3.6 neccessary for upgade ? =20
If you only want to upgrade the engine to oVirt 3.5.1 - you don't need to upgrade the gluster nodes. I understand that your gluster nodes are separ= ate from the virt nodes. That is, you do not have any cluster enabled with bo= th virt + gluster service.
glusterfs 3.6 is not necessary to upgrade engine to oVirt 3.5.1. It would only be required if you were upgrading the cluster level (the compatibili= ty version) which in turn would require newer vdsm versions and gluster versions. But in your case, I think you already have your cluster running with glusterfs 3.5.2. What is the cluster compatibility version?
I'm worried what will happed with my gluster volumes after the upgrade.= .. :( =20
Plese help me. =20
Also, how can I upgrade the nodes? Need i'm to a "yum upgrade" on the compute nodes? =20
By upgrade the nodes - you mean only the compute nodes? yum upgrade on ea= ch node should work. You can also move the Host to maintenance mode and click on Reinstall or upgrade from engine.
Thanks. =20

Hi, =20 =20
No, I have only one replica beetwen two nodes. =20 =20 The third node is only a host for vms and that using this replica. =20 =20

Hello, =20 =20 =20 =20
I have an ovirt 3.5.0 cluster with three nodes and we using glust= erfs for serving backend storage for VM-s. Glusterfs are on same servers w= ith ovirt. =20 =20 =20 =20 We have Gluster 3.5.1 on all of nodes. =20 =20 =20 =20
How can I upgrade to ovirt 3.5.1 with new glusterfs? I don't want data inconsistency/data loss/split brains? =20 =20 =20 =20
Do you have a replica 3 volume setup across these 3 nodes? =20 =20 =20
Glusterfs supports rolling upgrade for replica volumes. =20 =20 =20 But there are some issues to upgrade from 3.5 to 3.6 versions (depending on version used) =20 =20 =20 Adding gluster-users & Pranith for recommended procedures. =20 =20 =20
thanks =20 =20 =20 sahina =20 =20 =20
Need I update gluster version to the latest? =20 =20 =20 =20 How I need to upgrade the nodes ? Is there any whitepaper about t= his? =20 =20 =20 =20
