core: allow current master domain to be selected as the new master Currently the current master domain cannot be selected as the new master, which can cause to the system to not be able to recover in case that it's the only available domain. This patch allows to perform reconstruct using the master domain in case that we know that it's accessible - 1. Getting WrongMasterDomain error from vdsm means that we could get to the master domain metadata. NOTE: in that case, the reconstruct command will be executed with parameter indicating that the current master can be selected as the new master - but the host that return the WrongMasterDomain error or the master domain id as the master domain id as the id of the domain to reconstruct to aren't being passed to the command - this is being done to avoid possible issues (for example: failing to reconstruct to that domain although we can read the metadata, keep trying through the same host..etc). The intention here is to improve the current situation for most of the usecases. 2. When the master domain info in the db is different then the info received from getStoragePoolInfo.
