Dear all, I am running CloudStack version 4.2.0 with KVM hypervisor, Ceph RBD primary storage and NFS secondary storage.
Since yesterday, I am not able to create/register a new template. Normally I would be converting a root-disk volume into a template. In this case, the process of creating the template will take forever and will never complete. On management-server log, there is not much information other than a line stating that the template is being copied: ==== 2013-12-03 17:43:33,340 DEBUG [agent.transport.Request] (Job-Executor-33:job-5446 = [ f6f014b3-7301-4be0-98e9-e6a8caba5e51 ]) Seq 37-2044592856: Sending { Cmd , MgmtId: 161342671900, via: 37, Ver: v1, Flags: 100111, [{"org.apache.cloudstack.storage.command.CopyCommand":{"srcTO":{"org.apache.cloudstack.storage.to.VolumeObjectTO":{"uuid":"10c780a0-d574-4332-bcf4-9988e7ed963d","volumeType":"ROOT","dataStore":{"org.apache.cloudstack.storage.to.PrimaryDataStoreTO":{"uuid":"d433809b-01ea-3947-ba0f-48077244e4d6","id":214,"poolType":"RBD","host":" xxxxxx.xx.com","path":"xxxxxx-xx-01","port":6789}},"name":"ROOT-281","size":10737418240,"path":"d9d5f42f-0c57-4b17-a093-f1172ba24b81","volumeId":306,"vmName":"i-2-281-VM","accountId":2,"format":"RAW","id":306,"hypervisorType":"KVM"}},"destTO":{"org.apache.cloudstack.storage.to.TemplateObjectTO":{"path":"template/tmpl/2/345","uuid":"73732183-69f7-47de-b2e8-556326ca989b","id":345,"format":"RAW","accountId":2,"hvm":true,"displayText":"CentOS 5.10 (64-bit) 20131203a","imageDataStore":{"com.cloud.agent.api.to.NfsTO":{"_url":"nfs://x.x.x.x/mnt/vol1/sec-storage2","_role":"Image"}},"name":"2c8002031-3971-33af-b59f-6f7b52011437","hypervisorType":"KVM"}},"executeInSequence":true,"wait":10800}}] } ==== Logs from SSVM /var/log/cloud/cloud.out: ==== 2013-12-03 11:18:58,137 WARN [storage.template.DownloadManagerImpl] (agentRequest-Handler-3:null) Post download installation was not completed for /mnt/SecStorage/41cab17f-4dbc-37a5-b8d2-cdc153301319/template/tmpl/2/343 2013-12-03 11:18:58,159 WARN [storage.template.DownloadManagerImpl] (agentRequest-Handler-3:null) Post download installation was not completed for /mnt/SecStorage/41cab17f-4dbc-37a5-b8d2-cdc153301319/template/tmpl/2/276 2013-12-03 11:18:58,186 WARN [storage.template.DownloadManagerImpl] (agentRequest-Handler-3:null) Post download installation was not completed for /mnt/SecStorage/41cab17f-4dbc-37a5-b8d2-cdc153301319/template/tmpl/2/275 2013-12-03 11:18:58,220 WARN [storage.template.DownloadManagerImpl] (agentRequest-Handler-3:null) Post download installation was not completed for /mnt/SecStorage/41cab17f-4dbc-37a5-b8d2-cdc153301319/template/tmpl/2/277 2013-12-03 11:18:58,234 WARN [storage.template.DownloadManagerImpl] (agentRequest-Handler-3:null) Post download installation was not completed for /mnt/SecStorage/41cab17f-4dbc-37a5-b8d2-cdc153301319/template/tmpl/2/225 ==== After a while, the process will block other processes, i.e. I will not be able to create a new VM or start/stop any VMs, it seems that it's waiting for the template creation process to complete (which never completes). So I would need to restart the cloudstack-management service on the management server for the day-to-day operation to continue. Status of the created template would be: Ready: No Status: (empty) Size: (empty) I have done all the SSVM health checks as mentioned on this URL: https://cwiki.apache.org/confluence/display/CLOUDSTACK/SSVM,+templates,+Secondary+storage+troubleshooting And I can confirm that the SSVM is running fine, health checks passed. I have tried to restart the SSVM service (service cloud restart) and even stop and start the SSVM but the problem still persists and the templates will never get created. Any advice on how I can further troubleshoot this problem? Looking forward to your reply, thank you. Cheers.
