Chapter 2: SHA Troubleshooting 2.2.33 Warning: Errors detected in certain services Warning Errors detected in certain services. Details: The system detected some errors in the following services on passive server My_ Passive_Hostname: Service A. Suggestion: Restart passive server My_Passive_Hostname. If the problem persists, please contact Synology Technical Support for further assistance. Description • The system detected an error on one of the monitored services. • The active server will perform auto-failover whenever it detects an error in the monitored service (as long as the passive server is functioning normally). Once the failover is completed, the cluster will enter this state. • The system will continue to provide services normally. However, since there are still errors on the new passive server, failover and switchover functions will be unavailable. Cause • The monitored service was abnormal on the original active server, so the system failed over to the passive server. • After auto-failover, the active server where the problem occurred will become the passive server and this warning will occur. Resolution 1. Restart the passive server where the problem occurred. 2. If the issue persists, refer to Chapter 3: Contact Customer Service to contact Synology Technical Support for further assistance. Related Notifications • Status of high-availability cluster My_SHA_Hostname is abnormal [Details: Service failure detected on My_Passive_Hostname (passive server)] Possible Logs • [warning] Auto failover is temporarily unavailable: Service failure detected on My_Passive_Hostname (passive server). 2.2.34 Warning: Failed to sync data from the active server to the passive server [Suggestion: Click Recovery to recover My_Passive_Hostname.] Warning Failed to sync data from active server My_Active_Hostname to passive server My_Passive_ Hostname. Suggestion: Click Recovery to recover My_Passive_Hostname. Description The active server cannot be synced to the passive server. The data on the active server can be accessed normally, but the data on the passive server may be inconsistent. Cause The data cannot be properly synchronized because either the network connection or the passive server's storage space are abnormal. 34
