Do you have a replica 3 volume setup across these 3 n= =3D odes?

Glusterfs supports rolling upgrade for replica volumes.

Hi,

Is glusterfs 3.6 is neccessary for ovirt 3.5.1?

I have 3.5.2 at this moment.

3.6 neccessary for upgade ?=C2=A0

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 separate from the virt nodes. That is, you do not have any cluster enabled with both 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 compatibility 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... :(

Plese help me.

Also, how can I upgrade the nodes? Need i'm to a "yum upgrade" on the compute nodes?

By upgrade the nodes - you mean only the compute nodes? yum upgrade on each node should work.
You can also move the Host to maintenance mode and click on Reinstall or upgrade from engine.

Thanks.

Hi,

No, I have only one replica beetwen two nodes.

The third node is only a host for vms and that using this replica.

Thanks

Hello,

I have an ovirt 3.5.0 cluster with three nodes and we using glusterfs for serving backend storage for VM-s. Glusterfs are on same servers with ovirt.
We have Gluster 3.5.1 on all of nodes.

How can I upgrade to ovirt 3.5.1 with new glusterfs? I don't want data inconsistency/data loss/split brains?

Do you have a replica 3 volume setup across these 3 nodes?

Glusterfs supports rolling upgrade for replica volumes.
But there are some issues to upgrade from 3.5 to 3.6 versions (depending on version used)
Adding gluster-users & Pranith for recommended procedures.

thanks
sahina

Need I update gluster version to the latest?

How I need to upgrade the nodes ? =C2=A0Is there any whitepaper about this?

Thanks in advance,

Tibor

Hi Sahina,

Unfortunately my compute nodes and gluster nodes are on same server= =3D s. I running my VMs on the gluster nodes and vica-versa.
Al= =3D so, my ovirt portal is running on the first node, that is an gluster and co= =3D mpute node too.

I have a gluster based installation with thre= =3D e servers, two for replica&VMs, one for VMs-s only.

This = =3D is a productive environment, so I'm affraid so much of upgrading...:(.I don= =3D 't want glusterfs mistakes, split-brains, etc..)

A= =3D lso, I could make little downtime for upgrading, but I'm need to know what = =3D is the trustable upgrade procedure. Is there an official upgrade documentat= =3D ion for ovirt, that is contain the glusterfs upgrde methods?

= =3D

My cluster level is 3.5.

Thanks a lot.

Hi,

Is glusterfs 3.6 is neccessary for ovirt 3.5.1?

I have 3.5.2 at this moment.

3.6 neccessary for upgade ?

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 separate from the virt nodes. That is, you do not have any cluster enabled with both 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 compatibility 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... :(

Plese help me.

Also, how can I upgrade the nodes? Need i'm to a "yum upgrade" on the compute nodes?

By upgrade the nodes - you mean only the compute nodes? yum upgrade on each node should work.
You can also move the Host to maintenance mode and click on Reinstall or upgrade from engine.

Thanks.

Tibor

Hi,

No, I have only one replica beetwen two nodes.

The third node is only a host for vms and that using this replica.

Thanks

Hello,

I have an ovirt 3.5.0 cluster with three nodes and we using glusterfs for serving backend storage for VM-s. Glusterfs are on same servers with ovirt.
We have Gluster 3.5.1 on all of nodes.

How can I upgrade to ovirt 3.5.1 with new glusterfs? I don't want data inconsistency/data loss/split brains?

Do you have a replica 3 volume setup across these 3 nodes?
Glusterfs supports rolling upgrade for replica volumes.
But there are some issues to upgrade from 3.5 to 3.6 versions (depending on version used)
Adding gluster-users & Pranith for recommended procedures.

thanks
sahina

Need I update gluster version to the latest?

How I need to upgrade the nodes ? Is there any whitepaper about this?

Thanks in advance,

Tibor

Hi Sahina,

Unfortunately my compute nodes and gluster nodes are on same servers. I running my VMs on the gluster nodes and vica-versa.=C2=A0

Also, my ovirt portal is running on the first node, that is an gluster and compute node too.

Is this hosted-engine setup? Have you looked at http://www.ovirt.org/Hosted_Engine_Howt= o#Upgrade_Hosted_Engine ?

I have a gluster based installation with three servers, two for replica&VMs, one for VMs-s only.

If you're upgrading from oVirt 3.5 to 3.5.1 - there's no new dependency on glusterfs. So, you could decide not to upgrade glusterfs and just upgrade the vdsm on the nodes.

This is a productive environment, so I'm affraid so much of upgrading...:(.I don't want glusterfs mistakes, split-brains, etc..)

Also, I could make little downtime for upgrading, but I'm need to know what is the trustable upgrade procedure. Is there an official upgrade documentation for ovirt, that is contain the glusterfs upgrde methods?

There are separate documentations - for oVirt upgrade and glusterfs upgrade. No mechanism to upgrade glusterfs on nodes from within oVirt.

My cluster level is 3.5.

Thanks a lot.

Hi,

Is glusterfs 3.6 is neccessary for ovirt 3.5.1?

I have 3.5.2 at this moment.

3.6 neccessary for upgade ?=C2=A0

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 separate from the virt nodes. That is, you do not have any cluster enabled with both 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 compatibility 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... :(

Plese help me.

Also, how can I upgrade the nodes? Need i'm to a "yum upgrade" on the compute nodes?

By upgrade the nodes - you mean only the compute nodes? yum upgrade on each node should work.
You can also move the Host to maintenance mode and click on Reinstall or upgrade from engine.

Thanks.

Tibor

Hi,

No, I have only one replica beetwen two nodes.

The third node is only a host for vms and that using this replica.

Thanks

Hello,=

I have an ovirt 3.5.0 cluster with three nodes and we using glusterfs for serving backend storage for VM-s. Glusterfs are on same servers with ovirt.

We have Gluster 3.5.1 on all of nodes.

How can I upgrade to ovirt 3.5.1 with new glusterfs? I don't want data inconsistency/data loss/split brains?

Do you have a replica 3 volume setup across these 3 nodes?

Glusterfs supports rolling upgrade for replica volumes.
But there are some issues to upgrade from 3.5 to 3.6 versions (depending on version used)
Adding gluster-users & Pranith for recommended procedures.

thanks
sahina

Need I update gluster version to the latest?

How I need to upgrade the nodes ? =C2=A0Is the= re any whitepaper about this?

Thanks in advance,

Tibor
