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
