Event Summary

This message occurs when a directory surpasses 90% of its current maximum directory size or when a directory has reached its maximum directory size (maxdirsize) limit.

  • When a directory hits the maximum default or configured value of maxdirsize, any new file creates will likely fail. 
  • The directory may begin to allow saving new writes if there is a background cleanup operation running (i.e. a snap delete following file deletion)

 

wafl.dir.size.max.warning
