GlusterFS is a bit different to the other shared storage as it needs to see the same files in both the system and images datastores. It needs both.
Cluster 0 Mount gluster_vol_0 in /storage Link /storage -> /var/lib/one/datastores/100 (system) Link /storage -> /var/lib/one/datastores/101 (images) Cluster 1 Mount gluster_vol_1 in /storage Link /storage -> /var/lib/one/datastores/102 (system) Link /storage -> /var/lib/one/datastores/103 (images) Cluster 2 Mount gluster_vol_2 in /storage Link /storage -> /var/lib/one/datastores/104 (system) Link /storage -> /var/lib/one/datastores/105 (images) Frontend Mount gluster_vol_0 in /storage/0 Mount gluster_vol_0 in /storage/1 Mount gluster_vol_0 in /storage/2 Link /storage/0 -> /var/lib/one/datastores/100 (system) Link /storage/0 -> /var/lib/one/datastores/101 (images) Link /storage/1 -> /var/lib/one/datastores/102 (system) Link /storage/1 -> /var/lib/one/datastores/103 (images) Link /storage/2 -> /var/lib/one/datastores/104 (system) Link /storage/2-> /var/lib/one/datastores/105 (images) On Sat, Sep 20, 2014 at 7:28 PM, Amier Anis <myma...@gmail.com> wrote: > Dear Team, > > I would like to know little bit more about system datastore + gluster and > cluster. > > node 0 - FrontEnd > node 1 - Hypervisor 1 > node 2 - Hypervisor 2 > > Cluster 1 > node 3 Hypervisor 3 > node 4 Hypervisor 4 > > Cluster 2 > node 5 Hypervisor 5 > node 6 Hypervisor 6 > > GlusterFS Storage 1 - mount to frontend to datastore 0 > GlusterFS Storage 2 - mount to frontend to datastore 100 - for Cluster 1 > GlusterFS Storage 3 - mount to frontend to datastore 101 - for Cluster 2 > > I believe that all glusterfs storage need to mount to Frontend and > hypervisor node. > > my question is > > Should I mount datastore 0 to all hypervisor node even it is clusters? or > Do i only mount for each datastore to each clusters. let say GlusterFS > Storage 1 for non-cluster node, glusterfs 2 for cluster 2 and etc. > In cluster 1, I only mount glusterfs 2 and set it as system datastore and > image datastore. no datastore 0,1,2 in cluster 2. > > Which is the proper one? > How do I set glusterfs as system and image datastore in opennebula.
