Could it be some parameter that specifies the limit of VM size? Let me dig around.

But I get an error when choosing the option "Boot from image (creates new volume)" This stats according to "nova hypervisor-stats" show I'm out of free disk space. i.e. the "free_disk_ge" is negative and the number is -864. root@opst-ctrl1-dev:/# nova hypervisor-stats +----------------------+--------+ | Property | Value | +----------------------+--------+ | count | 5 | | current_workload | 4 | | disk_available_least | 236 | | free_disk_gb | -864 | | free_ram_mb | 412826 | | local_gb | 386 | | local_gb_used | 1250 | | memory_mb | 547482 | | memory_mb_used | 134656 | | running_vms | 46 | | vcpus | 144 | | vcpus_used | 72 | The stats in Horizon are coherent with these stats, When I look at the Admin->Hypervisors->Hypervisor Summary I see the same restult Disk Usage Used 1.2TB of 386GB i.e. the result is -814 (negative). But my vg0 volume groups on all computer nodes still have plenty of space left, i.e. some 80+ GB. According to the error, it has to do with the cinder servcie (block device) ; Error: Failed to launch instance "yp-test-33": Please try again later [Error: Build of instance be93dfeb-02eb-4ebb-989d-c033f24b5191 aborted: Failure prepping block device.]. I've created cinder-volumes on all computer nodes, and each cinder volume group has 800 GB disk. Disk Usage Used 1.2TB of 386GB When I look at the "cinder stats" I can not find But for this particular tenant ( which I used when trying to launch the instance) , this is the usage, and there should be enough resources, root@opst-ctrl1-dev:/# cinder quota-usage 7c0b82b2ace9471c92ae87f675e562f6 +-----------+--------+----------+-------+ | Type | In_use | Reserved | Limit | +-----------+--------+----------+-------+ | gigabytes | 711 | 0 | 2000 | | snapshots | 0 | 0 | 30 | | volumes | 15 | 0 | 30 | +-----------+--------+----------+-------+ root@opst-ctrl1-dev:/# cinder quota-show 7c0b82b2ace9471c92ae87f675e562f6 +-----------+-------+ | Property | Value | +-----------+-------+ | gigabytes | 2000 | | snapshots | 30 | | volumes | 30 | +-----------+-------+ Can anyone please help me on this matter? What stats am I missing? Best regards Yngvi
