andrijapanicsb opened a new issue, #8391:
URL: https://github.com/apache/cloudstack/issues/8391

   Improvement request:
   
   - the capacity of the Secondary Storage seem updated/obtained from time to 
time, by SSVMs and the value (capacity) is held in the memory of the mgmt 
server.
   
   In certain cases, this becomes a very... useless... design, where the values 
can not be altered in case of edge cases where the Secondary Storage capacity 
needs to be expanded, but SSVMs are not running/existing, for whatever reason.
   
   Proposal:
   - store the capacity of the SS in the DB (perhaps op_host_capacity table, 
like for the Primary data, and other resource values)
   - Enable a global setting that will control the interval of the capacity 
collection from the NFS Secondary Storage
   - Consider offloading the work to the mgmt server, as per architecture 
design, all mgmt servers MUST be able to mount the secondary storage NFS shares 
(for various other tasks)
   - Consider implementing an explicit API call that will trigger updating the 
SS NFS capacities (in cases where the backend capacity has been expanded)
