But I've stopped all my (monitoring) processes using the API. Restarting ovirt-engine and vdsm did not resolve the issue. Both nodes and engine server are running oVirt 3.3.1 on CentOS 6.4 This may be a red herring but the values of disk statistics read through the API are "static"/unchanging. Any clues on whether these messages are serious and any ideas on how to stop them spamming my system logs?

[Users] GlusterFS Distributed Replicate
by gregoire.leroy＠retenodus.net 20 Dec '13

20 Dec '13

Hello, As I said in a previous email, I have this configuration with Ovirt 3.3 : 1 Ovirt Engine 2 Hosts Centos 6.5 I successfully setup GlusterFS. I created a distributed replicate volume with 2 bricks : host1:/gluster and host2:/gluster. Then, I created a storage storage_gluster POSIXFS with the option glusterfs and I gave the path "host1:/gluster". First, I'm rather surprised I have to specify an host for the storage as I wish to have a distribute replicated storage. I expected to specify both hosts. Then I create a VM on this storage. The expected behaviour if I shutdown host1 should be that my VM keeps running on the second brick. Yet, not only I lose my VM but host2 is in a non operationnal status because one of its data storage is not reachable. Did I miss something in the configuration ? How could I get the wanted behaviour ? Thanks a lot, Regards, Grégoire Leroy
