Troubleshoot Shared File Systems service

Failures in Share File Systems service during a share creation

If new shares go into error state during creation, follow next steps:

1. Make sure, that share services are running in debug mode. If the debug mode is not set, you will not get any tips from logs how to fix your issue.
2. Find what share service holds a specified share. To do that, run command manila show <share_id_or_name> and find a share host in the output. Host uniquely identifies what share service holds the broken share.
3. Look thought logs of this share service. Usually, it can be found at /etc/var/log/manila-share.log. This log should contain kind of traceback with extra information to help you to find the origin of issues.

No valid host was found

You should manage share types very carefully. If share type contains invalid extra spec scheduler will never find a valid host for shares of this type. To diagnose this issue, make sure that scheduler service is running in debug mode, try to create a new share and look for message Failed to schedule create_share: No valid host was found. in /etc/var/log/manila-scheduler.log.

To solve this issue look carefully through the list of extra specs in the share type and list of share services reported capabilities. Make sure that extra specs are pointed in the right way.

Created share is unreachable

By default, a new share does not have any active access rules. To provide access to new created share, you need to create appropriate access rule with right value that defines access.

Service becomes unavailable after upgrade

After upgrading the Shared File Systems service from version v1 to version v2.x, please be attentive to update the service endpoint in the OpenStack Identity service. Use keystone service-list to get service type related to Shared File Systems service and then keystone service-list --service <share-service-type> command. You will get the endpoints expected from running the Shared File Systems service. Make sure that these endpoints are updated. If it is not true, you need to delete the outdated endpoints and create new ones.

Failures during management of internal resources

Some drivers in the Shared File Systems service can create service entities, like servers and networks. If it is necessary to reach it you can log in to tenant service and get manual control over it.
