hi,all 1.i am now not very familar with the right procedure of storage, please give me a simply introduction of their concept and relation. help me out
StoragePool,StorageDomain image,volume
You should find the following link helpful: http://www.ovirt.org/Vdsm_Storage_Terminology
As per your other questions, you might find the following guide helpul: http://www.ovirt.org/Quick_Start_Guide#Configure_Storage
Of not, please rephrase them as they're not clear enough and I'd rather not guess.
2.please help me confirm. i find only one place call mount command, which is poolConnectStorageServer. if poolConnectStorageServer is before create and active StoragePool,StorageDomain?
3.if attach is just modify metadata, not anything else?
4.sp.py, deactivateSD if i deactivate ISO storage,it finally umount masterDir, why ? if masterDir is not mastersd? thanks

I'm not that familiarized with the code myself and can't tell you without looking into it and debugging it. What I would do is - for any command I'd like the internal flow of - start at the top (All vds commands are listed when you type vdsClient, without the need to actually run something). You can then search the specific command you're interested in in the code, and see the flow there. You can obviously run a specific command if you have the correct setup and follow through with the vdsm.log to see the exact flow. You can, of course, add your own debug messages to make things clearer for you, as the vdsm log is logged to very frequently. ----- Original Message -----

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
