PowerStore Alerts: File System is Not in Production Mode

Summary: In PowerStore Metro Sync replication, if a file system (FS) is not synchronized, a disaster recovery (DR) failover fails, resulting in the file system being unreachable.

Symptoms

  • Some or all File Systems did not failover to DR
  • File systems that are out of sync - These do not fail over during a disaster recovery (DR) event and become unreachable, making their data unavailable
  • File systems that are synchronized - These successfully fail over to the destination system, ensuring continued access
  • The Alert ID and Error code detailing the associated File System and NAS Server affected is presented
Alert ID SDNAS_CP_FILE_SYSTEM_MODE_NOT_IN_PRODUCTION
Alert Text File system %(fs_name) is not reachable after DR failover failed on replication session associated with NAS Server %(nas_server_name).
Error Code 0x01C01E01

Cause

The DR failover fails because PowerStore Metro Sync requires all file systems to be fully synchronized before initiating the failover. This applies to both Planned and Unplanned Failover events.

If any file system is out of sync, the failover process cannot complete for those file systems, resulting in unreachable data. This behavior is intentional to prevent an unsynchronized file system from entering production mode at the DR site, thereby safeguarding data integrity at the source site.

Resolution

To resolve the issue, choose one of the following options:

  • Option 1: Restore and Resynchronize

    • Bring the source system online.
    • Wait for data synchronization to complete with the destination site.
    • Verify the sync status of file system sessions (previously out of sync) using PowerStore Manager.
    • If required, retry the failover once synchronization is confirmed.

  • Option 2: Forced Failover (Data Loss Risk!)

    • Perform a forced failover, accepting the risk of data loss, to bring the file system into production mode at the destination site.
