not have rpmconf in ovirt. Now, if you have a working engine, that's good. Remember though that you started with clean DB. When DB has entries, the upgrade.sh run may not be as fluent as it was before. But, if it works, I guess you could use the same strategy for upgrading the complete working environment: 1. Backup DB and certificates 2. Upgrade DB in a stand-alone mode and save it aside. 3. Install 3.2, restore the engine DB from upgraded backup. 4. Restore certificates. 5. Start the engine. 6. Enjoy?

[Users] exception occured when adding NFS storage
Hi,
I started to learn the oVirt by following the oVirt Quick Start Guide.
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 into
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 first
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 the
storage:
mkdir -p /mnt/data
chown -R 36:36 /mnt/data
Add the following line to /etc/sysconfig/nfs:
NFS4_SUPPORT=no
Add the following line to /etc/exports:
/nmt/data *(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
systemctl restart nfs-server.service
3. Back to the Default data center, clicked the Guide Me icon to start
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 add
Storage. Internal error, Storage Connection doesn't exist.
From the /var/log/ ovirt-engine/engine.log, I can see:

Re: [Users] exception occured when adding NFS storage
Hi Itamar,
No any trace was logged in the file /var/log/vdsm/vdsm.log during the creation
of the storage on the ovirt.engine side. But the vdsm is running:
# systemctl status vdsmd.service

Hi,
I started to learn the oVirt by following the oVirt Quick Start Guide.
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 into 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 first
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 the
storage:
mkdir -p /mnt/data
chown -R 36:36 /mnt/data
Add the following line to /etc/sysconfig/nfs:
NFS4_SUPPORT=no
Add the following line to /etc/exports:
/nmt/data
*(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
systemctl restart nfs-server.service
3.Back to the Default data center, clicked the Guide Me icon to start
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 add Storage. Internal error, Storage Connection doesn't exist.
From the /var/log/ ovirt-engine/engine.log, I can see:

Please let me know what I was doing wrong.
Thanks,
Hongyi
P.S. If I create the NFS domain in the ovirt.host side (i.e., Export
Path is ovirt.host:/mnt/data), then everything is okay. Not sure why
failed on the ovirt.engine side.

Looks like you had fun there ;) :) Any feedbacks you got so far? Well, I think we have increased the project visibility. Last year (our first participation in FISL) we were a small group in a booth distributing stickers and without any talks at main conference program because they were not approved. This year, besides an improved booth we had a bigger group (around 20 people RedHat + Community) and many keynotes in the main FISL program, including making oVirt work with others open source projects such as Spacewalk and Gluster. Besides the growth mentioned above, it's also important to mention that we heard from some visitors we met last year that oVirt is already running on their companies and at least 2 colleges sharing that they will implement oVirt as solution. For me that's the biggest feedback. -- Cheers Douglas ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
