Hi

For a production environment i would not build a 2 node gluster, i wou= =3D ld build at least 3 nodes to have it much easier with the quorum.

Taking into account that you can use commodity hardware i would also s= =3D uggest to split the services, but i would go for at least 3 gluster nodes = =3D =3D96 which add up to at least 5 nodes for a HA system.

If you want 4 in any case, then my suggestion would be to go for 4 rep= =3D licas, each node has anything that it needs to run and you can basically us= =3D e NFS to localhost for the storage which would make the nodes always access= =3D the local storage for the VMS, availability wise it makes no difference.

Cheers

Subject: Re: [ovirt-users] gluste= r =3D config in 4 node cluster

Hi,

As for me, I would build one cluster with gluster service only based on two= =3D nodes (replica 2), and the other one with virt service only based on other= =3D two nodes. I think this variant is more scalable in future.

PS. I am a new in oVirt, so do not except that I am wrong.

Hell= o,
How to optimal configure 4 node cluster for any one node goes to = =3D ; maintenance without stopping VM ??

a) replica 4 - but it takes a lot of space
b) disperse 3+1 ( raid 5 ) - but bad performance and not visible by oVi= =3D rt 3.7.2
c) stripe2+replica2 =3D3D but VM paused

any other idea ?
regs.
