Hello, I have a small export domain while doing a test. So I would like to temporarily lower down warning and critical to the minimum, so that I complete the test and then I re-enable default ones: Initial situation with "engine-config -g" CriticalSpaceActionBlocker: 5 version: general WarningLowSpaceIndicator: 10 version: general This is confirmed by what I see in RACTOREXP export storage domain general pane: Size: 49 GB Available: 38 GB Used: 11 GB Warning Low Space Indicator: 10% (4 GB) Critical Space Action Blocker: 5 GB I set both to 1 [root@ovmgr1 ~]# engine-config -s WarningLowSpaceIndicator=5 [root@ovmgr1 ~]# engine-config -s CriticalSpaceActionBlocker=1 Systemctl restart ovirt-engine [root@ovmgr1 ~]# engine-config -a|grep "Space[A,I]" CriticalSpaceActionBlocker: 1 version: general WarningLowSpaceIndicator: 1 version: general [root@ovmgr1 ~]# But the storage domain still shows the previous values in webadmin gui. I tried also to put in maintenance the storage domain and then activate it again but no change. And if I try to export a VM with 30Gb of disk I get the error and in the engine log 2017-02-12 20:44:44,872+01 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.GetVmsInfoVDSCommand] (default task-1 2) [97705aa9-f082-4e79-9e6b-b5bf0dde3666] START, GetVmsInfoVDSCommand( GetVmsInfoVDSCommandParameters:{runAsync=' true', storagePoolId='588237b8-0031-02f6-035d-000000000136', ignoreFailoverLimit='false', storageDomainId='8846db3f-6e07-4468-bbfc-bf5fbc3f8eef', vmIdList='null'}), log id: 2b56a855 2017-02-12 20:44:45,882+01 INFO [org.ovirt.engine.core.vdsbroker.irsbroker.GetVmsInfoVDSCommand] (default task-1 2) [97705aa9-f082-4e79-9e6b-b5bf0dde3666] FINISH, GetVmsInfoVDSCommand, log id: 2b56a855 2017-02-12 20:44:47,324+01 INFO [org.ovirt.engine.core.bll.exportimport.ExportVmCommand] (default task-14) [dd88227e-7224-4e02-b2b9-11cb3e6d9ce4] Lock Acquired to object 'EngineLock:{exclusiveLocks='[7c9c686f-6cc6-4db7-8bdd-ee11b82a5266=<VM, ACTION_TYPE_FAILED_OBJECT_LOCKED>]', sharedLocks='null'}' 2017-02-12 20:44:47,382+01 WARN [org.ovirt.engine.core.bll.exportimport.ExportVmCommand] (default task-14) [dd88227e-7224-4e02-b2b9-11cb3e6d9ce4] Validation of action 'ExportVm' failed for user admin@internal-authz.
