[Engine-devel] engine-core redundant instantiation of mappers
by Yair Zaslavsky 24 Jan '12

24 Jan '12

Hi all, I am refactoring now DiskImageDAODbFacadeImpl. As part of my work, I'm also defining there a Spring-JDBC mapper , similar to other ParameterizedRowMapper based mappers we have in code (i.e DbUserDAODbFacadeImpl has one) Looks like in our DAO getXXXX methods we instantiate these mapper objects (each method creates a new mapper object). Can anyone see a reason , in case a mapper object is stateless (and from what I see, they are) - why not to have a single instantiation per mapper type (i.e - Have a MapperUtils class, with static methods like MapperUtils.getDiskImageMapper() ? IMHO this can save us some unnecessary instanatiations and improve performance Yair

[Engine-devel] Engine UI only: cleaning EAR from deployment folder may be required.
by Asaf Shakarchi 23 Jan '12

23 Jan '12

Hello, Some maven re-factoring (for UI modules only) patch (http://gerrit.ovirt.org/#change,689) has just merged, You may encounter weird UI behaviours that might occur because some unnecessary data still exist in the deployed EAR folder. If so please follow these steps: 1) Clean then build (the entire engine) with Pgwt-admin,gwt-user profiles 2) Fully remove the ovirt.ear from your JBOSS deployment folder. 3) cd OVIRT_ENGINE/ear then 'mvn install -Pdep' Thanks, Regards, Asaf

[Engine-devel] running jboss as 7 with openjdk
by Jon Choate 22 Jan '12

22 Jan '12

I keep getting a message that it can't find sun.security.krb5.KrbException. Any ideas? Jboss-as-5 ran ovirt-engine just fine with openjdk.

[Engine-devel] Question about CloneVMFromSnapshot feature in context of shared disks and direct LUNs-based disks
by Yair Zaslavsky 22 Jan '12

22 Jan '12

Hi all, Following the upstream meeting dated Wednesday January 18th, 2012 - I presented the clone VM from snpashot feature and we discussed the feature behaviour. Two issues that were raised are the behaviour of the feature in context of shared disks and direct LUNs-based disks - On one hand, if we copy&collapse such images - this may yield to data corruption (think of a scenario where the source and destination VMs use the same disk). On the other hand - if we decide not to copy&collapse - the target VM will have missing VM and its state will not totally reflect the logical state. One of the solution raises is to mark such disks (at the destination) as unplugged, allowing the administrator the ability to plug them (understanding of course the consequences). I would like to receive inputs on this issue Kind regards, Yair

[Engine-devel] getDeviceList should report partioned devices, too
by Dan Kenigsberg 22 Jan '12

22 Jan '12

Hi Lists, One cannot create a PV on a partitioned device, and therefor such devices where not reported to Engine. This proved surprising to users who woder where their LUN disappeared. Vdsm should report all devices, and ovirt-engine should mark partitioned devices as unworthy of a PV. In the future, Vdsm may allow to forcefully remove a partition table from a device, to make it usable as a PV. Douglas (CCed) would take resposibilty on the Vdsm side. Initial patch at http://gerrit.ovirt.org/944 sports a backword-compatible API. Who's taking this on Engine? This involves GUI, too, as partitioned devices should probably be displayed greyed-out. Dan.

[Engine-devel] backup/restore your git branch out of git repository
by Eli Mesika 22 Jan '12

22 Jan '12

Hi I had last week a corrupted git repository caused possibly by a forced shutdown, I had to re-clone my repository to a new place and apply all my changes. Lucky me , I had a backup out of the git repository. The following takes 1 min to apply and may save you lot of work in case something gone wrong. The following command will create a directory named as your current git branch under ~/backup/patch and will backup there all your branch work copy the following lines to your ~/.bashrc alias gitbackup='br=$(git symbolic-ref HEAD 2>/dev/null | cut -d "/" -f3);rm -f *.patch;git format-patch origin/master;mkdir -p ~/backup/patch/$br;mv *.patch ~/backup/patch/$br' alias gitrestore='br=$(git symbolic-ref HEAD 2>/dev/null | cut -d "/" -f3);git stash; git checkout master;git checkout -b "$br-restore-$(date "+%d-%m-%y--%H-%M")";cp ~/backup/patch/$br/*.patch .;for f in $(ls -1 *.patch) ;do git am --ignore-whitespace $f;done' > source ~/.bashrc to backup your branch just run from your current git branch > gitbackup In any case you have messed up with your branch (and you have a backup), you can run from your current git branch > gitrestore this will create a new restored branch named <your-original-branch-name>-restore-<date> and apply on it your backed up patches.
