Answer

  • When copying a large number of files (approximately 1 million files, 1.8TB) using CIFS, several potential issues may arise.
  • Here are the common issues and their solutions:
    • Audit Log Growth:
      • Issue: The audit logs on the NAS may grow significantly, potentially impacting service availability.
      • Solution: Temporarily disable audit logging during the file migration process to prevent log growth from affecting the system.
    • Inode Depletion:
      • Issue: The volume may run out of inodes, preventing further file operations.
      • Solution: Increase the inode limit on the volume to accommodate the large number of files.
    • Performance Impact:
      • Issue: It is difficult to predict the exact performance impact without running the copy process in the actual environment
      • Solution: Monitor the performance during the copy process.adjust QoS settings if necessary.
