Description Boriso 2018-04-25 06:48:55 UTC
Description of problem:
On a big environment if an inventory item (vm or host) is deleted in the process of the refresh (after the top level collections were collected but the lower level collections like disks or nics were not) the refresh will fail.

Version-Release number of selected component (if applicable):
All version

How reproducible:

Steps to Reproduce:
1. Add a delay to the method collect_top_level_futures in inventory collection:
1.1. go to app/models/manageiq/providers/redhat/infra_manager/inventory/strategies/v4.rb


1.2. add the following lines before the last line of the method (before res):
_log.info(">>>>>>>>>>>>>>>>>>>>>>>>>> Time to delete vms!!!")
(line 127 currently)
1.3 add the following line before the method definition (line 122 currently)
include Vmdb::Logging

So it should look like:

    include Vmdb::Logging
    def collect_top_level_futures
      res = {}
      TOP_LEVEL_INVENTORY_TYPES.each { |inv_name| res[inv_name.to_sym] = collect_inv_future(inv_name.to_sym) }
      _log.info(">>>>>>>>>>>>>>>>>>>>>>>>>> Time to delete vms!!!")

before the method defenition (line 123 currently)
2. Start a full refresh
3. Monitor the evm.log, when you see ">>>>>>>>>>>>>>>>>>>>>>>>>> Time to delete vms!!!"
in the log, delete a vm form the provider with its disks before a minute passes.

Actual results:
The refresh fails

Expected results:
The refresh succeeds.

Additional info:
The state of the deleted VM immediately after refresh is not so important, it will be dealt with later as the even of it deletion will be processed after the refresh.
