Adjust clock skew for Ceph Members in a specified Cluster.

In QuantaStor, the "Fix Ceph Cluster Clock Skew" feature is designed to address and resolve clock skew issues within a Ceph cluster.

Clock skew refers to the difference in time between different nodes or components within a distributed system. In a Ceph cluster, accurate and synchronized clocks are crucial for proper operation and coordination of data storage and retrieval.

The purpose of the "Fix Ceph Cluster Clock Skew" function is to identify and rectify any clock skew that may exist among the nodes of the Ceph cluster. By resolving clock skew issues, the feature helps ensure consistent and reliable operation of the cluster and prevents potential data inconsistencies or system disruptions.

The "Fix Ceph Cluster Clock Skew" feature typically performs the following actions:

  • Detection of Clock Skew: It identifies nodes within the Ceph cluster that have significant time differences compared to the reference clock or other cluster nodes.
  • Time Synchronization: The feature initiates the synchronization of clocks across the cluster nodes, ensuring that they are aligned to a common time reference. This synchronization can be achieved using network time protocols (NTP) or other time synchronization mechanisms.
  • Verification and Correction: Once the clocks are synchronized, the feature verifies the consistency of time across the cluster and corrects any remaining clock discrepancies.

By using the "Fix Ceph Cluster Clock Skew" feature, administrators can mitigate clock skew issues that may arise due to varying clock drift rates, network delays, or other factors. This helps maintain the integrity and reliability of data stored in the Ceph cluster.

It's worth noting that clock skew can have a significant impact on the performance and reliability of a distributed storage system like Ceph. Therefore, it's important to monitor and address clock skew issues promptly to avoid potential data corruption or system instability.

As with any cluster management operation, it is advisable to consult the QuantaStor documentation or seek guidance from QuantaStor support resources for specific instructions and best practices related to fixing Ceph cluster clock skew in your QuantaStor environment.
