Answer

  • The default disk block size for WAFL is 4k, which is equal to LUN's physical block size.
  • Verify the block size using the nodeshell "vol status -b" command.
::*> node run -node node01 -command vol status -b
Volume              Block Size (bytes)  Vol Size (blocks)   FS Size (blocks)
------              ------------------  ------------------  ----------------
vol1                4096                131072000           131072000
