Internal Engine Error while adding a new (distribute glusterfs) Storage Domain
by Konstantinos Christidis 14 Jul '15

14 Jul '15

Hello, I created (through oVirt web) a GlusterFS distributed volume with four bricks. When I try to add a New Domain - GlusterFS Data I am getting Error while executing action Add Storage Connection: Internal Engine Error and Error validating master storage domain: ('MD read error',) Full logs engine.log - https://paste.kde.org/pefcwndgc/zamd2o/raw vdsm.log - https://paste.kde.org/pxf91znwq/6mhrg3/raw Gluster info/options - https://paste.kde.org/pjfauvisg/grfrvj/raw (oVirt3.6/Centos7) ps: My installation seems to work only with replica-3 oVirt Optimized volumes. Every other combination fails with the error above. Any help would be appreciated. Thanks, K.

ovirt-Node + hosted engine question
by Alan Murrell 14 Jul '15

14 Jul '15

Hi All. As I was perusing my e-mails from this list earlier today one that caught my attention was one that had to do with ovirt-node and hosted engine. It appeared as though it is possible to install hosted engine on a ovirt-node "host", and indeed, when I installed ovirt-node into a VirtualBox VM to poke around, there is a "hosted engine" option in the menu where you can enter a URL for an ISO/pxe source for OS installtion. I just want to clarify the following questions: 1.) Is it possible to install ovirt-node, and then install a hosted engine? 2.) If the answer to 1.) is "Yes", does it require some sort of NFS-enabled storage, or can you confgiure local storage on ovirt-node and install the engine to there? 3.) Is it possible to create NFS-enabled storage on ovirt-node? 4.) Can you install the hosted engine onto external NFS storage, then move/migrate it to local storage on ovirt-node? I am thinking of a "lab" situation where there is only one server, but gobs of RAM and storage. Running ovirt-node as the "host" would require fewer space resources (not that I would necessarily be hurting for space, but any extra I could squeeze out would not be unwelcome). Thanks! :-) -Alan

Engine missing snapshot which is used by VM
