I suspect storage trouble but cannot pinpoint it. Did someth. change there with the recent async release? The storage domain is NFS3 via a 1G link to a ZFS storage appliance. The export is working quite fast; tested with iozone running for over 24h without problems. It starts with the "Verifying sanlock lockspace initialization" phase; which lasts about 7min (!). In the end it seems sanlock is locking the domain down. I can only get it back by stopping sanlock and vdsm. Attached is the full vdsm lock. Thanks! vdsm: Thread-27::ERROR::2015-05-12 19:17:51,470::domainMonitor::256::Storage.DomainMonitorThread::(_monit orDomain) Error while collecting domain 2f83ea82-e110-465d-a2a6-ac30534a9f6a
