Hi, Can anyone share their experience on deploying hosted-engine with GlusterFS cluster?
I managed to setup a GlusterFS cluster and started to deploy hosted engine. At first stage I was beaten by firewall rules - the deployment process interrupted at GlusterFS config stage. After fixing the rules I got engine up and running, but the host is non-operational state still. Logged in to Web UI -> and see 2 action points: "Gluster command failed on server" and Gluster status is disconnected for this server" This is a bit strange, since the cluster was properly detected during deployment and deployment script was supposed to configure the cluster. --== STORAGE CONFIGURATION ==-- Please specify the storage you would like to use (glusterfs, iscsi, fc, nfs3, nfs4)[nfs3]: glusterfs [ INFO ] Please note that Replica 3 support is required for the shared storage. Please specify the full shared storage connection path to use (example: host:/path): xxxx.xxxxx.xx:/oVirt [ INFO ] GlusterFS replica 3 Volume detected Do you want to configure this host and its cluster for gluster? (Yes, No) [No]: Yes [ INFO ] GlusterFS replica 3 Volume detected Any ideas how to fix this? Thanks in advance!
