CLOUDSTACK-9366: Capacity of one zone-wide primary storage ignoredDisable and
Remove Host operation disables the primary storage capacity.
Steps to replicate:
Base Condition: There exists a host and storage pool with same id
Steps:
1. Find a host and storage pool having same id
2. Disable the host
3. CPU(1) and MEMORY(0) capacity in op_host_capacity for above host is disabled
4. STORAGE(3) capacity in op_host_capacity for storage pool with id same as
above host is also disabled
RCA:
'host_id' column in 'op_host_capacity' table used for storing both storage pool
id (for STORAGE capacity) and host id (MEMORY and CPU). While disabling a HOST
we also disable the capacity associated with host.
Ideally while disabling capacity we should only disable MEMORY and CPU
capacity, but we are not doing so.
Code Path:
ResourceManagerImpl.doDeleteHost() ->
ResourceManagerImpl.resourceStateTransitTo() ->
CapacityDaoImpl.updateCapacityState(null, null, null, host.getId(),
capacityState.toString())
updateCapacityState is updating disabling all entries which matches the
host_id. This will also disable a entry having storage pool id same as that of
host id.
Changes:
introduced new capacityType parameter in updateCapacityState method and
necessary changes to add capacity_type clause in sql
also fixed incorrect sql builder logic (unused code path for which it is never
surfaced )
Added marvin test to check host and storagepool capacity when host is disabled
Test Result:
```
Before Fix:
mysql> select ohc.host_id, ohc.`capacity_state`, case capacity_type when 0
then 'MEMORY' when 1 then 'CPU' ELSE 'STORAGE' END as 'capacity_type' ,
total_capacity, case capacity_type when 0 then 'HOST' when 1 then 'HOST'
ELSE 'STORAGE POOL' END as 'HOST/STORAGE POOL' from op_host_capacity ohc
where host_id=3;
