[pve-devel] [RFC storage/manager 00/20] pveceph storage.cfg management

[Fabian Grünbichler]

this patch series implements storage.cfg management for pveceph-managed ceph
clusters. the following is implemented:

- add new 'pveceph' flag to RBD storages
- pveceph addstorage/lsstorages/removestorage to add/list/remove storage entries, per pool
- optionally adding/removing storages when creating/destroying a pool
- updating managed storage entries when creating/destroying a monitor

I am not 100% content with the API structure, which is the primary reason for
RFCing: currently the storage related API paths are located under
'/nodes/<node>/ceph/pool/<pool>/storage[/<storage>]'. it might be more flexible
regarding future changes to give them their own 'first-class' API endpoint like
'/nodes/<node>/ceph/storage[/<storage>]', and make <pool> a parameter?

that would allow stuff like listing all pveceph-managed storages at once. on
the other hand, 'pveceph addstorage <storage> -pool <pool>' is less natural
than 'pveceph addstorage <pool> <storage>' IMHO.

I was also thinking about renaming the API placeholder <name> to <pool_name> or
<pool> if we keep the current API schema, because with two placeholders/name
parameters it is better to be explicit.

furthermore, the whole PVE/API2/Ceph.pm is long overdue for a refactoring into
individual API modules and paths IMHO. I wonder whether it would be okay to
break backwards compatibility here since PVE 5.x does not (yet) have stable
pveceph support?
