[Ovirt-devel] PATCH: constrain storage_pool to avoid duplicate targets

[steve linabery]

Hi Ovirt,

This little patch attempts to do the following:
0) Add a flash notice when storage pool creation fails and redirect to
storage/show
1) Use validates_uniqueness_of in isci and nfs storage pool classes
2) Add a "FIXME" to storage/new.rhtml and storage/new2.rhtml so that
the tip will stop breaking my page flow :)

I think 1) is sufficient for avoiding both duplicate storage pool
targets as well as duplicate storage volumes, since afaict volumes are
only detected/created after pools.

Hope this helps,
Steve Linabery
