And what exactly is your problem?
Real life example. Database resource depends on storage resource(s).
There are multiple filesystems/volumes with database files. Database
admin needs to increase available space. You add new storage,
configure it in cluster ... pooh, your database is restarted.
“configure it in cluster” hmmm
if you’re expanding an existing mount point, then I’d expect you don’t need to
update the cluster.
if you’re creating a new mount point, wouldn’t you need to take the db down in
order to point to the new location?
No. Those database I worked with can use multiple storage locations at
the same time and those storage locations can be added (and removed) online.
