Re: [Users] GlusterFS Distributed Replicate

Hi, in a 2 node cluster you can set the path to localhost:volume. If one host goes down and SPM role switches to the remaining running host, your master domain is still accessible and so your VMs stay up and running.

[Users] too many bouces information message..
by Gianluca Cecchi 08 Jan '14

08 Jan '14

Already received some weeks ago this kind of message I just received today: " Your membership in the mailing list Users has been disabled due to excessive bounces The last bounce received from you was dated 08-Jan-2014. You will not get any more messages from this list until you re-enable your membership. You will receive 3 more reminders like this before your membership in the list is deleted. To re-enable your membership, you can simply respond to this message .. " At the mean time I just re-enabled my membership receiving confirmation message. What could be the reason? I'm only normally using via web my gmail account that I use for other mailing lists too, without any problem.... A difference is that I statistically find more messages from the list that gmails initally puts into spam and that I mark as "not spam".... Any hint here? Thanks, Gianluca

I asked for 3.3.4 target release to be added, but i think folks should consider if to push bugs to 3.3.4, or to 3.4.0 by now.

[Users] Bad volume specification

Under ovirt 3.3.1 I then used a procedure posted here previously where you create a VM, add a disk, then copy over the converted image onto the oVirt created image and away you go. I did this twice under oVirt 3.3.1 and it worked great. Now I have built a new oVirt 3.3.2 system and tried the same thing, and I get the error: VM win7-01 is down.

The original oVirt 3.3.1 system that has now been upgraded to 3.3.2 still boots this same disk image just fine. I'm guessing it's upset because apparentsize and truesize are different? Why did 3.3.1 seem not to care but 3.3.2 does now? Any way I can true these up?

[Users] Need to recreate public RSA key on node
by Bob Doolittle 08 Jan '14

08 Jan '14

Hi, I inadvertently overwrote my root authorized_keys file on my host/node (copied instead of appended :( ), so I need to find the proper public RSA key to put back there for ovirt-engine. But I can't seem to find the private (or public) key on the Engine. There is no actual account "ovirt-engine" on the Engine. Where does this key come from? Any other suggestions on an easy way to recreate the file? This is my only node, and it hosts my Primary Data Domain, so I don't think I can easily remove/re-add it. My node was up at the time, and surprisingly it remains up and operational at least for now. What is the remote root ovirt-engine login used for? -Bob

[Users] Help - Cannot run VM. Invalid time zone for given OS type.
by Dan Ferris 08 Jan '14

08 Jan '14

Hi, Has anyone run across this error: Cannot run VM. Invalid time zone for given OS type. The OS type for these VMs is set to Linux Other. They were all exported from an Ovirt 3.2 cluster and are being reimported into an Ovirt 3.3 cluster. None of these VMs will boot. We also can't delete them because delete protection is enabled and we can't edit the VM to turn off delete protection. Does anyone know what this error means exactly and how to fix it? Thanks, Dan

[Users] Deleting Storage Connection
by Nauman Abbas 08 Jan '14

Hello all I want to delete a storage connection since I'm adding an ISO Domain and it gives me the error "Storage connection already exists.". I'm trying to go for this: http://www.ovirt.org/Features/Manage_Storage_Connections#Delete_connection_… But it just shows me some link and some script. I don't know how use it. A little guidance on it would be great. Sorry for being a noob.
