[Users] NFS domain and LVM
by René Koch (ovido) 07 May '13

07 May '13

Hi, I just rebooted my NFS server which hosts a ISO domain which is used by RHEV 3.1 and oVirt 3.2. In both environments the ISO domain became inactive and I tried to activate it again. In RHEV this worked fine, but in oVirt it didn't. Just for your information: both - RHEV and oVirt use "Local on host" as datacenter storage type. I normally use a local NFS server and mount the share locally (dc with storage type NFS) as "Local on host" is making troubles in most of my setups (in both - oVirt and RHEV) and the issues are mainly missing (sometimes lost) volume groups. As my oVirt 3.2 setup is a testing environment and my test vms are still running, I'll keep it in this state for finding a solution for this. As said, have seen issues like this more then one time before, so maybe this is a bug and need some attention (can also open a bug report if needed). vdsm.log is telling me that the storage domain doesn't exist (as complained by vdsm daemon): 2013-05-07 16:44:18,493 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.ActivateStorageDomainVDSCommand] (pool-3-thread-47) [210a0bcb] START, ActivateStorageDomainVDSCommand( storagePoolId = 484e62d7-7a01-4b5e-aec8-59d366100281, ignoreFailoverLimit = false, compatabilityVersion = null, storageDomainId = a4c43175-ce34-49a5-8608-cac573bf7647), log id: 33c54af7 2013-05-07 16:44:20,770 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.BrokerCommandBase] (pool-3-thread-47) [210a0bcb] Failed in ActivateStorageDomainVDS method 2013-05-07 16:44:20,781 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.BrokerCommandBase] (pool-3-thread-47) [210a0bcb] Error code StorageDomainDoesNotExist and error message IRSGenericException: IRSErrorException: Failed to ActivateStorageDomainVDS, error = Storage domain does not exist: ('a4c43175-ce34-49a5-8608-cac573bf7647',) 2013-05-07 16:44:20,791 ERROR [org.ovirt.engine.core.vdsbroker.irsbroker.IrsBrokerCommand] (pool-3-thread-47) [210a0bcb] IrsBroker::Failed::ActivateStorageDomainVDS due to: IRSErrorException: IRSGenericException: IRSErrorException: Failed to ActivateStorageDomainVDS, error = Storage domain does not exist: ('a4c43175-ce34-49a5-8608-cac573bf7647',) More interesting is the behavior of my host (CentOS 6.4) which tries to find a logical volume and is doing some iSCSI-scans: Thread-224450::DEBUG::2013-05-07 16:44:19,333::task::957::TaskManager.Task::(_decref) Task=`ab00697e-32df-43b1-822b-a94bef55909d`::ref 0 aborting False Thread-1129392::DEBUG::2013-05-07 16:44:20,555::misc::84::Storage.Misc.excCmd::(<lambda>) '/usr/bin/sudo -n /sbin/multipath' (cwd None) Thread-1129392::DEBUG::2013-05-07 16:44:20,608::misc::84::Storage.Misc.excCmd::(<lambda>) SUCCESS: <err> = '';

[Users] deploy without engine.conf.defaults?
by lof yer 07 May '13

07 May '13

I compiled the latest source yesterday, but I met a problem in deploying it. I used old env-variable: ENGINE_DEFAULTS=/home/demo/gittest/virtfan-ovirt/backend/manager/conf/engine.conf.defaults and engine.conf.defaults had content like this: ENGINE_USR=/usr/share/ovirt-engine ENGINE_ETC=/etc/ovirt-engine When I ran standalone.sh, it just tell me that I need more variables like ENGINE_PKI_ENGINE_STORE and etc.. What should I add exactly?

[Users] Logical Networks and hosts
by Lee Jones 05 May '13

05 May '13

I have assigned a logical network to a cluster in a data center.I assigned a host host1 to this cluster. I then created a second data center DC2 with cluster DC2. The DC2 cluster has no logical networks assigned to it,but I am still able to assign host1 to this cluster.Is this working as designed? Thanks, Lee

[Users] Fault tolerant storage
by Jakub Bittner 02 May '13

02 May '13

Hi, would it be possible in near future to use for example 2 attached DATA storage (iSCSi, or so) as fault tolerant storage? I mean I have two data storage connected to data center and they include exactly same data and my VMs runs from one and all changes are mirrored to second like RAID 1 and if one storage fails everything switch to second storage without user notice?

[Users] Attach export domain
by Jakub Bittner 02 May '13

02 May '13

Hello, I exported 3 VMs to export domain, than the ovirt engine fails and I installed new version of ovirt engine. If I import export domain with exported VMs I can not attach it to DC, because it says it is used by another DC. Is there a way how to "force" attach that export domain to DC? Thank you, Jakub Bittner
