newbie questions about installation using synology NAS
by bmillett＠gmail.com 20 May '19

20 May '19

I'm starting fairly fresh. Ovirt engine 4.3.3.7 on a host 2 nodes installed with ovirt-release-host-node-4.3.3.1 synology DS418 with 5 TB disks I've configured the master engine and am ready to add the nodes. My questions have to do with the order or steps . Do I need to mount /volume1/data/images/rhev from the DS418 on each of the nodes before I add them or do I just add the nodes, then define a domain using the NFS mounts from the DS418? Thanks.

Define the nodes and when you create your NFS storage domain - it will be automatically mounted on all hosts in the DC.

Re: oVirt upgrade version from 4.2 to 4.3
by Strahil 20 May '19

I would recommend you to postpone your upgrade if you use gluster (without the API) , as creation of virtual disks via UI on gluster is having issues - only preallocated can be created.

OK, Can we summarize it: 1. VDO must 'emulate512=true' 2. 'network.remote-dio' should be off ? As per this: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3/htm… We should have these: quick-read=off read-ahead=off io-cache=off stat-prefetch=off eager-lock=enable remote-dio=on quorum-type=auto server-quorum-type=server I'm a little bit confused here.

Re: Gluster VM image Resync Time
by Strahil 18 May '19

18 May '19

By default ovirt uses 'sharding' which splits the files into logical chunks. This greatly reduces healing time, as VM's disk is not always completely overwritten and only the shards that are different will be healed. Maybe you should change the default shard size.

Any plans for oVirt and SBD fencing (a.k.a. poison pill)
by hunter86_bg＠yahoo.com 18 May '19

Hello Community, Do you have any idea if SBD fencing mechanism will be implemented in the nearest future? It will be nice to be able to resset a host just like corosync/pacemaker cluster implementation.

HostedEngine Deployment fails activating NFS Storage Domain hosted_storage via GUI Step 4
