Re: [Gluster-devel] [Gluster-users] Update: Support for GLUSTERFS storage domain in VDSM & oVirt available now !

[Deepak C Shetty]

Quick Update:
    Ability to create GLUSTERFS_DOMAIN from oVirt web UI is now upstream.

http://gerrit.ovirt.org/#/c/8834/
http://gerrit.ovirt.org/#/c/8983/
http://gerrit.ovirt.org/#/c/13176/


This provides the capability to create a new DC, cluster of type GLUSTERFS, ability to add new host to the GLUSTERFS DC/Cluster and create a new storage domain of type GLUSTERFS and run VMs off it.

The VMs created using GLUSTERFS_DOMAIN exploits the QEMU-GlusterFS native integration (QEMU's gluster block backend)
With this the complete oVirt virt-stack is now enabled for GLUSTERFS!

Hi All,
    Just a quick update.

Support for GLUSTERFS_DOMAIN is now available in VDSM upstream. This helps VDSM exploit Gluster natively by using the QEMU's gluster block backend.
For those who are interested, the entire patchseries can be viewed @ http://gerrit.ovirt.org/#/q/project:vdsm+branch:master+topic:gluster_domain_support,n,z

As the commit msg says...

This patch introduces a new storage domain of type
GLUSTERFS_DOMAIN, which uses gluster as the storage backend.

In GLUSTERFS_DOMAIN, vdsm creates the storage domain by mounting
the gluster volume (akin to nfs mounting export path). VMs
created using this domain exploit the QEMU's gluster block
backend. Instead of accessing the vmdisk as a file path, it
accesses the vmdisk as a network disk device, served by gluster
server/volume.

With this the virt. stack comprising of qemu, libvirt, vdsm is now enabled to exploit GlusterFS natively.

The next step is to have support for Gluster Storage domain in oVirt web UI, which is a WIP, which once done will complete the entire virt. stack enablement for Gluster.
More details about this can be seen @ http://gerrit.ovirt.org/#/q/status:open+project:ovirt-engine+branch:master+topic:glusterfs,n,z

oVirt feature page for Gluster storage domain support can be viewed @ http://wiki.ovirt.org/Features/GlusterFS_Storage_Domain

thanx,
deepak
