[PVE-User] GlusterFS VM failover

[Angel Docampo]

Hi there,

Mmmm, if you use /etc/fstab or glusterfs client, you will be accessing 
the gluster via FUSE.

And that s*cks.

I do a trick on my proxmox cluster, as well gluster cluster. I do have 
one 10Gb interface dedicated to gluster on each node, and another 1Gb 
interface dedicated to proxmox cluster. So, in hosts, my config is more 
or less this one.

#PROXMOX NODES
10.0.0.1 pve01
10.0.0.2 pve02
#GLUSTER NODE
192.168.100.10  g01
192.168.100.20  g02

Until this point, completely normal, now, on the first node (pve01/g01) 
y put on hosts
192.168.100.10 gluster

And this other hosts line on node pve02/g02
192.168.100.20 gluster

So, on proxmox GUI I mount gluster:VOLUMENAME. Each node mounts its own 
mountpoint and on the redhat cluster, the resource is called the same: 
gluster.

Its a trick if your virtualization nodes are also storage nodes, which 
is my case.
Hope it helps.
