7.11. 操作失败的故障排除
如果共享文件系统服务(manila)操作（如创建共享或创建共享组）异步失败，您可以作为最终用户从命令行运行查询，以了解更多有关错误的信息。
7.11.1. 修复创建共享或创建共享组失败
在本例中，最终用户的目标是在多个虚拟机上创建一个共享来托管软件库。示例错误地引入了两个共享创建失败，以说明如何使用命令行来检索用户支持消息。
流程
要创建共享，您可以使用共享类型指定您希望共享具有的一些功能。云管理员可以创建共享类型。查看可用的共享类型：
clouduser1@client:~$ manila type-list +--------------------------------------+-------------+------------+------------+--------------------------------------+--------------------------------------------+-------------+ | ID | Name | visibility | is_default | required_extra_specs | optional_extra_specs | Description | +--------------------------------------+-------------+------------+------------+--------------------------------------+--------------------------------------------+-------------+ | 1cf5d45a-61b3-44d1-8ec7-89a21f51a4d4 | dhss_false | public | YES | driver_handles_share_servers : False | create_share_from_snapshot_support : True | None | | | | | | | mount_snapshot_support : False | | | | | | | | revert_to_snapshot_support : False | | | | | | | | snapshot_support : True | | | 277c1089-127f-426e-9b12-711845991ea1 | dhss_true | public | - | driver_handles_share_servers : True | create_share_from_snapshot_support : True | None | | | | | | | mount_snapshot_support : False | | | | | | | | revert_to_snapshot_support : False | | | | | | | | snapshot_support : True | | +--------------------------------------+-------------+------------+------------+--------------------------------------+--------------------------------------------+-------------+
在本例中，有两个共享类型可用。
要使用指定
driver_handles_share_servers=true功能的共享类型，您必须创建一个共享网络来导出共享。从专用项目网络创建共享网络。clouduser1@client:~$ openstack subnet list +--------------------------------------+---------------------+--------------------------------------+---------------------+ | ID | Name | Network | Subnet | +--------------------------------------+---------------------+--------------------------------------+---------------------+ | 78c6ac57-bba7-4922-ab81-16cde31c2d06 | private-subnet | 74d5cfb3-5dd0-43f7-b1b2-5b544cb16212 | 10.0.0.0/26 | | a344682c-718d-4825-a87a-3622b4d3a771 | ipv6-private-subnet | 74d5cfb3-5dd0-43f7-b1b2-5b544cb16212 | fd36:18fc:a8e9::/64 | +--------------------------------------+---------------------+--------------------------------------+---------------------+ clouduser1@client:~$ manila share-network-create \ --name mynet \ --neutron-net-id 74d5cfb3-5dd0-43f7-b1b2-5b544cb16212 \ --neutron-subnet-id 78c6ac57-bba7-4922-ab81-16cde31c2d06 +-------------------+--------------------------------------+ | Property | Value | +-------------------+--------------------------------------+ | network_type | None | | name | mynet | | segmentation_id | None | | created_at | 2018-10-09T21:32:22.485399 | | neutron_subnet_id | 78c6ac57-bba7-4922-ab81-16cde31c2d06 | | updated_at | None | | mtu | None | | gateway | None | | neutron_net_id | 74d5cfb3-5dd0-43f7-b1b2-5b544cb16212 | | ip_version | None | | cidr | None | | project_id | cadd7139bc3148b8973df097c0911016 | | id | 0b0fc320-d4b5-44a1-a1ae-800c56de550c | | description | None | +-------------------+--------------------------------------+ clouduser1@client:~$ manila share-network-list +--------------------------------------+-------+ | id | name | +--------------------------------------+-------+ | 6c7ef9ef-3591-48b6-b18a-71a03059edd5 | mynet | +--------------------------------------+-------+

在本例中，共享创建过程中出现错误。
要查看用户支持消息，请运行
message-list命令。使用--resource-id过滤到您要查找的特定共享。clouduser1@client:~$ manila message-list +--------------------------------------+---------------+--------------------------------------+-----------+----------------------------------------------------------------------------------------------------------+-----------+----------------------------+ | ID | Resource Type | Resource ID | Action ID | User Message | Detail ID | Created At | +--------------------------------------+---------------+--------------------------------------+-----------+----------------------------------------------------------------------------------------------------------+-----------+----------------------------+ | 7d411c3c-46d9-433f-9e21-c04ca30b209c | SHARE | 243f3a51-0624-4bdd-950e-7ed190b53b67 | 001 | allocate host: No storage could be allocated for this share request, Capabilities filter didn't succeed. | 008 | 2018-10-09T21:12:21.000000 | +--------------------------------------+---------------+--------------------------------------+-----------+----------------------------------------------------------------------------------------------------------+-----------+----------------------------+

作为云用户，您可以通过共享类型检查功能，以便您可以查看可用的共享类型。两种共享类型之间的区别是

7.11.2. 调试共享挂载失败
如果您在挂载共享时遇到问题，请使用这些验证步骤来识别根本原因。
流程
验证共享的访问控制列表，以确保与您的客户端对应的规则正确且已成功应用。
$ manila access-list share-01
在成功规则中，
state属性等于active。如果 share type 参数被配置为
driver_handles_share_servers=false，请从导出位置复制主机名或 IP 地址，并 ping 以确认与 NAS 服务器的连接：$ ping -c 1 198.51.100.13 PING 198.51.100.13 (198.51.100.13) 56(84) bytes of data. 64 bytes from 198.51.100.13: icmp_seq=1 ttl=64 time=0.048 ms--- 198.51.100.13 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 7.851/7.851/7.851/0.000 ms If using the NFS protocol, you may verify that the NFS server is ready to respond to NFS rpcs on the proper port: $ rpcinfo -T tcp -a 198.51.100.13.8.1 100003 4 program 100003 version 4 ready and waiting
注意IP 地址以通用地址格式(uaddr)编写，它添加了两个额外的 octets (8.1)来代表 NFS 服务端口 2049。
如果这些验证步骤失败，则可能存在网络连接问题，或者您的共享文件系统后端存储失败。收集日志文件并联系红帽支持。
