Hi everybody, we are running an oVirt 4.3.10 production cluster with 9 hosts and 5 datastore domains. Since yesterday we get error messages 26.02.2021 02:00:48 VDSM command SetVolumeDescriptionVDS failed: Could not acquire resource. Probably resource factory threw an exception.: () 26.02.2021 02:00:48 Failed to update OVF disks 5aa438e3-8d22-4b6c-bccf-a843151ca0be, OVF data isn't updated on those OVF stores (Data Center datacenter01, Storage Domain vmstore13). 26.02.2021 02:00:48 Failed to update VMs/Templates OVF data for Storage Domain vmstore13 in Data Center datacenter01. every hour. Only one domain (vmstore13) is affected, this domain is (like 3 others in the cluster) based on glusterfs. Trying to update the OVF's manually from the engine web-gui leads to the same result followed by (a misleading) 26.02.2021 02:00:49 OVF_STORE for domain vmstore13 was updated by admin@internal-authz. The vm's with discs on the affected domain are running fine, snapshots are working. So far I have tried to move the SPM role to another host. This succeeded, but the error messages persist. The vdsm log on the SPM host contains something like 2021-02-26 03:00:57,701+0100 INFO (jsonrpc/2) [vdsm.api] START setVolumeDescription(sdUUID=u'9f731135-f5d9-4609-9e3b-fa9cae75e314', spUUID=u'33e8dc9e-8bc8-11ea-bd76-00163e741033', imgUUID=u'5aa438e3-8d22-4b6c-bccf-a843151ca0be', volUUID=u'0795e58c-4960-413a-a0b4-e8a6d547fda5', description=u'{"Updated":false,"Last Updated":"Wed Feb 24 17:48:17 CET 2021","Storage Domains":[{"uuid":"9f731135-f5d9-4609-9e3b-fa9cae75e314"}],"Disk Description":"OVF_STORE"}', options=None) from=::ffff:10.70.1.1,46968, flow_id=1f314676, task_id=9101db01-b4f0-447e-a5a9-b6af76278d55 (api:48) 2021-02-26 03:00:57,712+0100 ERROR (jsonrpc/2) [storage.VolumeManifest] [Errno 116] Stale file handle (fileVolume:155) for each error, I have attached the relevant part of vdsm.log. Has anyone experienced this behaviour before and can provide help ? -- juergen
