Will Wafliron impact system performance

Last Updated:

Applies to

  • ONTAP 9


Once Phase 1 of Wafliron completes, data will be served while Wafliron is running on the remaining data. There may be a performance penalty depending on several factors.  For example:

  • The file system structure
  • Client access patterns
  • Storage system load
  • Storage system platform
  • Available memory
  • The extent of inconsistencies in the file system

When clients attempt to access data, Wafliron must first check the data before fulfilling clients' requests. This behavior ensures the clients receive consistent data and prevents the storage system from panicking should clients touch inconsistent data.  While Wafliron is scanning, there may be a performance impact for client access.
