openstack渣渣VolumeSizeExceedsAvailableQuota tips错配体积类型

Question

创建卷将显示相同的错误提示，无论使用什么--type选项。

# openstack volume create --size 500 test_vol
VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed gigabytes quota.
 Requested 500G, quota is 965362G and 965362G has been consumed.

# openstack volume create --size 500 --type ceph_ssd test_vol_ssd
VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed gigabytes quota.
 Requested 500G, quota is 965362G and 965362G has been consumed.

# openstack quota show
| Field                 | Value   |
| gigabytes             | 965362  |
| gigabytes___DEFAULT__ | -1      |
| gigabytes_ceph_ssd    | 9965362 |

有时，当创建一个gigabytes_ceph_ssd卷类型时，它会提示ceph_ssd配额超过了。如下所示：

# openstack volume create --size 500 --type ceph_ssd test_vol_ssd
VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed gigabytes_ceph_ssd quota.

这有什么问题吗？我怎样才能解决这个问题？有什么是我误解的吗？

为我的无知感到羞耻。

千兆字节的意思是Volume gigabytes allowed for each project。

它将检查exception.OverQuota以前是否用于创建新卷。首先将检查所有卷容量的gigabytes_specify_volume_type G字节，然后检查 with create with --type选项。

在开发环境中验证：

$ openstack volume create --size 10 --type ceph_ssd test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes_ceph_ssd quota. Requested 10G, quota is 16753G and 16745G has been consumed.

$ openstack volume create --size 100 test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes quota. Requested 100G, quota is 1280970G and 1280951G has been consumed.

### created success, consumed will add +8G in gigabytes
$ openstack volume create --size 8 --type ceph_ssd test_vol4
$ openstack volume create --size 100 test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes quota. Requested 100G, quota is 1280970G and 1280959G has been consumed.

### check quota pass by gigabytes default by not gigabytes_ceph_ssd
$ openstack volume create --size 11 --type ceph_ssd test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes_ceph_ssd quota. Requested 11G, quota is 16753G and 16753G has been consumed.

### check quota not pass by gigabytes default
$ openstack volume create --size 12 --type ceph_ssd test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes quota. Requested 12G, quota is 1280970G and 1280959G has been consumed.

### without limit by gigabytes default quota
$ openstack quota set --gigabytes -1 proj_name
$ openstack volume create --size 12 --type ceph_ssd test_vol4
VolumeSizeExceedsAvailableQuota: ... gigabytes_ceph_ssd quota. Requested 12G, quota is 16753G and 16753G has been consumed.

### according to the CapacityWeigher, it will distribute the volume to ceph_ssd backend without specify volume type
### we have two backend ceph pool: ceph_hdd(capacity smaller than the other), ceph_ssd
### it will no check the quota of gigabytes_ceph_ssd, bcz create without --type option
$ openstack volume create --size 100 test_vol5
$ openstack volume show test_vol5
