[ovirt-users] Re: alertMessage, [Warning! Low confirmed free space on gluster volume M2Stick1]

Hello, With my first "in Ovirt" made Gluster Storage I am getting some annoying Warnings. On the Hypervisor(s) engine.log : 2019-03-05 13:07:45,281+01 INFO  [org.ovirt.engine.core.vdsbroker.gluster.GetGlusterVolumeAdvancedDetailsVDSCommand] (DefaultQuartzScheduler5) [59957167] START, GetGlusterVolumeAdvancedDetailsVDSCommand(HostName = Hausesel3, GlusterVolumeAdvancedDetailsVDSParameters:{hostId='d7db584e-03e3-4a37-abc7-73012a9f5ba8', volumeName='M2Stick1'}), log id: 74482de6 2019-03-05 13:07:46,814+01 INFO  [org.ovirt.engine.core.bll.lock.InMemoryLockManager] (DefaultQuartzScheduler10) [6d40c5d0] Failed to acquire lock and wait lock 'EngineLock:{exclusiveLocks='[27f8ed93-c857-41ae-af16-e1af9f0b62d4=GLUSTER]', sharedLocks=''}' 2019-03-05 13:07:46,823+01 INFO  [org.ovirt.engine.core.vdsbroker.gluster.GetGlusterVolumeAdvancedDetailsVDSCommand] (DefaultQuartzScheduler5) [59957167] FINISH, GetGlusterVolumeAdvancedDetailsVDSCommand, return: org.ovirt.engine.core.common.businessentities.gluster.GlusterVolumeAdvancedDetails@868edb00, log id: 74482de6 I find no other correlated messages in the Gluster logs.  Where else should I look? It (seems) to work very well. Just these "Warnings" which only worry me due to the "Failed to acquire lock" messages. This is one of 3 Gluster Storage Domains. The other 2 were "Hand made" and exist since Ovirt-3.5 and show no messages. 1x standalone engine 6x Hypervisors  in 2 clusters. One other special condition: I am in the processes of moving my VM's to a second cluster (same Data Center) with a different defined Gluster Network. (New 10Gb cards). All Hypervisors see all Networks. but since there is only one SPM, the SPM is never a "Gluster Peer" of all Domains due to the "only one Gluster Network per Cluster" definition.  Is this the Problem/Situation? There is another "Hand Made" Domain in the new Cluster but it does not have any problems.  The only difference between the two is that the new Domain was created over the Ovirt Web interface. Cheers, Robert O'Kane engine: libgovirt-0.3.4-1.el7.x86_64 libvirt-bash-completion-4.5.0-10.el7_6.4.x86_64 libvirt-client-4.5.0-10.el7_6.4.x86_64 libvirt-daemon-4.5.0-10.el7_6.4.x86_64
