Comment 3 Martin Sivák 2014-01-16 15:07:25 UTC
1) Agent is not able to get sanlock lease

Exception: Failed to initialize sanlock: cannot get lock on host id 1: host already holds lock on a different host id

2) There is only this single host connected to the cluster and because this host does not have an ID and thus haven't published it's state yet

The metadata file contains only zeros:

[root@slot-6 ha_agent]# hexdump hosted-engine.metadata 
0000000 0000 0000 0000 0000 0000 0000 0000 0000

3) Because of this the get_all_stats_for_service_type returns an empty string
4) Because of this the RPC brokerlink.get_stats_from_storage returns only "success "
5) And the brokerlink._checked_communicate expects success to contain at least one additional part
6) Because it does not, it falls back to the else clause that reports Request failed: success

I think the sanlock still holds an old lease from previous test run and does not want to give it up and take a new one from a fresh set of IDs (following an environment cleanup)

Comment 4 movciari 2014-01-22 14:36:38 UTC
sanlock cleanup and new setup solved problem

Comment 5 Doron Fediuck 2014-02-10 13:59:42 UTC
(In reply to movciari from comment #4)
> sanlock cleanup and new setup solved problem

So is this still relevant? If not, we'll close it.
