RPC call StoragePool.connect failed: Cannot find master domain

Hi all, I'm testing the new oVirt version 4.2.6, with the ovirt-engine installed as a service in a physical host. I tried to recover an engine-backup from a previous ovirt deployment, where the ovirt-engine was self-hosted inside a VM , and it seems that all work properly, because the cluster, hosts, and network configuration was correctly redeployed. The problem was when in the new cluster, I put all the nodes on Maintenance to upgrade it, and when they go back to the UP state, the datacenter was on a Non Responsive Status, because the Master Storage Domain is Inactive, and if I try to reactivate it, I obtain this error message: Failed Activating Storage Domain gpfs_kvm on Data Center BSC-CNS I don't have any hosts in the cluster as a SPM. Due to this situacion, I've some questions: It's possible to force one host to be an SPM? I failed when I put all the nodes on maintenance to upgrade, beacause it's better to maintain one host active as an SPM to protect the cluster, and the storage? Maybe the restored config from a diferent architecture (hosted-engine vs engine installed on host), can affect the Storage? (Previously the Master Storage Domain was on NFS, but I delete it and changed the role of Master to one Posix domain added) At log level on one compute, I can see this events: 2018-09-19 11:40:11,878+0200 INFO (jsonrpc/5) [vdsm.api] FINISH connectStoragePool error=Cannot find master domain: u'spUUID=32168096-b763-11e8-a7aa-000af7b8b6ba, msdUUID=cb99c414-0d93-41b9-9396-d8a607652b49' from=::ffff:10.2.1.101,58538, task_id=eedeba4d-99bc-4e18-8f24-f501b73e0da6 (api:50) 2018-09-19 11:40:11,879+0200 ERROR (jsonrpc/5) [storage.TaskManager.Task] (Task='eedeba4d-99bc-4e18-8f24-f501b73e0da6') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in connectStoragePool File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 1035, in connectStoragePool spUUID, hostID, msdUUID, masterVersion, domainsMap) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 1097, in _connectStoragePool res = pool.connect(hostID, msdUUID, masterVersion) File "/usr/lib/python2.7/site-packages/vdsm/storage/sp.py", line 700, in connect self.__rebuild(msdUUID=msdUUID, masterVersion=masterVersion) File "/usr/lib/python2.7/site-packages/vdsm/storage/sp.py", line 1274, in __rebuild self.setMasterDomain(msdUUID, masterVersion) File "/usr/lib/python2.7/site-packages/vdsm/storage/sp.py", line 1495, in setMasterDomain raise se.StoragePoolMasterNotFound(self.spUUID, msdUUID) StoragePoolMasterNotFound: Cannot find master domain: u'spUUID=32168096-b763-11e8-a7aa-000af7b8b6ba, msdUUID=cb99c414-0d93-41b9-9396-d8a607652b49' 2018-09-19 11:40:11,879+0200 INFO (jsonrpc/5) [storage.TaskManager.Task] (Task='eedeba4d-99bc-4e18-8f24-f501b73e0da6') aborting: Task is aborted: "Cannot find master domain: u'spUUID=32168096-b763-11e8-a7aa-000af7b8b6ba, msdUUID=cb99c414-0d93-41b9-9396-d8a607652b49'" - code 304 (task:1181) 2018-09-19 11:40:11,879+0200 ERROR (jsonrpc/5) [storage.Dispatcher] FINISH connectStoragePool error=Cannot find master domain: u'spUUID=32168096-b763-11e8-a7aa-000af7b8b6ba, msdUUID=cb99c414-0d93-41b9-9396-d8a607652b49' (dispatcher:82) 2018-09-19 11:40:11,880+0200 INFO (jsonrpc/5) [jsonrpc.JsonRpcServer] RPC call StoragePool.connect failed (error 304) in 0.31 seconds (__init__:573) 2018-09-19 11:40:11,907+0200 INFO (jsonrpc/1) [vdsm.api] START getSpmStatus(spUUID=u'32168096-b763-11e8-a7aa-000af7b8b6ba', options=None) from=::ffff:10.2.1.101,58538, task_id=4133fa8c-88f8-44c5-a8b8-18ac6c67771e (api:46) 2018-09-19 11:40:11,907+0200 INFO (jsonrpc/1) [vdsm.api] FINISH getSpmStatus error=Unknown pool id, pool not connected: (u'32168096-b763-11e8-a7aa-000af7b8b6ba',) from=::ffff:10.2.1.101,58538, task_id=4133fa8c-88f8-44c5-a8b8-18ac6c67771e (api:50) 2018-09-19 11:40:11,908+0200 ERROR (jsonrpc/1) [storage.TaskManager.Task] (Task='4133fa8c-88f8-44c5-a8b8-18ac6c67771e') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in getSpmStatus File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 48, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 634, in getSpmStatus pool = self.getPool(spUUID) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 350, in getPool raise se.StoragePoolUnknown(spUUID) StoragePoolUnknown: Unknown pool id, pool not connected: (u'32168096-b763-11e8-a7aa-000af7b8b6ba',) 2018-09-19 11:40:11,908+0200 INFO (jsonrpc/1) [storage.TaskManager.Task] (Task='4133fa8c-88f8-44c5-a8b8-18ac6c67771e') aborting: Task is aborted: "Unknown pool id, pool not connected: (u'32168096-b763-11e8-a7aa-000af7b8b6ba',)" - code 309 (task:1181) 2018-09-19 11:40:11,908+0200 ERROR (jsonrpc/1) [storage.Dispatcher] FINISH getSpmStatus error=Unknown pool id, pool not connected: (u'32168096-b763-11e8-a7aa-000af7b8b6ba',) (dispatcher:82) 2018-09-19 11:40:11,908+0200 INFO (jsonrpc/1) [jsonrpc.JsonRpcServer] RPC call StoragePool.getSpmStatus failed (error 309) in 0.01 seconds (__init__:573) I tried to base my situation on other cases that other people reported before, but nothing fits with exactly my logged errors.

Errors when migrate VMWare to RHV
by Xiaoyu Liu 18 Sep '18

18 Sep '18

Hi All I met two kinds of error when I migrate VMWare VM to RHV using virt-v2v. Any suggestion? Thank in advanced. 1: After executing the next command to migrate a VM, windows2008R2.ova from VMWare to RHV, everything looks OK in command line interface. But we could not find the migrated VM in RHV web console. Why? >virt-v2v -i ova windows2008R2.ova -on windows2008R4.ova -o libvirt -of qcow2 -os Appliances1 -n ovirtmgmt 2: When executed the next command to migrate a VM from VMWare to RHV, an error message came up >virt-v2v -ic esx://XX.XX.XX.XX/?no_verify=1 -os /data/images -of raw --bridge vdsm-ovirtmgmt test_linux Error message virt-v2v: Output pool /data/images is not a valid storage pool.

gdeploy fails for unsupported disk (script problem)

It seems as though there is a problem with the grafton sanity check script. It took me a moment to spot the error below. Note the inconsistencies in the host names. changed: [obe.cyber-range.lan] (this is the correct piece of info) ping: ovir-be.cyber-range.lan (the ping portion changed the host name somehow) I'm not quite strong enough with scripting to fix it.

Supported Kernel upgrade (4.15+) for AMD EPYC hardware?
by pousaduarte＠gmail.com 18 Sep '18

18 Sep '18

Hi, Currently, I have oVirt managing a cluster of EPYC machines. Before deploying oVirt, though I ran a suite of benchmarks to attempt to determine whether there is a performance benefit introduced by newer kernels, and indeed there is. The benefit is workload dependant, but a benefit nonetheless. Meanwhile, I have also installed the latest stable kernel from elrepo.org on one of the oVirt nodes to test the waters and it seems to be working, that said I'm pretty sure this is not a supported configuration, so before applying the change to the whole cluster I would like to know if there is an alternative/expected drawbacks to doing this. If at all possible, I would like to retain the performance benefit while deploying a tested and supported 4.15+ kernel, such as to not jeopardize system stability.

LVM Mirroring
by René Koch 18 Sep '18

18 Sep '18

Hi list, Is it possible to use LVM mirroring for FC LUNs in oVirt 4.2? I've 2 FC storages which do not have a replication functionality. So the idea is to create a LVM mirror using 1 LUN of storage 1 und 1 LUN of storage 2 for replicating data between the storages on host level (full RHEL 7.5 not oVirt Node). With e.g. pacemaker and plain KVM this works fine. Is it possible to have the same setup with oVirt 4.2? Thanks a lot. Regards, René
