Re: [ovirt-users] Sharing iSCSI data stroage domain across multiple clusters in the same datacenter

Hi, * **Can we share the iSCSI data storage domain across multiple clusters in the same datacenter?* Following are the setup details which I tried. - One datacenter, Say DC1 - in DC1, two clusters, say CL1 and CL2 - In CL1, one host, say H1. And in CL2 one host, say H2 - iSCSI Data Storage domain is configured where external storage LUNs are exported to host H1(A host in CL1 of Datacenter). While adding H1 to CL1 is succeeded; addition of H2 in CL2 is failing with following error in vdsm.log. Traceback (most recent call last): File "/usr/share/vdsm/storage/task.py", line 873, in _run return fn(*args, **kargs) File "/usr/share/vdsm/logUtils.py", line 45, in wrapper res = f(*args, **kwargs) File "/usr/share/vdsm/storage/hsm.py", line 1020, in connectStoragePool spUUID, hostID, msdUUID, masterVersion, domainsMap) File "/usr/share/vdsm/storage/hsm.py", line 1091, in _connectStoragePool res = pool.connect(hostID, msdUUID, masterVersion) File "/usr/share/vdsm/storage/sp.py", line 630, in connect self.__rebuild(msdUUID=msdUUID, masterVersion=masterVersion) File "/usr/share/vdsm/storage/sp.py", line 1153, in __rebuild self.setMasterDomain(msdUUID, masterVersion) File "/usr/share/vdsm/storage/sp.py", line 1360, in setMasterDomain raise se.StoragePoolMasterNotFound(self.spUUID, msdUUID) StoragePoolMasterNotFound: Cannot find master domain: 'spUUID=a4dfaf64-adfa-4cfa-88d5-986fbdb2b2b2, msdUUID=741f7913-09ad-4d96-a225-3bda6d06e042' Thread-13::DEBUG::2014-07-30 15:24:49,780::task::885::TaskManager.Task::(_run) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::Task._run: 07997682-8d6b-42fd-acb3-1360f14860d6 ('a4dfaf64-adfa-4cfa-88d5-986fbdb2b2b2', 2, '741f7913-09ad-4d96-a225-3bda6d06e042', 1, None) {} failed - stopping task Thread-13::DEBUG::2014-07-30 15:24:49,780::task::1211::TaskManager.Task::(stop) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::stopping in state preparing (force False) Thread-13::DEBUG::2014-07-30 15:24:49,780::task::990::TaskManager.Task::(_decref) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::ref 1 aborting True *Thread-13::INFO::2014-07-30 15:24:49,780::task::1168::TaskManager.Task::(prepare) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::aborting: Task is aborted: 'Cannot find master domain' - code 304* Thread-13::DEBUG::2014-07-30 15:24:49,781::task::1173::TaskManager.Task::(prepare) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::Prepare: aborted: Cannot find master domain Thread-13::DEBUG::2014-07-30 15:24:49,781::task::990::TaskManager.Task::(_decref) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::ref 0 aborting True Thread-13::DEBUG::2014-07-30 15:24:49,781::task::925::TaskManager.Task::(_doAbort) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::Task._doAbort: force False Thread-13::DEBUG::2014-07-30 15:24:49,781::resourceManager::977::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-13::DEBUG::2014-07-30 15:24:49,781::task::595::TaskManager.Task::(_updateState) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::moving from state preparing -> state aborting Thread-13::DEBUG::2014-07-30 15:24:49,781::task::550::TaskManager.Task::(__state_aborting) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::_aborting: recover policy none Thread-13::DEBUG::2014-07-30 15:24:49,782::task::595::TaskManager.Task::(_updateState) Task=`07997682-8d6b-42fd-acb3-1360f14860d6`::moving from state aborting -> state failed Thread-13::DEBUG::2014-07-30 15:24:49,782::resourceManager::940::ResourceManager.Owner::(releaseAll) Owner.releaseAll requests {} resources {} Thread-13::DEBUG::2014-07-30 15:24:49,782::resourceManager::977::ResourceManager.Owner::(cancelAll) Owner.cancelAll requests {} Thread-13::ERROR::2014-07-30 15:24:49,782::dispatcher::65::Storage.Dispatcher.Protect::(run) {'status': {'message': "Cannot find master domain: 'spUUID=a4dfaf64-adfa-4cfa-88d5-986fbdb2b2b2, msdUUID=741f7913-09ad-4d96-a225-3bda6d06e042'", 'code': 304}} _*Please advise if I need to have one Storage Domain per cluster in given datacenter.*_ Thanks, Santosh. ***************************Legal Disclaimer*************************** "This communication may contain confidential and privileged material for the sole use of the intended recipient.
