i can't see any justification for the 'gluster' prefix, as this is only additional /service/ provided by the project, and Gluster now is a part of the RHT. I believe there needs to be an indication which service this is about. If we will support provisioning other storage types which also have volumes then we'd want a way to differentiate. However, isn't there a way to simply add gluster as the name space? i.e. somthing like: /api/gluster/.../volumes ? (instead of 'cluster' as it is redundant imho)
A gluster volume is a cluster level entity, and hence "/api/.../clusters/{cluster:id}" seems like the right parent URI for the gluster volumes collection resource.
that's true for all other root entities as well: - VM is DC/cluster level - template is DC level - disk is storage domain level - network is DC level - hosts are cluster level (for now)
yet all of them have their own root collections as well.
I think glustervolumes seems safest/most reasonable for now (either at cluster level or root level as well)
does it make sense to also have gluster/bricks ? if so, I would nest it, i.e. gluster/{volumes|bricks|...}
bricks are host level, afair they are not used like this at all. gluster/xxx is interesting as well, though not parallel to current virt mappings (storage_domains, disks, etc., being root collections) shireesh - any thoughts about this approach: - do you want volumes as root collection, or only under cluster - if root, should these be glustervolumes like other root collection, or the under a gluster collection.
According to Geert, a key question in deciding whether gluster-volumes should exist in root collection is: are volumes potentially moveable between clusters? The answer, according to Shireesh, is no, and therefore Geert believes that the volumes should be under cluster. (Geert or Shireesh - if I misquoted you, please correct me). Bricks logically compose volumes, and thus are modelled under volumes.
