[Users] Export not exporting the disk
by Juan Pablo Lorier 11 Nov '13

11 Nov '13

Hi, I've already posted before but the thread went dead. If I export a stoped vm with direct-lun disk, it creates the export without errors but doesn't export the disk. I was told that it should. How can I debugg this? Regards,

Would it make sense to install it instead of qemu-kvm? Cheers, Martijn.

[Users] *SAN LUNs* thin-provisioning : Reclaiming block device storage
by Nicolas Ecarnot 11 Nov '13

11 Nov '13

[This post is *not* about *VM* thin-provisioning] Hi, Our setup is made of an Equalogic SAN (PS6100) connected via a dedicated iSCSI network, an oVirt 3.3.0-4.el6 manager and CentOS nodes. This is working fine (thank you all). I usually create a LUN for the master storage domain, configure in thin-provisioned mode on the SAN side, and fill it with VMs until it reaches some 90%. Then I create another LUN the same way, add it as an additional storage domain, move some VM on it from the first domain and it's OK. The issue there is I have no mean to reclaim any freed storage on the master storage LUN. So the question (not *master* domain specific - any storage domain is concerned) is how to reclaim space on these domains. I began to have a closer look at how a storage domain is setup (PV, VG, LVs). I also found some hints about some mount option (unmap) that could be passed when mounting ext4 filesystems. But I guess the issue is way more complex, as LVM may add a layer between ext4 and the block device. How is the LVM setup working? I saw there was one LV by disk (and some metadata LVs), in one big VG in one big PV. Is the entire disk space allocated for the PV, or is only a partial of it is used first, then an extension (growing) is made each time some more space is needed by adding VMs? I have the opportunity to test and play with a test LUN in a test oVirt, so I fear no crash. If the only answer is "Unavailable feature", it's ok, but I just have to know. -- Nicolas Ecarnot

Hi, I just updated the wiki a little, but I'm not sure my information is 100% correct: http://www.ovirt.org/Features/MomIntegration especially regarding the status of the guest agent on various operating systems (the info in the wiki is a mess and not up-to-date). so maybe someone can provide additional information regarding ballooning of memory and the guest agent, I also updated the png but didn't upload it, because it's not finished yet, feel free to improve the dia-shape yourself (see the attachment) :-) PS: Maybe it would be cool to store such graphical overviews in their source-format in a git or in the wiki, for easier updating through other people? PPS: Is this the right ML for this kind of info or should I register for Infra or something else? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Problem adding an RHEL node/host
by Bob Doolittle 08 Nov '13

08 Nov '13

Hi, I'm trying to follow the Quick Start guide, and I can't seem to add a host. I am running oVirt 3.3 on F19 for the engine. The node is RHEL 6.4, subscribed to RH channels and fully updated: # yum repolist Loaded plugins: product-id, refresh-packagekit, rhnplugin, security, : subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register. This system is receiving updates from RHN Classic or RHN Satellite. repo id repo name status epel Extra Packages for Enterprise Linux 6 - x86_64 9,972 glusterfs-epel GlusterFS is a clustered file-system capable of sca 11 glusterfs-noarch-epel GlusterFS is a clustered file-system capable of sca 2 ovirt-stable Stable builds of the oVirt project 212 rhel-x86_64-server-6 Red Hat Enterprise Linux Server (v. 6 for 64-bit x8 11,114 repolist: 21,311 The install fails, and when I look at the host-deploy log it appears to be due to a failure for Yum to find a dependency. At Matt Curry's suggestion, I added the 'epel' repository (not mentioned in QS Guide), which I think resolved some dependencies, but I still fail as follows: 2013-11-08 13:48:49 ERROR otopi.context context._executeMethod:146 Failed to execute stage 'Package installation': [u'vdsm-4.12.1-4.el6.x86_64 requires sanlock-python', u'vdsm-4.12.1-4.el6.x86_64 requires libvirt-lock-sanlock', u'vdsm-4.12.1-4.el6.x86_64 requires sanlock >= 2.3-4'] As far as I can tell by googling around, sanlock belongs to the ovirt project. So where should it be coming from? Is something wrong with ovirt-stable? I am using: [ovirt-stable] name=Stable builds of the oVirt project baseurl=http://ovirt.org/releases/stable/rpm/EL/$releasever/ enabled=1 skip_if_unavailable=1 gpgcheck=0 I did a "yum clean; yum mkcache" just prior to initiating the Host Add from the web interface. Any suggestions? Thanks, Bob
