hi, maybe i do not make you understand me fully. i am reading vdsm code, but it is hard for me to understand StorageDomain,StoragePool. before stoargeD(P) can work, engine must prepare many things. i want to know the call flow (process) which must be done to make storageS(P) work. 1.for example, what funcitons you should call if make a stoargeDomain work. poolConnectStorageServer->poolCreate->poolConnect->domainCreate->domainActivate. thanks
The setup flow is:
1. connectStorageServer (this connects the host to storage. i.e. either performs a 'mount' or iscaiadm command) 2. createStorageDomain (only required once) 3. createStoragePool (only required once)
Once you have the pool, on all hosts you perform: 1. connectStorageServer 2. connectStoragePool
And on one (and only one) of the hosts: 1. spmStart
